|---|---|
| GraphicsBuffer | The skinned mesh vertex buffer as a GraphicsBuffer. |
Remarks
During motion vector rendering (used for motion blur, temporal anti-aliasing, or other effects), skinned meshes that have SkinnedMeshRenderer.skinnedMotionVectors on alternate between two GPU vertex buffers. You can access the GPU vertex buffer for the current frame using SkinnedMeshRenderer.GetVertexBuffer, and for the previous frame using .
GetPreviousVertexBufferYou can use this method to access the skinned mesh vertex buffer for the previous frame in a ComputeShader. To do that, first request an appropriate buffer binding target via SkinnedMeshRenderer.vertexBufferTarget, then get the graphics buffer using , and then set it up as a parameter for your shaders using SetBuffer, Material.SetBuffer and similar methods.
