Hi Vlado,
Running latest stable build here with 2012 64-bit.
I can’t pin down exactly when this is happening with any reliability but when I try to cancel a render it often crashes max right to the desktop, sometimes with the bug window sometimes not. Sometimes this happens during LC calc, sometimes during IRMap calc and sometimes during a normal render. It also happens sometimes even the second time I’ve tried to render having let one full render finish.
Something in the back of my mind is telling me it’s something to do with geometry caching or something along those lines… but that’s just an inkling I have.
The only major plugin I’m running is Forest Pack Pro but I have a feeling this has happened to me on projects where I’ve not used Forest.
Thanks,
