Hi I'm just checking before I delete my code doing fixed function skinning - it's not possible to use pixel shaders with the fixed-function vertex processing is it? I know you can use vertex shaders with fixed-function pixel shaders, which is good for older hardware...can just use software vertex processing :) Chears

Maybe a good solution is to use effect files? have a FF-based technique and a VS-based technique. It should provide a reasonable "base" by which to develop from - if things explode or generally go wrong then you can just drop back to the FF-based technique because you know it works [smile]

neneboricua19, thanks for the reply. I thought I tried using pixel shaders once but didn't work...I always need to do lighting calculations in vertex shaders as you said. Nevertheless I won't delete my fixed-function code - just remove it.

Thanks jollyjeffers, I do use effect files and FF pixel shader fallbacks. In my experinec however, FF skinning is not very practical. Things exploding can be a problem can't they? Hurrah for designing for loose coupling and designing to interfaces!

That's my question answered - cheers and rates
