Right now i cannot see where things go wrong. I go test a bit more be removing materials. I made object in blender. did soem painting in 3D-Coat. Then imported that back into bledner and export it to Sansar.

It looks fine in blender and 3d-coat.

I did add a light in sansar inside it , because it's much darker then i want. I need to repaint it different anyway.

 

Bit this is how it  looks in sansar. already tried to adjust a few settings in blender.

The problem is the strange shadow lines. i have them on other places in  the object to. cannot see where the could come from.

 I just tried a simple basic grey surface. and there's no shadow.
Think it's best to design with flat colors and avoid PBR, always good for problems. Need todo more testing and learning.

  It looks like a uv problem. Have you checked the uv map before exporting the object from blender?

  I just looked in blender on the UV-map of the stair. It looked fine. i did upload that it looked wrong. It looks in sansar like there's soemthing wrong with a metal setting.

  I do more testing and painting without the metal maps etc. Make things much more easy at this stage of painitng.

  Then maybe its the orientation of the normals. In blender enable the backface culling (shading) to check it. If that's the problem you can recalculate outside or flip the normals. Or you can use a two sided material but its better to correct the orientation.

  Hmm. i expected sansar is going to make a problem of this.
  The faces are all aligned perfect, to the inside. I wanted to test first the painted inside part before i start with making the outside.

  So it could be that sansar is doing strange things because it does not see on the outside a solid wall. But i still need to paint in other way.

  I go test a bit more.

  To me, it looks like the wrong normal map has been applied.

  Try triangulating the mesh, and view how the faces respond. Sansar triangulates all meshes on import (as do most engines), unless they are already triangulated. Doing so beforehand, may throw up some unseen issues.

  Are you using Atlas maps?
