2020-10-09Revert "CleanUp: Introduce `eMeshBatchDirtyMode` enum"Jeroen Bakker

2020-10-07Fix T81254: Incorrect calculation of EEVEE Transmittance VolumetricsJeroen Bakker
Regular rendering uses a custom blend mode, but render passes renders to 2 separate textures. This wasn't configured correctly inside the fragment shaders. This patch adds a switch to configure the fragment shader with the correct attachments. Backport to Blender 2.83.

2020-10-07UV/Image Editor: Overlay PopoverJeroen Bakker
The overlay options in the image/uv editor is hidden in side panels and menus. Sometimes this panel is even hidden, while still useful. The goal of this task is to introduce an overlay pop-over just like the overlay-popover of the 3d viewport. Popover has * UV Stretching (only available in the UV mode, when active object mode is a mesh and in OB_EDIT mode) * Display As (only available in the UV mode, when active object mode is a mesh and in OB_EDIT mode) * Show Modified (only available in the UV mode, when active object mode is a mesh and in OB_EDIT mode) * Show UV Edges (including opacity slider; available UV, View, Paint, when active object mode is a mesh and in OB_EDIT mode) * Udim tiles when no image is available. Like the 3d viewport, there will be a editor toggle to enable/disable the overlays For compatibility reasons the RNA properties are added to both the `SpaceImage.uv_editor` amd `SpaceImage.overlay`. On DNA level they are still stored in the SpaceImage. only new properties are added to the SpaceImageOverlay struct. During the next major release we could remove these options from `SpaceImage.uv_editor`. This should be noted in the Python section of release notes.

2020-10-07CleanUp: DrawManager Balanced alloc/free of surface_per_mat cacheJeroen Bakker
The alloc was done in the init, but the free was done in the discard. As discarding can happen more often there were some unneeded if statements to work around use after free. This patch moves the free to the `mesh_batch_cache_clear` and removes the if statements to check for use after free.

2020-10-07Fix T79184: Specular highlight turns object black on some studio lightsClément Foucault
This case was leaving some data uninitialized, producing some NaNs in the fragment shader.
2020-10-06Fix T81459: Memory Leak Cycles Rendered ViewportJeroen Bakker
The external engine in the draw manager wasn't registered correctly. This did not free the resources after the external engine was used.

2020-10-01Fix T81268: Crash when undo from Sculpt Mode to Edit ModePablo Dobarro
This was introduced in 6c9ec1c893f9. The overlays can now be drawn when PBVH drawing is not enabled, but the PBVH should still exist in the SculptSession in order to draw them. Before, it was avoiding the crash by checking use_pbvh as BKE_sculptsession_use_pbvh_draw also checks if the PBVH exists.

2020-10-01Volumes: support lower resolution in viewportJacques Lucke
The adds a new option to simplify volumes in the viewport. The setting can be found in the Simplify panel in the render properties. Volume objects use OpenVDB grids, which are sparse. For rendering, we have to convert sparse grids to dense grids (for now). Those require significantly more memory. Therefore, it's often a good idea to reduce the resolution of volumes in the viewport. Reviewers: brecht Differential Revision: https://developer.blender.org/D9040 Ref T73201.

2020-09-29Volumes: support selection and outlines in viewportJacques Lucke
Previously, one could only select a volume object in the outliner or by clicking on the object origin. This patch allows you to click on the actual volume. Furthermore, the generated (invisible) mesh that is used for selection is also used to draw an outline for the volume object now.

2020-09-25Fix T81126: Assert going to Texture Paint workspace without a UVMapJeroen Bakker
Assert happened as it could not create uv batches without an UVMap. Solution is to only request those batches when the UVMaps are available.

For the self overlap result, each intersection pair does not need to be tested twice.
2020-09-22Fix T81026: Image Editor: Alpha (like Bloom) not showing properlyJeroen Bakker
With the new image editor drawing there were was some mutual exclusive functionality. When rendering the alpha was shown correctly or the pure emissive colors were shown correctly, but never both. The cause of this is that the image_gpu did not used the correct alpha mode when generating gpu textures for non-images (render results, compositors viewer) The implementation always checked the alpha_mode. Alpha mode is an attribute for images, but aren't set for non images. This patch adds a more detailed check to ensure that the gpu texture is premultiplied. The issue has been tested using several bug report files and production files. Reviewed By: Brecht van Lommel Differential Revision: https://developer.blender.org/D8978

2020-09-19EEVEE: Add support for GGX Multi-scatterClément Foucault
Based on http://jcgt.org/published/0008/01/03/ This is a simple trick that does *not* have a huge performance impact but does work pretty well. It just modifies the Fresnel term to account for the multibounce energy loss (coloration). However this makes the shader variations count double. To avoid this we use a uniform and pass the multiscatter use flag inside the sign of f90. This is a bit hacky but avoids many code duplication. This uses the simplification proposed by McAuley in A Journey Through Implementing Multiscattering BRDFs and Area Lights This does not handle area light differently than the IBL case but that's already an issue in current implementation. This is related to T68460. Reviewed By: brecht Differential Revision: https://developer.blender.org/D8912

2020-09-18Overlay: Fade Inactive GeometryPablo Dobarro
This implements a new overlay that blends the bakground color over the objects that are not in the same mode as the active object, making them fade with the background. This is especially needed for sculpt mode as there is no other overlay or indication in the viewport to display which object is active. This is intended to be used with D7510 in order to have a faster workflow when sculpting models with multiple objects. Reviewed By: fclem Differential Revision: https://developer.blender.org/D8679
2020-09-18LookDev: Lock HDRI rotation to ViewPablo Dobarro
This adds an option for the HDRI rotation to follow the view rotation. When this option is enabled, this allows EEVEE materials to be used as matcaps for sculpting and painting. This has an extra performance cost when orbiting around the model as the lookdev cache needs to be recalculated, but in my test it is barely noticeable.

2020-09-18GPencil: Implement Holdout materialsAntonio Vazquez
This new feature allows to use the strokes as an eraser of any stroke below. This is very handy to open holes in filled areas. After running some tests, we have decided to keep the additive effect of the holdout color. To get clean holdout areas, just move the color to black to remove any additive effect. To have additive effect can be used in situations like tint slightly a transparent window with blue to simulate the glass.

2020-09-16Cleanup: use uint8_t for various flags in curvesJacques Lucke
Previously, it was kind of a mess. In different places it was using `char`, `short` and `int`. The changed properties are flags that are operated upon using bit operations. Therefore, the integer type should be unsigned. Since we only use 2 bits of these flags, `uint8_t` is large enough. Especially note the change I had to make in `RNA_define.h` to make this work.

2020-09-15Image Editor: Make Rendering of Pure Emissive Colors OptionalJeroen Bakker
There are some areas that don't handle pure emissive colors well. For example erasing alpha using 2d or 3d painting. Or blurring an image in the compositor. This patch makes the rendering of pure emissive colors optional. In the side panel of the Image editor it can still be enabled when needed. There currently isn't a better place to store it as it is related on how the image (or a layer of the image) is created. A future design needs to make sure that the full workflow is supported.
