I have laid out the uv's with a 2 pixel border (see image below):
However when I right out an fbx (3.2gb) in size, SP gives this error:
FBX : Could not create an importer.
Failed to load 3D scene.
FBX : Could not create an importer.
I then try exporting an obj (also 3.2gb in size) and I get this error inside SP:
Failed to triangulate polygon (no ear found). Probably not a simple polygon?
Skipping one or more lines with the same contents
Errors have been found while splitting meshes per UDIM tile:
Mesh 'g' has a vertex in an invalid UDIM tile: 0, 0.
Loading failed
Failed to load 3D scene.
Loading failed
I have deleted as many unnecessary attributes and groups hoping that would help. My uv's are under vertex attribute at the moment but I have also tried promoting to point attribute which messes up my uv's so I ran the 'autouv' process again which worked but the uv's switch back to vertex attribute again:
I have constructed the uv's all procedurally inside houdini using 'autouv' & 'uvlayout' & 'uvtransform' nodes to give all uv's equal 2pixel spacing, with box unwrapping and moved into the correct udims. So there can't be any overlapping uv's, I have tried searching the tiles and cant seem to find any by eye.
Does anyone have any idea of how to solve this issue - I always seem to have problems exporting meshes with uv's for texturing out of Houdini.
Many Thanks
