Enjoying the tool so far, thanks for all the hard work that has made it possible.
Quick question - I have a basic geo in Houdini with a VOP moving a few points around, it has normals and UV. I've exported it as a Soft VAT with 2.1 and imported it into a URP scene in Unity, all good. Normals look ok on my mesh in unity until I add the VAT material and then all my normals have gone funky? Why would this be? Thanks for the advice (I'm a total Unity newb).
You can select the brim edge loop and use a Facet SOP. Set group to your edge loop point group and turn on Unique Points. That will split the brim to get better normals. What you were seeing was due to the fact that VAT records data on per point basis,not per vertex basis, so hard edges will be not reflected unless you split the edge.
