I can´t test the above today since I´m still working in Maya
but allready do most of my personal stuff in XSI (at home) it
would be great to also optimize that in depth once and for all.
The more I have the chance to compare the apps, the less
satisfied I am with Maya, btw. Especially when shading and
rendering with passes in mind. Oh, boy. Additionally, it´s Maya8...
Cheers
