Hmm. After V5 one of my projects is crashing to desktop when i just try to add a coronaMtl to a Blend Shader ( i am doing this all the time using corona)...
So, i tried this same file on another computer (work) and it worked ok. No problems....
The only difference between the 2 3dsMax installs is that my machine at work had V4 before and then V5 (no daily builds installed) and my machine at home has all the daily builds installed on over another...RC1, RC2, Rc3...RC9...and then Alpha V5...
Is there any relationship ??
