Octane doesn't render

[Channas]

I am just trying Octane on my scene and can't figure out why viewport doesn't render anything. Is it overexposed or something?

Open console window and check for cuda errors. You looks like have that

actually, yes you're right. What does it mean? I have the latest driver i believe GTX 660ti, 416.94

Not important! See VRAM usage and free amount of that. You're on the insufficient amount of VRAM most likely.

it used up all the ram and failed to render. So, does it mean I can't use octane unless I buy a better graphic card?
