TruForm & Vertex Blending

[pav]

hi everyone...
i'm coding in OpenGL and i think i saw something somewhere saying that Hardware Vertex Bleding (using ARB_vertex_blend, not vertex shaders) and TruForm do not mix...is that true? if yes, why?

also can any of you guys help me out doing the vertex blending? i know how to blend the vertices by myself (i.e in software mode)
but i don't really get how exactly i should use the EXT_vertex_blend
what are the 4 matrices for?

thanx for your help.

I reported a bug with it not too long ago... Haven't checked it out in awhile, but TruForm and Vertex Blending should work fine.
