I’d like to change the opacity of some of some of the instances in an instancedMesh by their indices.
instancedMeshes[i].opacity = 0.1 will throw an error:
Uncaught TypeError: instancedMeshes[i] is undefined
In the official doc, there is only the method to change material color by instance index, such as:
But it’s not mentioned on how to change other properties of the material assigned to individual instances.
