Invalid normal index.

KoldIt

So I´m doing a school project and need to import an obj file that was made in maya into 3ds max2011. But after I specify what I want to import I get this error, "ERROR - invalid normal index". If anyone has had this problem and been able to solve it then I would be grateful for tips.

Can't say I've seen that one, google didn't help much.

I'd take a copy of the .obj into notepad and delete all of the normals data section. (typically prefixed by vn, sometimes n)

Transferring an OBJ from Maya to max can be finicky. I would suggest exporting as an FBX file. It still has it's own issues but is much more stable than OBJ.

Did you try the Auto or Faceted Normals setting in the importer?

This happens for me, after I imported the FBX files into 3ds Max 2013. It's giving me strange fallout shadows on my mesh. Right in that scene I converted it into other editable options, then it fixed the "...invalid normal" error. But now it render the texture black.

Maybe it's just me, because I thought the polygon got flipped...

Is there a relative index option on the obj import?

OBJ supports negative indices. I know there's an option on the exporter for that in Max, there might be one in the importer.

Just shooting some ideas:
in Maya,select your model,try to unlock all normals,then export with normals ticked,as obj if you wish.
See if that helps..

If not,have you got both packages installed on 1 machine?If so,try booting up Maya ,then 3DSMax,and load up your object in maya.Then Go: File-->Send to 3dsMax-->as new file.

The Auto option in the obj import settings, under Normals, worked for a file I exported from Unity and had that issue.
