Hi Damien,
It happens with medium/big projects.
When I try to send a crash report, most of the times it doesnt work.
In my last test my PC rebooted twice.
I made a clean install of windows twice and Im pretty sure that it is a hardware problem.
I downloaded a software to see temperatures and my processor is kind of overheating I think (i7 3370k reaches 72º Celsius or 345,15 Fº for a moment and substance crash),
Does substance painter use the processor at full performance when baking? or it just uses the GPU ?
Thank you very much
