I have read this quote a couple of times:
Quote:What does that exactly mean? If I am passing several TEXCOORD semantics to a vertex/fragment program I need to pass the same amount of samplers right? But how does the programm distinguish the samples since there is no semantics bound to them. Or is it that simple that using sampler A with TEXCOORD1 invalidates it for all other TEXCOORD variables. (I know that this applies only on basic profiles)
basic fragment profiles can only sample a given texture unit with that texture unit's corresponding texture coordinate set
