Suggestion: DXT textures

[sam75]

Since we are all very limited by the amount of gc ram, would it be hard to add to octane an option to use dxt textures and set the resolution based on distance to the camera ? It could save lot of memory no ?

unfortunately cuda does'nt support using DXT compressed textures at this time.
we're hoping that nvidia will add this to future cuda tookits.

Then what about octane using a temp folder in which it would create itself lower versions of the same texture and uses only the one it needs based on camera distance ?

because octane is not a zbuffer/REYES or scanline renderer, it needs to fire rays at every possible triangle in your mesh.

Sorry I don't know anything about coding I am not sure to understand what it has to do with textures resolutions

What I said could be done by hand when optimizing a scene for octane but it is time consuming so I was hoping it could be implemented directly to octane.

Perhaps added to max2octane script instead ?

Nope, it doesent work that way, sorry.

for now i think a user need to make sure he does'nt waste large chunks of memory on stuff like small objects far from the camera.
we might add things to dea with more optimal memory management in the future, but as an artist you need to be a bit clever to make use of the resources you have, if you don't have much. (and i think making something great with little resources is ever nicer than making something great)
