is your geometry multi-indexed? If yes, you also have to adjust the
index mapping, so that the i-th index value is used as offset into tex
coords 4:
MFUInt16 *im = geo->editMFIndexMapping();
// i-th index does not apply to tex coords 3 any more
(*im)[i] &= ~Geometry::MapTexCoords3;
// i-th index now applies to tex coords 4
(*im)[i] |= Geometry::MapTexCoords4;
If that is not the case, can you provide more information about your
geometry or do you have a small program that demonstrates the problem?
Can you give more details on what happens when it is "not working"?
Cheers,
Carsten
