Hi guys – I think i found a bug in the Shader Material. I have re-created the bug on this jsFiddle:
Not too sure how/why this happening, but if you use a shader material and use the function ‘dFdx’ the tool crashes.
If you comment this line out:
“vec2 dSTdx = dFdx( vec2(1.0, 1.0) );”,
Then the shader works.
Is there some kind of initialization that needs to happen to get GL_OES_standard_derivatives initialized?
This issue is related to #3140
