Vray crashing occasionally upon rendering

[mahmoudelgohary]

hello guys , hope you are all doing well =)

 

there is this problem that driving me crazy , i have no idea if am bumping a setting too much or what , now i made a scene , an interior scene not complex at all its still in progress , when i press render 3ds max just stops responding and closes without any msg , or it says 3ds max unexpected error and asks me to send a report to autodesk while its not really a 3ds max problem , and for my surprise someitmes it just works !!

 

it crashed exactly at building light cache , if it went over past the first couble of secs without crashing it won't

 

i downloaded a complete scene tried to spam start stop the render , it never did what its doing in my file , while bumping the settings to the exact settings i have on my own file

 

i've had those crashes on both 3ds max 2016 with vray 3.2 and 3ds max 2015 with vray 3.0.8 (for that exact file)

 

my pc specs are rather on the powerfull side

Are you using multiscatter in the scene?

i have seen crashes right at the time of building lightcache if there is any object in the multiscatter with a normal map in the material. unlink this normal map(usually in the bump slot) and check.

thank you for your reply , no am not using multiscatter at all

 

Update : when i change default geometry from auto to dynamic i don't encounter any crashes but thats only with the scenes i create , any other scene i download and just press render it works flawlessly

 

i encounter the same crash when i do mat override for my scene too

 

but i think auto is way faster than dynamic so i wanna pin point the cause of the problem , anyone has any idea ?
