2018-05-30Fix missing Cycles 3D viewport updates when editing materials, lamps.Brecht Van Lommel
This introduces a new depsgraph API for getting updated datablocks, rather than getting it from bpy.data. * depsgraph.ids_updated gives a list of all datablocks in the depsgraph which have been updated. * depsgraph.id_type_updated('TYPE') is true if any datablock of the given type has been added, removed or modified. More API updates are coming to properly handle multiple depsgraphs and finer update granularity, but this should make Cycles work again.

2018-05-27Cycles: Add Support for IES files as textures for light strengthLukas Stockner
This patch adds support for IES files, a file format that is commonly used to store the directional intensity distribution of light sources. The new IES node is supposed to be plugged into the Strength input of the Emission node of the lamp. Since people generating IES files do not really seem to care about the standard, the parser is flexible enough to accept all test files I have tried. Some common weirdnesses are distributing values over multiple lines that should go into one line, using commas instead of spaces as delimiters and adding various useless stuff at the end of the file. The user interface of the node is similar to the script node, the user can either select an internal Text or load a file. Internally, IES files are handled similar to Image textures: They are stored in slots by the LightManager and each unique IES is assigned to one slot. The local coordinate system of the lamp is used, so that the direction of the light can be changed. For UI reasons, it's usually best to add an area light, rotate it and then change its type, since especially the point light does not immediately show its local coordinate system in the viewport.

2018-05-16Shader Node Editor: Add Closure to RGB convertion node.Clément Foucault
Patch D3205 by Kanzaki Wataru Only implemented in Eevee for now. Collapse a closure to RGBA so we can do NPR stuff on the resulting color. Use an emission shader to convert the color back to a closure. Doing this will break PBR and will kill any SSR and SSS effects the shader the shader rely on. That said screen space refraction and ambient occlusion are supported due to the way they are implemented.
2018-04-19Remove Blender Internal and legacy viewport from Blender 2.8.Ton Roosendaal
Brecht authored this commit, but he gave me the honours to actually do it. Here it goes; Blender Internal. Bye bye, you did great! * Point density, voxel data, ocean, environment map textures were removed, as these only worked within BI rendering. Note that the ocean modifier and the Cycles point density shader node continue to work. * Dynamic paint using material shading was removed, as this only worked with BI. If we ever wanted to support this again probably it should go through the baking API. * GPU shader export through the Python API was removed. This only worked for the old BI GLSL shaders, which no longer exists. Doing something similar for Eevee would be significantly more complicated because it uses a lot of multiplass rendering and logic outside the shader, it's probably impractical. * Collada material import / export code is mostly gone, as it only worked for BI materials. We need to add Cycles / Eevee material support at some point. * The mesh noise operator was removed since it only worked with BI material texture slots. A displacement modifier can be used instead. * The delete texture paint slot operator was removed since it only worked for BI material texture slots. Could be added back with node support. * Not all legacy viewport features are supported in the new viewport, but their code was removed. If we need to bring anything back we can look at older git revisions. * There is some legacy viewport code that I could not remove yet, and some that I probably missed. * Shader node execution code was left mostly intact, even though it is not used anywhere now. We may eventually use this to replace the texture nodes with Cycles / Eevee shader nodes. * The Cycles Bake panel now includes settings for baking multires normal and displacement maps. The underlying code needs to be merged properly, and we plan to add back support for multires AO baking and add support to Cycles baking for features like vertex color, displacement, and other missing baking features. * This commit removes DNA and the Python API for BI material, lamp, world and scene settings. This breaks a lot of addons. * There is more DNA that can be removed or renamed, where Cycles or Eevee are reusing some old BI properties but the names are not really correct anymore. * Texture slots for materials, lamps and world were removed. They remain for brushes, particles and freestyle linestyles. * 'BLENDER_RENDER' remains in the COMPAT_ENGINES of UI panels. Cycles and other renderers use this to find all panels to show, minus a few panels that they have their own replacement for.
2018-04-18Workspaces: remove workspace engine, use 3D viewport draw mode instead.Brecht Van Lommel
ViewRender was removed, which means we can't get the render engine for files saved in 2.8. We assume that any files saved in 2.8 were intended to use Eevee and set the engine to that. A fix included with this is that .blend thumbails now draw with Clay mode, and never Eevee or Cycles. These were drawn with solid mode in 2.7, and should be very fast and not e.g. load heavy image textures. Differential Revision: https://developer.blender.org/D3156
2018-04-16Depsgraph: remove EvaluationContext, pass Depsgraph instead.Brecht Van Lommel
The depsgraph was always created within a fixed evaluation context. Passing both risks the depsgraph and evaluation context not matching, and it complicates the Python API where we'd have to expose both which is not so easy to understand. This also removes the global evaluation context in main, which assumed there to be a single active scene and view layer. Differential Revision: https://developer.blender.org/D3152

