continuous crashes while rendering

[em3d]

Hi im experimenting a lot of CUDA API "Crashes" with a very simple room scene...
sudenly it give me an Out of memory error, or render session stay blocked exporting some mesh
the scene work, and it was rendered a few times
but when i made some little changes (linking a material)
i can not rendered any more and i spend a lot of time getting those errors....


my config i6800hk + gtx1070 8G + 64gb ram
latest lux buid + 2.91 official

thanks for your help

maybe its a linked material whats its giving the errors
i check material overide and render works,
then i uncked the overide , its start rendering again

i had a lots of materials linked due to pc limitations at office

You are simply running out of GPU ram while trying to render 124,565,410 triangles (!).

Hi im experimenting a lot of CUDA API "Crashes" with a very simple room scene...

124 millions of triangles doesn't sound exactly like a very simple room scene

Do you have some "out of control" subdivision, etc. ?
