View Full Version : missing FP state params

My ARB FP state params for materials and light products suddenly all return null. The same paramaters work fine in VP and they've worked fine to this day in FP. If I put constants in their place they work fine and so do atrribs.
Any idea what might be happening? I don't know of any dependancies that might result in this.

Has no one really ever experienced this? My FP just isn't picking up any material related state. I've now tried out all sorts of stuff and had a thorough look at the spec, there doesn't appear to be any possible reason for this to occur that might apply.
The strangest thing is that the same parameters come through just fine from the VP.

What's your renderer?

No I haven't bothered with this yet. Are you saying all material states are always 0?