2018-01-21Fix old files with changed node socket type not loading correctly.Brecht Van Lommel
This would lead to sock.default_value pointing to the wrong data type, possibly causing crashes. Unfortunately, this bug will still exist for older Blender versions that try to load newer files, which makes changing the type of a node socket problematic.

2017-11-23Rename any instance of scene layer or render layer in code with view layerDalai Felinto
The RenderResult struct still has a listbase of RenderLayer, but that's ok since this is strictly for rendering. * Subversion bump (to 2.80.2) * DNA low level doversion (renames) - only for .blend created since 2.80 started Note: We can't use DNA_struct_elem_find or get file version in init_structDNA, so we are manually iterating over the array of the SDNA elements instead. Note 2: This doversion change with renames can be reverted in a few months. But so far it's required for 2.8 files created between October 2016 and now.

2017-11-22SceneRenderLayer Removal/RefactorDalai Felinto
This patch moves all the functionality previously in SceneRenderLayer to SceneLayer. If we want to rename some of these structs now would be a good time to do it, before they are in SceneLayer. Everything should be working, though I will test things further tomorrow. Once this is committed depsgraph can get rid of the workaround added in rna_Main_meshes_new_from_object and finish whatever this patch was preventing from being finished. This patch also adds a few placeholders for the overrides (samples, ...). These are obviously not working, so some unittests that rely on 'lay', and 'zmask' will fail. This patch does not addressed the change of moving samples to ViewRender (I have this as a separate patch and needs some separate discussion). Following next is the individual note of the individual parts that were committed. Note 1: It is up to Cycles to still get rid of exclude_layer internally. Note 2: Cycles still need to handle its own doversion for the use_layer_samples cases and (1) Remove the override as it is (2) Add a new override (scene.cycles.samples) if scene.cycles.use_layer_samples != IGNORE Respecting the expected behaviour when scene.cycles.use_layer_samples == BOUNDED. Note 3: Cycles still need to implement the per-object holdout (similar to how we do shadow catcher). Note 4: There are parts of the old (Blender Internal) rendering pipeline that is still using lay, e.g., in shi->lay. Honestly it will be easier to purge the entire Blender Internal code away instead of taking things from it bit by bit.

2017-11-08Cycles: add bevel shader, for raytrace based rounded edges.Brecht Van Lommel
The algorithm averages normals from nearby surfaces. It uses the same sampling strategy as BSSRDFs, casting rays along the normal and two orthogonal axes, and combining the samples with MIS. The main concern here is that we are introducing raytracing inside shader evaluation, which could be quite bad for GPU performance and stack memory usage. In practice it doesn't seem so bad though. Note that using this feature can easily slow down renders 20%, and that if you care about performance then it's better to use a bevel modifier. Mainly this is useful for baking, and for cases where the mesh topology makes it difficult for the bevel modifier to work well. Differential Revision: https://developer.blender.org/D2803

2017-10-16Workspace: Move engines to workspace and Properties Editor cleanupDalai Felinto
Engine is not stored in WorkSpaces. That defines the "context" engine, which is used for the entire UI. The engine used for the poll of nodes (add node menu, new nodes when "Use Nodes") is obtained from context. Introduce a ViewRender struct for viewport settings that are defined for workspaces and scene. This struct will be populated with the hand-picked settings that can be defined per workspace as per the 2.8 design. * use_scene_settings * properties editor: workshop + organize context path Use Scene Settings ================== For viewport drawing, Workspaces have an option to use the Scene render settings (F12) instead of the viewport settings. This way users can quickly preview the final render settings, engine and View Layer. This will affect all the editors in that workspace, and it will be clearly indicated in the top-bar. Properties Editor: Add Workspace and organize context path ========================================================== We now have the properties of: Scene, Scene > Layer, Scene > World, Workspace [Scene | Workspace] > Render Layer > Object [Scene | Workspace] > Render Layer > Object > Data (...)

