Xnormal error (GOING CRAZY!)
Hi there!
Ok so I am new to normal mapping, I created a low poly mesh in Maya and exported it to Sculptris for ...well...sculpting.
I attempted to generate a normal map via xnormal but keep getting this error message...
"Invalid function parameter 'msh': The mesh default has a UV pointing to a non existent vertex."
What does this error mean and how do I go about solving the issue?
Thanks in advance!

Make sure if you have multiple uv sets to delete any extra ones on your lowpoly before exporting. Highpoly does not need uvs.
I always do a full cleanup.
You can also just do a full cleanup...
1. Merge verts and uv's, check Uvs for overlapping, fix non manifolds, triangulate etc.
Delete history, freeze transforms/xform.
2. If that doesnt work, duplicate your model and combine it with a new object like a Box.
Delete its history and try that...
3. If that doesnt work, export as obj, import it back in, then duplicate it, combine with a box and export again for baking.
Duplicating and combining makes a fresh model..
Exporting as obj, and reimporting seems to flush history
