Ah yes, i was fiddling indeed! I changed to 16 bit precision on everything but the displacement but I've put it back to 32 bit now. I'll see if that helps once I get past the next issue.

I've just set things up in a fresh scene, new nodes sopimport/baketexture nodes and getting the same issue as before, things are fine at 4k but break at 8k. Written out to disk and viewed in nuke*

8k


4k


The sopimport contains an alembic > convert to poly > transforms > output

Anything I may be missing here?

Cheers for the help so far

Dropping the vram to 50 solved it! Even going up to 16k now without issues.

I do however have a follow-up question. It seems like going from 4k-16k I'm not actually seeing any quality difference to the content, its just being saved out in a higher resolution.



Am I missing something here? Setup wise its mostly just fractal noise / bake geometry textures / triplanar projection.


Looking into the graph I can see the noise improving in resolution, so I was wondering if the geometrytextures or triplanar was the issue. I've noticed on the bakegemoetrytextures that changing resolution seems to have a drastic effect on the output:

4k:


8k:


Maybe this is causing an issue to some degree, or maybe its just a display issue going above 4k?

Hi there,

Been using cops, loving it, really nice to have this in houdini now.

One question though, i want to render out at 8k, I'm currently setting the default resolution on the copnet to 8192x8192 and the default pixel scale to 4 - that way i can work away in 1:4 proxy just fine and export out in the ropimage_output at 8k (changing to pixel scale 1).

Is that the correct method? Right now things bake out almost instantly in 4k but going to 8k destroys my machine and I'm yet to get an output without it crashing.

Machine spec is pretty beefy: rtx4090, 256gb ram, 64 core threadripper etc

Should I be doing things not on GPU for export? Is that an option?

Cheers!
