documentation for Material.needsUpdate

See original GitHub issue

The current docs for Material.needsUpdate say

.needsUpdate : Boolean

Specifies that the material needs to be updated at the WebGL level. Set it to true if you made changes that need to be reflected in WebGL.

But AFAIK most material parameters don’t need needsUpdate set? Is it documented anywhere which material parameters might need needsUpdate set?

So l just thought I’d add the majority of properties for which you need to set needsUpdate are properties that are unlikely to change at runtime.

skinning, useVertexColors, morphTargets, are all things that rarely change at runtime. flatShading seems unlikely to change at runtime. The other big one is any texture input map, bumpMap, normalMap, envMap etc if they change from null to Texture or Texture to null. But that’s also a rare case.

Maybe the docs could say that rather than listing all the cases? It would be nice to know that it’s only exceptional cases where needsUpdate is needed.