2017-10-16Fix compatibility flag for nodetreeDalai Felinto
NODE_NEWER_SHADING was introduced in e868b459bb8e however it should have been added as a bitflag. BKE_scene_uses_blender_eevee() was used in gpu_shader_output() as a workaround for compatibility being poorly used. Anyways this fixes this situation. This is necessary for an upcoming patch, even though this is considered temporary - since the other NODE_*_SHADING values are legacy from Blender Internal drawing.
2017-08-29Depsgraph: Fix missing updates when tweaking node tree parametersSergey Sharybin
The is following: split copy on write update for node trees, and if we are only tagging for uniform buffer update we skip whole datablock copy and only invoke copy default_values form original nodetree to a copied one. Thing which i'm not sure is: whether we need to use different branches in graph itself to control such a conditional behavior, or whether we need to store tag somewhere in the dependency graph. There are obviously cons and pros in both approaches, and need to think about this. Maybe with more examples it becomes more obvious which way is better. This only fixes manual tweaks for now, animation support is coming.

2017-08-07Refactor ID copying (and to some extent, ID freeing).Bastien Montagne
This will allow much finer controll over how we copy data-blocks, from full copy in Main database, to "lighter" ones (out of Main, inside an already allocated datablock, etc.). This commit also transfers a llot of what was previously handled by per-ID-type custom code to generic ID handling code in BKE_library. Hopefully will avoid in future inconsistencies and missing bits we had all over the codebase in the past. It also adds missing copying handling for a few types, most notably Scene (which where using a fully customized handling previously). Note that the type of allocation used during copying (regular in Main, allocated but outside of Main, or not allocated by ID handling code at all) is stored in ID's, which allows to handle them correctly when freeing. This needs to be taken care of with caution when doing 'weird' unusual things with ID copying and/or allocation! As a final note, while rather noisy, this commit will hopefully not break too much existing branches, old 'API' has been kept for the main part, as a wrapper around new code. Cleaning it up will happen later. Design task : T51804 Phab Diff: D2714

2017-06-20Clean node names and organize menus for eeveeLuca Rood
This makes the node menus aware of the Cycles/Eevee distinction, and only show the relevant nodes for the current engine. Names have also been changed to accomodate for the new output node system.
2017-06-20Implement Eevee output node systemLuca Rood
This makes Eevee consistent with Cycles, by having a single output node, and multiple shader nodes that connect to it. Note that node systems for Eevee saved before this will be missing the output node, and thus will show an invalid material. This is easily resolved by connecting the shader output to a new output node.

2017-05-03Render API/Cycles: Identify Render Passes by their name instead of a type flagLukas Stockner
Previously, every RenderPass would have a bitfield that specified its type. That limits the number of passes to 32, which was reached a while ago. However, most of the code already supported arbitrary RenderPasses since they were also used to store Multilayer EXR images. Therefore, this commit completely removes the passflag from RenderPass and changes all code to use the unique pass name for identification. Since Blender Internal relies on hardcoded passes and to preserve compatibility, 32 pass names are reserved for the old hardcoded passes. To support these arbitrary passes, the Render Result compositor node now adds dynamic sockets. For compatibility, the old hardcoded sockets are always stored and just hidden when the corresponding pass isn't available. To use these changes, the Render Engine API now includes a function that allows render engines to add arbitrary passes to the render result. To be able to add options for these passes, addons can now add their own properties to SceneRenderLayers. To keep the compositor input node updated, render engine plugins have to implement a callback that registers all the passes that will be generated. From a user perspective, nothing should change with this commit. Differential Revision: https://developer.blender.org/D2443 Differential Revision: https://developer.blender.org/D2444

The final refraction roughness has to be calculated using the surface roughness and the refraction roughness because those two are correlated for refractions. If a ray hits a rough surface of a translucent material, it is scattered while entering the surface. Then it is scattered further within the object.

