Looks at first promos, looks at CC, looks at Promos again, looks at CC again, looks at more promos… CC starts sweating under heavy gaze, “Um.. I should be ready for a fast burn when it goes live, right?” Nods at CC in knowing way, CC whimpers….
One problem we have with Sprawl 2 in Octane is that you can only load partial sets without removing (a lot of) bump maps. (there are over a 100 different texture maps in that set)
Is it possible to keep in mind to minimize the number of texture/bump map sets?
Octane needs to have all its textures and bump maps in VRAM and has a limited number of texture slots.
Octane is a great and extremely fast render engine, but it comes at a cost…
As far as I have found out the max texture dimension limit is 65Kx32K for Cuda v2. A more practical limit is the actual size of the VRAM where it has to fit and share with all other textures. In practical terms most CUDA cards have 2,3, or 4GB on board.
For US2 the VRAM size needed was not the problem (240MB), but the number of rgb texture maps (100) and grayscale maps(86). For a 600 series Cuda card the limits are 144 and 72, For a GTX 580 it is 64 and 32 if I recall correctly.
So if the number would be cut by half or even lower by combining them, that would be great
