2020-11-18Geometry Nodes: initial Random Attribute nodeJacques Lucke
This adds some ui boilerplate code for the Random Attribute node and provides an initial implementation. Note, while the implementation can already randomize attributes, it might not behave as expected under all circumstances yet. It's still work in progress.
2020-11-18Geometry Nodes: Unify icons -> use ICON_NODETREE for everythingDalai Felinto
Until there is a icon made specially for this, the nodetree icon is up for grabs. Using it in the nodegroup + modifier + editor helps the users to make a connection on where to edit those modifiers.

2020-11-03Materials: add custom object properties as uniform attributes.Alexander Gavrilov
This patch allows the user to type a property name into the Attribute node, which will then output the value of the property for each individual object, allowing to e.g. customize shaders by object without duplicating the shader. In order to make supporting this easier for Eevee, it is necessary to explicitly choose whether the attribute is varying or uniform via a dropdown option of the Attribute node. The dropdown also allows choosing whether instancing should be taken into account. The Cycles design treats all attributes as one common namespace, so the Blender interface converts the enum to a name prefix that can't be entered using keyboard. In Eevee, the attributes are provided to the shader via a UBO indexed with resource_id, similar to the existing Object Info data. Unlike it, however, it is necessary to maintain a separate buffer for every requested combination of attributes. This is done using a hash table with the attribute set as the key, as it is expected that technically different but similar materials may use the same set of attributes. In addition, in order to minimize wasted memory, a sparse UBO pool is implemented, so that chunks that don't contain any data don't have to be allocated. The back-end Cycles code is already refactored and committed by Brecht. Differential Revision: https://developer.blender.org/D2057
2020-10-31Geometry Nodes: new Subdivision Surface nodeLéo Depoix
This node is similar to the subdivision surface modifier. It subdivides the mesh component of a geometry. The options have the same meaning as in the modifier. Differential Revision: https://developer.blender.org/D9364

2020-10-26Geometry Nodes: Initial mesh boolean nodeHans Goudey
This uses the code from the rewritten boolean modifier from 2.91 as a node. The implementation is about as minimal as it can get, since for now the use case of this node is mostly to test multiple geometry outputs and inputs. The boolean code requires a BMesh, so the node converts the input meshes to BMesh, so the bmesh is added as a dependency to the nodes module.

We still have to pick a color for this socket. Ref T81848.
2020-10-20Simulation: remove particle nodes with outdated designJacques Lucke
The design for how we approach the "Everything Nodes" project has changed. We will focus on a different part of the project initially. While future me will likely refer back to some of the code I remove here, there is no point in keeping this code around in master currently. It would just confuse other developers working on the project. This does not remove the simulation modifier and data block. Those are just cleaned up, so that the boilerplate code can be reused in the future.

2020-08-04Node Groups: expose the SOCK_HIDE_VALUE flag for node group inputs.Alexander Gavrilov
This flag specifies that even when the socket is not connected, the node should not display the input field for the constant input value. This is useful for inputs like Normal, which have special handling for the missing input case and don't use a constant value. Currently there is no way to change this flag from Python, and through UI it can only be done by re-creating the socket. This patch exposes the flag through RNA and UI, makes sure it is properly updated when changed, and adds special handling to ensure that it is correctly set when creating a node group from a node set that includes reroute nodes.

