Hey all. I'm trying a tweak to my usual baking workflow. It involves exporting FBX files from Zbrush instead of my usual OBJs. However, the FBX files don't seem to be retaining polypaint info making my polypainted ID map useless. The FBX options in Zbrush are pretty light. Any suggestions on how to get this to work?
Its definitely exporting polypaint data with FBX. Did a quick test with default settings & Marmoset as viewer. Doesn't show up correctly in 3ds Max though.
What happens if you export multiple subtools as a single FBX? Still retains your polypaint? Thanks for looking into this, by the way. Edit : Scratch that. Just tested myself using marmoset. The vertex colour is there. Going to check that Xnormal is reading it properly.
I've been able to replicate your result. Purple polypaint does show up as green in xNormal. Used xNormal's 3D viewer to check. Don't know why. Colors are correct in Marmoset though. Tried different polygroup colors (including white) & that seems to have no effect. Perhaps the RGB values for purple are different in xNormal.…
Got a bit of a weird result with my test. I exported a (polypainted) red cube and a purple cylinder primitive from zbrush. So that's two subtools exported as a single FBX. Made lowpoly versions, UV'd etc. and baked vertex colour in Xnormal. The cube came out red, but the cylinder was a pale green. Same colour as I was…
