Hi Performer gurus!

I am a new to Performer so please don't blame me for asking what you might
consider a beginner's question.
I am using pfMorph to implement 3D morphing. I linearly interpolate vertex
coordinates, normal coordinates etc. So far, so good. My problem arises when it
comes to assigning materials and colors to the vertices/faces amd more
specifically to morph them.
To smoothly morph from material A to material B, I need to construct a new
geoset for each frame. Isn't this slow? (I'm implementing real-time morphing).
Isn't there another way to morph materials?
Or should I only morph colors and forget about materials?

Thanks in advance,

Amaury.
