LARGE SCENES RENDERING

[idtasos]

what about the 1500 mb limit of the cards memory? any solution ? Can octane render scenes more than 1.5 gb ? Is it true that it cant render scenes heavier than 1.5 gb?

[radiance]

yes, but there are workaround, using procedural textures which take no memory at all.
the 2.2 which will be released in a few days to public users will have this functionality.

if i have 2 GTX470 1280RAM and 1 GTX 280 2048RAM which ram will the system use? will it use all the CUDA cores simultaneously?

[radiance]

you can use all 3 cards together to get very fast speeds, but you'll only be able to use the lowest of the cards , eg 1280mb for your scene.
the scene needs to be copied into all 3 cards.

would two cards like this solve the problem with the memory?:

PNY Tesla C1060, Quadro FX 5800, 4096MB GDDR3

[radiance]

the rule is simply, you can use your GPU's memory.
if you render with more than one GPU, you're limited to the smallest of the GPUs that you're using.
