I recently installed maya 2020 and arnold works fine except this when i open a few car models which use to work with the beta i get this error:
// Error: [polymesh] /group1/HDM_05_003_chrome_noFBXASC045ms/HDM_05_003_chrome_noFBXASC045msShape: incorrectly defined UV coordinates, missing either uvlist or uvidxs //
What is this ive never got this error before. Also i did pre populate my gpu cache but in other scenes too it takes longer than it used to before to get to first pixel. this error that i mentioned above makes the models not work with the cpu or gpu. These models used to work before but they dont anymore.
it seems like it happens in those scenes only i imported the fbx models with no previous materials and they render just fine.
The UVs on those shapes are messed up. MtoA can't get valid UVs to give to Arnold
it used to work before and it still does when i import the raw fbx files. they come from 2018. could that be a problem? i also have a shadow matte error can you help me out?
