Crowd Animations works by baking the bone data of animation clips into a texture and reading that texture in Compute Shaders to feed skinning data to the rendering pipeline for indirect skinned-mesh instancing. Introduction. My current idea has been to associate grass matrices with the tile beforehand by raycasting and storing a List<Matrix4x4 []> on each tile. While it was possible to get instancing working partially in 5. Main issue with it is animations callbacks. You can tessellate or do anything else you would. Also, other available solutions for GPU Instancing (including Unity's material option and the DrawMeshInstanced method) fail short on limited buffer sizes and therefore result in more draw calls and less performance. DrawMesh, this function draws meshes for one frame without the overhead of creating unnecessary game objects. 1. Platform compatibility.

Unity only batches GameObjects that share the same Mesh and the same Material in a single GPU instancing draw call. This is useful when you want to render very large numbers of objects that are all the same (with small variations done in shader, like different colors). GPU instancing is one of my favorite batching techniques because it works with non-static objects. I mean moving attached to bones objects and excuting some code during anmiaton playbacks. I was wondering if either the LW or HD pipelines will have any enhancements to instancing--in particular, whether it will be possible to reap the benefits with skinned meshes. When add to characters that have not skinned mesh renderer to scene, system batch them and draw one time all characters. 5 on will now only officially support Unity 2019. Finally, we can pass different frame number f to each instance to render skinned-mesh with animation in one draw-call. EDIT: To clarify further, my skinned meshes have some colours that I'd like to remain constant and some that I do not, and I deal with this by offsetting the texture coords such that the colours I want unchanged are still within the texture region of the same colour while GPU instancing. 试了一下直接超出了Unity的顶点Index数量限制, 所以放弃, 再说转换完后也不方便编辑.

Unity 4 gives you script access to the output from a skinned mesh renderer, so you can precompute animated poses, or cheaply render multiple instances of a mesh in the same pose. To create variations, modify your shader scripts to add per-instance data (see next section to learn more about this). If all your meshes use the same material, ‘GPU Instancing’ is ticked, your shader supports instancing, lighting and You can use GPU instancing to draw many identical objects with only a few draw calls. RenderMesh, but is more performant due to the use of GPU instancing.
