osmanertasdiken Posted May 15, 2020 Share Posted May 15, 2020 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!

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 Quote Link to comment Share on other sites More sharing options...