64 outputs Ideally we need to find a way to remove such a static limit here, but it's not so trivial to implement for texture nodes. Requires some bigger system redesign there. Just raising limit for now, which is fine for modern systems.
2017-02-07Render Layers and Collections (merge from render-layers)Dalai Felinto
Design Documents ---------------- * https://wiki.blender.org/index.php/Dev:2.8/Source/Layers * https://wiki.blender.org/index.php/Dev:2.8/Source/DataDesignRevised User Commit Log --------------- * New Layer and Collection system to replace render layers and viewport layers. * A layer is a set of collections of objects (and their drawing options) required for specific tasks. * A collection is a set of objects, equivalent of the old layers in Blender. A collection can be shared across multiple layers. * All Scenes have a master collection that all other collections are children of. * New collection "context" tab (in Properties Editor) * New temporary viewport "collections" panel to control per-collection visibility Missing User Features --------------------- * Collection "Filter" Option to add objects based on their names * Collection Manager operators The existing buttons are placeholders * Collection Manager drawing The editor main region is empty * Collection Override * Per-Collection engine settings This will come as a separate commit, as part of the clay-engine branch Dev Commit Log -------------- * New DNA file (DNA_layer_types.h) with the new structs We are replacing Base by a new extended Base while keeping it backward compatible with some legacy settings (i.e., lay, flag_legacy). Renamed all Base to BaseLegacy to make it clear the areas of code that still need to be converted Note: manual changes were required on - deg_builder_nodes.h, rna_object.c, KX_Light.cpp * Unittesting for main syncronization requirements - read, write, add/copy/remove objects, copy scene, collection link/unlinking, context) * New Editor: Collection Manager Based on patch by Julian Eisel This is extracted from the layer-manager branch. With the following changes: - Renamed references of layer manager to collections manager - I doesn't include the editors/space_collections/ draw and util files - The drawing code itself will be implemented separately by Julian * Base / Object: A little note about them. Original Blender code would try to keep them in sync through the code, juggling flags back and forth. This will now be handled by Depsgraph, keeping Object and Bases more separated throughout the non-rendering code. Scene.base is being cleared in doversion, and the old viewport drawing code was poorly converted to use the new bases while the new viewport code doesn't get merged and replace the old one. Python API Changes ------------------ ``` - scene.layers + # no longer exists - scene.objects + scene.scene_layers.active.objects - scene.objects.active + scene.render_layers.active.objects.active - bpy.context.scene.objects.link() + bpy.context.scene_collection.objects.link() - bpy_extras.object_utils.object_data_add(context, obdata, operator=None, use_active_layer=True, name=None) + bpy_extras.object_utils.object_data_add(context, obdata, operator=None, name=None) - bpy.context.object.select + bpy.context.object.select = True + bpy.context.object.select = False + bpy.context.object.select_get() + bpy.context.object.select_set(action='SELECT') + bpy.context.object.select_set(action='DESELECT') -AddObjectHelper.layers + # no longer exists ```
2016-12-12Cleanup: Get rid of ntreeSwitchID(_ex) functions, use generic ↵Bastien Montagne
BKE_libblock_relink_ex instead.
2016-07-21Refactor/deduplicate even more make_local code (and fix part of T48907).Bastien Montagne
Turns out most BKE_foo_make_local datablock-specific functions are actually doing exactly the same thing, only two currently need special additional operations (object and brush ones). So added a BKE_id_make_local_generic instead of copying same code over and over. Also, changed a bit how make_local works in case we are localizing a whole library. We need to do the 'remap' step (from old linked ID to new local one) in the second loop, otherwise we miss some dependencies. This fixes main part of T48907.
2016-07-14Add option to id_make_local to force localization of datablock, even if not ↵Bastien Montagne
used locally. Will be used by link/append code.
2016-07-10Refactor/enhance ntreeMakeLocal().Bastien Montagne
Now using modern features from libquery/libremap areas. Provides same kind of fixes/improvements as for BKE_object_make_local() (see rBd1a4ae3f395a6).
