Unity Engine Graphics Aug 11, 2022 · I have found that Unity is accumulating these instanced draw calls, and only seems to be clearing them at the same point where Time. Use this function in situations where you want to draw the same mesh for a particular amount of times using an instanced shader. Everything worked just fine! So Jan 27, 2019 · Hi, I am trying to do a custom foliage rendering system in version 2018. DrawMeshInstancedIndirect to render multiple chunks of tiles per frame, but it only seems to render from the last call made that frame. What appears to be happening is that each Unity Shadow pass drawMesh call is using the same indices appendBuffer, instead of the correct one. This means that both calls work differently, given the same parameters. Otherwise, all the information about which submesh to draw comes from the bufferWithArgs argument. It seems RenderMeshInstanced is newer, should I be using it? Is it more performant for some reason? I’ll have to run some tests myself, but any info on the DrawMesh vs RenderMesh apis and why to use one over the other would be great!

I’m trying to render meshes with shader graph shaders from a custom render pass using CommandBuffer. Example: I have tried a bunch of times to write a DrawProceduralIndirect-compatible PBR shader with shadows & indirect lighting support, but always failed because I can’t find any examples or clear learning resources. See screenshots for my model’s default looking vs instanced one. RenderMeshIndirect once with buffer of IndirectDrawIndexedArgs Custom per instance data provided in shader with StructuredBuffer or cbuffer (tried both) → 1 command submit to GPU for ALL meshes → on Vulkan this should be MDI (Multi-Draw-Indirect)? however it seems Sep 12, 2019 · I took the sample from the documentation page and applied a mesh with multiple submeshes to it. Naturally I decided to set the submeshIndex parameter to 0 and see what happened when I changed the submesh index of the example script to 1. The actual draw data to be used is passed by the GPU in the buffer set up as the indirectArgsBufferHandle. Now I’ve written a post processing depth of field shader that samples the cameraDepthTexture. 3. Add a "draw mesh with indirect instancing" command. But from my perspective, it really looks like the bounding box is moving the trees—since if the box is small or centered incorrectly, they vanish or shift.
