Does ATI support texture access from within a vertex shader? I’ve written a vertex shader that works fine on nVidia, but I get a “Link failed” when attempting to use the shader with an ATI card (specifically, a Radeon x700 with the latest drivers on Windows). Compiling and linking succeeds if I comment out the line containing texture2D function call.
Forgive me if this has been covered before. I poked around the forums and couldn’t find a direct answer.
