Um, we still need the fix in the renderer for the other materials, right?

[sunag]

I think so. After the first compile, define needsUpdate = true is indifferent to customize a diferente shader using onBeforeCompile. programCache.getProgramCode( material, parameters ) returns always the same value without this fix in this case.

This only works because of it:

three.js/src/renderers/webgl/WebGLPrograms.js

Line 249 in 7fe9a41

array.push( material.onBeforeCompile.toString() );