2020-06-25Cycles: add support for rendering sculpt vertex colorsBrecht Van Lommel
Ref T78041
2020-06-23Sculpt Vertex Colors: Initial implementationPablo Dobarro
Sculpt Vertex Colors is a painting system that runs inside sculpt mode, reusing all its tools and optimizations. This provides much better performance, easier to maintain code and more advanced features (new brush engine, filters, symmetry options, masks and face sets compatibility...). This is also the initial step for future features like vertex painting in Multires and brushes that can sculpt and paint at the same time. This commit includes: - SCULPT_UNDO_COLOR for undo support in sculpt mode - SCULPT_UPDATE_COLOR and PBVH flags and rendering - Sculpt Color API functions - Sculpt capability for sculpt tools (only enabled in the Paint Brush for now) - Rendering support in workbench (default to Sculpt Vertex Colors except in Vertex Paint) - Conversion operator between MPropCol (Sculpt Vertex Colors) and MLoopCol (Vertex Paint) - Remesher reprojection in the Voxel Remehser - Paint Brush and Smear Brush with color smoothing in alt-smooth mode - Parameters for the new brush engine (density, opacity, flow, wet paint mixing, tip scale) implemented in Sculpt Vertex Colors - Color Filter - Color picker (uses S shortcut, replaces smooth) - Color selector in the top bar Reviewed By: brecht Maniphest Tasks: T72866 Differential Revision: https://developer.blender.org/D5975
2020-06-17Cycles: Add new Sky Texture method including direct sunlightLukas Stockner
This commit adds a new model to the Sky Texture node, which is based on a method by Nishita et al. and works by basically simulating volumetric scattering in the atmosphere. By making some approximations (such as only considering single scattering), we get a fairly simple and fast simulation code that takes into account Rayleigh and Mie scattering as well as Ozone absorption. This code is used to precompute a 512x128 texture which is then looked up during render time, and is fast enough to allow real-time tweaking in the viewport. Due to the nature of the simulation, it exposes several parameters that allow for lots of flexibility in choosing the look and matching real-world conditions (such as Air/Dust/Ozone density and altitude). Additionally, the same volumetric approach can be used to compute absorption of the direct sunlight, so the model also supports adding direct sunlight. This makes it significantly easier to set up Sun+Sky illumination where the direction, intensity and color of the sun actually matches the sky. In order to support properly sampling the direct sun component, the commit also adds logic for sampling a specific area to the kernel light sampling code. This is combined with portal and background map sampling using MIS. This sampling logic works for the common case of having one Sky texture going into the Background shader, but if a custom input to the Vector node is used or if there are multiple Sky textures, it falls back to using only background map sampling (while automatically setting the resolution to 4096x2048 if auto resolution is used).

2020-05-01UI: Use property split layout and decorators for material propertiesJulian Eisel
Use the automatic property split layout (hence, change to the new 40/60% split ratio) and add decorator buttons for animatable properties. This actually applies to all node input buttons in the properties, e.g. world shading, light shading, texture nodes. Doing this makes the layout more consistent with other layouts in the properties. But the decorators are also a useful hint for users that these options can be animated. Previously using decorators and the automatic split layout wasn't possible, I've done a number of changes now to have it supported. Before I moved the socket icons to the left side, the decorators also looked weird (two circle icons next to each other). {F8497704} With nested items: {F8497708} Reviewed By: William Reynish, Pablo Vazquez Differential Revision: https://developer.blender.org/D7544

2020-04-20Nodes: New Object and Image socket typesJacques Lucke
Those new socket types will be necessary for particle nodes. The main difficulty with adding these socket types is that they are the first that reference ID data in their `value`. Therefore, user counting code had to be added in a couple new places. Reviewers: brecht, mont29 Differential Revision: https://developer.blender.org/D7347
2020-04-20Simulations: Add simulation node tree typeJacques Lucke
This implements a new builtin node tree type called `SimulationNodeTree`. It is not yet embedded in the `Simulation` data block. The node tree will initially be used for the new particle nodes system. When the cmake option `WITH_NEW_SIMULATION_TYPE` is enabled, a new `Simulation Editor` is shown in the editors menu (which is just a node editor). This patch does not add entries to the Add Node menu, so it is empty. Reviewers: brecht Differential Revision: https://developer.blender.org/D7287

2020-03-09Cleanup: Replace ABS/SQUARE/CUBE with function callsSergey Sharybin
While it might be handy to have type-less functionality which is similar to how C++ math is implemented it can not be easily achieved with just preprocessor in a way which does not have side-effects on wrong usage. There macros where often used on a non-trivial expression, and there was at least one usage where it was causing an actual side effect/bug on Windows (see change around square_f(sh[index++]) in studiolight.c). For such cases it is handy to have a function which is guaranteed to have zero side-effects. The motivation behind actually removing the macros is that there is already a way to do similar calculation. Also, not having such macros is a way to guarantee that its usage is not changed in a way which have side-effects and that it's not used as an inspiration for cases where it should not be used.

Custom render passes are added in the Shader AOVs panel in the view layer settings, with a name and data type. In shader nodes, an AOV Output node is then used to output either a value or color to the pass. Arbitrary names can be used for these passes, as long as they don't conflict with built-in passes that are enabled. The AOV Output node can be used in both material and world shader nodes.

2019-11-25UI: Allow label for Template-ID (respecting property split layout)Julian Eisel
Adds a `text` parameter to `bpy.types.uiLayout.template_ID()` which causes a label to be added, as usual. Adding the label also makes the template respect the `bpy.types.uiLayout.use_property_split` option. Also fixes wrong layout being used in the template-ID, although I think that didn't cause issues in practice. Sergey requested this for usage in the Movie Clip Editor.
