I get a "Render Failure!!!" message.
Could somenone help me please.

Free VRAM is too low!
Try to decrease polygon counts and use out-of-core for textures.
Use 'render instances' when it's possible.'


I'm on Mac pro 2009 / C4DR18 / Octane 3.06.2 / GTX 980

Thank's !

Hi roinigo,
since you have only one GPU for system/displays. and rendering, the 980 4GB has only 1.3GB of available VRAM, so it is quite easy to have memory error message.
If you add another GPU, you can leave the less powerful GPU for system/display only, and have the whole memory of the secondary GPU for rendering only.
