Hey all,
I just upgraded to 2250 RC and now none of my workflow loads due to the following error:
“Texture coordinates of a triangle are indexed to different textures”
I’m a beginner with 3d modelling, using Modo, have no idea how to fix this after banging my head against the wall for a while. I was importing just fine before the upgrade - tried to load previous .objs that worked before and no dice.
Can I downgrade if the fix isn’t obvious to the community? I’m in the middle of a project. Need to fix it in Modo otherwise my layers/etc. will be flattened and my workflow tanked.
Many thanks!
Hi Castlenock
Can you send the OBJ file for inspection ?
ta! Sent you a PM, much appreciated.
Hi Castlenock
The problem is as stated in the error message from RC.
Texture coordinates of a triangle are indexed to different textures

And have done check in Mudbox too

This special case was not checked in the last version. Therefore it imported such a model. However, it would fail during texturing due to this issue. Therefore we will check it in a new version.
Hi Castlenock
One more hint you can try is to use Zbrush to import and export the OBJ to check if it helps in this case…
Thank you for your help!
So to do this in Modo, you need to delete the UVs entirely, recreate them (Atlas projection) and then unwrap [in Modo] the result.
I’m sure there are many reasons to make RC a bit more finicky on how it takes OBJ imports, but from my perspective, I really wish it just let me load the OBJ file as it did before the update. Maybe just throw up a warning rather than preventing me from loading the model at all.
Here’s why: I’m working in Valve’s Destinations, so I’m popping a scene out, working on it in Modo, throwing it back in RC to unwrap and re-texture and see how well my reconstructions is doing as a spot check. I seem to be getting the UV error every time I add a new element to the scene, and now I have an extra hours worth of letting Modo rebuild and unwrap UVs every time I want to see how my changes to the scene took. Unless I find out some button I should be pressing, it’ll add a lot of extra work to my workflow to get to a final product. I’d much rather do the UV remapping at the end of the project rather than with each iteration!
Thanks again for this information - wouldn’t have figured it out this quick without your feedback.

It would not help you very much, as it would highly likely crash during the texturing stage…
The UVs are pain, one of the best tools regarding model cleanup and UVs is Zbrush…
