alignment on a Geforce 3


I created a vertex shader for skinned mesh that works fine in emulation mode (on a Geforce2) but when I try to execute it on GF3, my characters are deformed (like I uploaded wrong matrix in constant) whereas I didn’t change a line of code … Do I need to align (in memory) my matrix that I upload in the vertex shader constant? if so, of how many bytes should I align my matrix?
