Multi GPUs

Hi everyone,

I have two GPUs : a GTX Titan X (12Go VRAM) and a GTX 980 Ti (6Go VRAM).
I'm actually trying to render a huge scene and Octane is using the GTX 980 Ti to cache the scene, and of course, there is not enough VRAM.
Is there a way to tell Octane to use the other one but still rendering with the two cards ?

Thanks !!

Octane has to send all data to both cards in order for the cards to be able to use the data. In Octane, your total VRAM will always be equal to your lowest card.

If you need more room, you can turn on out of core memory in the preferences to use your normal computer RAM as a backup.

in larger scenes, you can always disable you smaller card and just use the big one.
