Hi,
If i use Brute force + Light Cache render perfect, when i change to Irradiance Map + Light Cachet , vray crash Max after light cache calc.
I make a fresh install Max and Vray the problem is the same.
Any sugestions ?
Max 2017 Sp3
Vray 3.50.04
And Another Crash This time with Brute Force + Light Cachet
Does it happen with a specific scene? If yes could you send us the scene to support along with 3ds max minidumb file?
In all scenes, i even make a fresh install of Max and Vray, don’t use any other plugin , max don’t generate any minidimb file..
i just go back to Max 2016 and works fine until now, but have lot’s of scenes and models to save as max 2016 now 
In this case it might be best if you could send us an email to support and we will arrange a Teamviewer session to check that issue first hand. Please make sure to mention this thread in your e-mail.
