How many textures?

[Henrik]

Is there a texture limit in octane 23 v5?

Is there a texture limit in octane 23 v5?

you mean the size of the texture ?
from what i know, there's no size limit, i loaded an hdri of 10000x4300... but watch your gpu memory

I mean how many different textures in one file

[matej]

As many as your VRAM will let you

I think that vram don't count on the numbers of textures, i have scenes of 200mb with about 400 materials and i can't render on octane, my video card support 1,5 gb. The error came from nodegraph not a crash of memory

Hi, I have seen this in a topic some time ago (I don't remember the post), and I noted it on a paper :

Octane Texture limits due to CUDA :

64 RGB 24bit ldr textures : PNG, JPG, etc...
32 greyscale ldr textures : PNG, JPG, etc...
4 RGB HDR textures : openexr, hdr
4 greyscale HDR textures : openexr, hdr

This has to be confirmed by Radiance, but I think that these infos are still valid.

CUDA limits the number of textures (even if they are like 10x10 px)?

That sounds like a serious flaw.

Not at all, it is only a matter of organisation. CUDA limits the number of images used, not the number of actual textures :

You can put several textures on the same image file. Recently, I used a very heavy ground texture of 6000x6000 pixels, but as a big part of this surface is hidden under a building, I used the hidden part to map different textures used by a building present in the scene. So several objects or materials can share one image file composed of several textures. This allow to use more textures than the amount of images allowed by CUDA technology.
