Help: Werid coloured polys on export from Modo-Max
polycounter lvl 18
Ye, I exported a model from max to modo then back and now the model has some random colored polygons. What's going on? It doesn't seem to be vertex shading or a texture so what else is there?
Deteaching the mesh to a new object fixes it but I'm still interested to know where the information was comming from?

I'm not sure if those are inside out, some look to be gradients? If you click the object, then right click and turn on back face culling do they disappear? If that's the case then you need to flip them either in edit poly > poly mode > select and flip. Or via a script (I think one is up on scriptspot.com).
Make sure there aren't two polys sharing the same space.
Also weld verts with a really low threashold and set your smoothing groups 1.
but since you figured out a way to fixes it, I guess you're lucky
Are you using obj to move your models back and forth between Max and Modo? And if so, when you import your model into Modo are you deleting the "vert_normals" in the "Other Maps" section under the Lists tab for each mesh layer?
That was one of the first things that really messed me up when I first started to use Modo and was bringing in previously made models.
Also if you are using the stock obj importer/exporter that shipped with Modo 401 there is a replacement script available that fixes up some issues.

If you are using Modo 302 there's a script for baking vertex normals get it here:

Might work
