I'm wondering if anyone has had similar issues and maybe found a workaround: We've upgraded our project to Unity 2018.3 and now have strange render artifacts and glitches, which look like this: Basically, all textures (including render textures) are garbled and flicker in wild colors as soon as a certain number of SkinnedMeshRenderers are present in the scene. This happens when: SkinnedMeshRender count is above a certain number (approx. 40 instances) GPU Skinning is enabled Only Unity 2018.3 (2018.2 works fine) I've investigated quite a while to rule out other influences and only found the actual skinning to cause the issue. In my reproduction project there are no other textures or special objects, only SkinnedMeshRenderers without animations. In my test case I spawn skinned meshes in an empty scene. At the start, everythings works fine, then I spawn more instances and as soon as their count is roughly at 40, the flickering starts. To me, this looks like GPU Skinning is writing data to some vertex buffer and other shaders are reading from the same data or some similar effect. I can work around the issue by disabling GPU Skinning in the PlayerSettings, but for our current project it is basically essential to use the option because of performance limitations. Additionally, we would like to upgrade to 2018.3 because there are other unrelated performance improvements which we would like to benefit from. I've filed bug Case 1109597, but since it may take some time to resolve, I wanted to hear if anyone from the community knows a possible solution in the meantime. Thank you!
