Can't export mesh to Maya with UV

Recommended Posts

Hi I'm trying to export a mesh with UV attribute with rop alembic export, but when I import it into Maya I am getting this error from Arnold '// Error: [polymesh] /geo1/uvunwrap1: incorrectly defined UV coordinates, missing either uvlist or uvidxs'

In Maya, I can see that UV's are there though and it works when exported as obj, but I can't use that in order to get motion blur.

Is there any other way I can export the sequence or anyone can let me know how can I fix this?

I attached an example file.

Any help would be much appreciated!

how are you even exporting it? Since apprentice can't export .abc it's not easy to test your .hipnc file to replicte the issue

I literally just selected the 'uv' uvset and copied it over to map1. For some reason, it didn't work perfectly with the displacement textures later on. So I ended up displacing the geo in Houdini as well. If you can upload your alembic I can take a look
