InstancedMesh vs. InstancedBufferGeometry

[Chaser_Code]

Its posible to use several materials like phong, standard, lambert in one shader and one draw calls, but bad solution, because will be very big code and warst fps
Its posible to set different colors, textures to different objects in instancedBufferGeometry and InstancedMesh
For me instancedBufferGeometry is raw solution of InstancedMesh fo custom developing.
For you maybe simple be using instancedMesh
My sprites with 13 textures is instancedBufferGeometry, 1 draw call

InstancedMesh - can it be used to draw hundreds of planes with different textures?

Yes, but it’s hard to map it onto your use case because of the massive amount of different textures. Can you really use 250 texture objects in your app without crashing? TBH, that sounds a bit extreme. I would suggest to merge all textures into a single texture atlas, use it as the diffuse map for a single material. You can then use an additional instanced attribute to define texture offsets per instance. Then, and only then, instanced rendering makes sense. When using InstancedMesh, it’s eas…
