Vulkan Back-end

Week 202305

Vulkan Back-end

  • Migrated compute test cases to use GPUShaderCreateInfo [d4d4efd3d3]

  • Vulkan: Use guardedalloc for driver memory operations. [D17184]

Week 202304

Texture painting

  • Change approach for manifold meshes as it currently has to many artifacts and limitations. Idea is to replace the vertex based extension with an edge based extension. By doing that we can keep closer to the actual polygons on the mesh. [21eff2c0ac, #104005]
  • Review Support Automasking For Texture Paint [D15298]

Sequencer

  • Add subsampling filtermode to sequencer transform options. Improves quality when using scaled down strips.

Week 202303

  • When using add-ons that use OpenGL should be reported to the user. [D16996]
  • Some crashes when using gpu module. [ff814ec5f6].
  • Attribute list in shader interface isn't updated when using Metal [17042].
  • Review: Fix T103433: Ensure Metal memory allocator is safe for multi-threaded allocation. Resolves crash when baking indirect lighting. [D17018]

Texture painting

  • Fix edge bleeding of non-manifold parts of meshes [D16963]
    • Fix artifacts when mixing multiple source pixels. Issue was that the second source was not found, due to incorrect search radius.
