I’m trying to implement my character skinning code in a vertex shader, but it doesn’t seem to be possible with the GLSL. The problem is, there seems to be a limitation preventing me from using an int as an array index (although the spec specifically says I can do this).
This gives the error : Internal compiler error: unexpected operator.
Am I missing something here, or is this a major hole in ATi’s implementation of glSlang? Is there a workaround for this? Would the same code be possible with Cg/ARB_VP, or is this a hardware limitation that I can’t avoid? Surely it must be possible to skin in a vertex shader.
