Hi Felix,

Sorry for the delay, had a lot of works this week.
So I have take some time to check your scene, models etc,
and there is indeed something wrong with the shading.



So here a view of the actual model, with vertex on and off.
The shading of the first image is not right according to the lighting.



Now I did a fresh export from MoI with the model you send me, and everything seems right with the vertex map.

So my conclusion, is that at some point during the animation setup, you probably rotate, scale, moved the model, or part of the model, in poly/vertex/edge editing mode.
As Michael said, any transformation in modo has to be done in Item mode, otherwise the vertex map dont match the model anymore.

So I would suggest to redo the setup from scratch. The original .lwo you send me is looking right, but I will probably suggest to tesselate it a little bit higher to avoid
raytrace shadow problem.

Try to match the right scaling in MoI so you dont have to rescale the model in modo.
And really pay attention to only use the Item mode when moving/setuping you scene.

»» Another thing you might try is converting your object to a Modo "static mesh" type object instead of a regular mesh
The problem with static mesh is that you also kill every uv maps, can be annoying to add decals and the like.
