Maya Arnold Stuck In Long Loop Looking For UDIM Textures That Should Not Exist

[Anonymous]

My frame will render successfully but the output window / log will keep displaying these image file statistics for ~20 min before stopping - It's impossible to escape out of and will hold up the render farm as it doesn't trigger as complete until it's done.

Normal UDIM textures as follows ( only four tiles, 1001-1004):

xyzReformer_black_METAL_v001.1001.png

somehow triggers it to look for textures in UDIM tiles that don't exist, like 10001. It keeps counting upwards.

Here's a small sample of what becomes a 35 mb log.

[Stephen.Blair]

Hard to really tell from just a snippet.

Maybe it's the UVs?

What if you enable Ignore Missing Textures on the image node?

[thiago.ize]

Like Stephen said, this suggests your UVs are requesting all these other udims. If possible, I'd suggest investigating what's up and see if you can fix that.

But if you're ok with that or it's too time consuming to fix and you just want to speed up the logfile, you can try lowering the log verbosity so that the per texture stats are not shown. I'm not sure how mtoa exposes/sets these options. If there's no checkbox for it, maybe you can go into the diagnostics page and under "user options" add a line that says "texture_per_file_stats false"?

[Anonymous]

Not using aiImage nodes so I don't have the ignore option. Could re-build the shader with them I suppose if that's the solve. There is one object that is crossing multiple UDIMs. Will look into that.

The log is insanely long but here's another piece further along so you can see it's insane counting skills :
