THREE.js - Cloned and rotated LOD objects - wrong shading










0















I have a txt. file exported from 3ds Max with name of objects, position, rotation and scale.
Secondly I have a javascript initial list of this objects with paths on extern obj. and mtl. files.
From initial list I create a LOD objects that are cloned across my scene according to txt file.
But I have a problem with shading/lighting of these cloned object that are rotated in the scene.



Please do you know what needs updating after I place the objects in scene?



Two clones of same LOD object with different shading

  • Does the bug happen only when you rotate them? Or does the position also affect their color?

  • Only rotation. The same problem is on tops of houses models - facade is back to the sun but top cornice is lightened from below. Correct lighting is only on clones they have default rotation from 3ds Max.I thought that was wrong normal map, but if I turn off normal maps its same.

  • Have you tried using threejs.org/docs/index.html#api/en/helpers/VertexNormalsHelper to see where the normals are pointing? At first glance, it sounds like your vertices are being rotated, but the normals aren't responding nicely to the rotation.

  • Does the bug happen only when you rotate them? Or does the position also affect their color?

  • Only rotation. The same problem is on tops of houses models - facade is back to the sun but top cornice is lightened from below. Correct lighting is only on clones they have default rotation from 3ds Max.I thought that was wrong normal map, but if I turn off normal maps its same.
