Hi community! Picture: Demo: https://codepen.io/prisoner849/full/qEbEveG The first thought was “let’s build a box of boxes, using InstancedBufferGeometry, but coortinates of an instance will be based in its index”. …

I was using InstancedMesh with custom InstancedBufferAttributes. Then I got to have many of such InstancedMeshs that use the same material, so I tried to use BatchedMesh to draw them at once. But I was getting some inter…
