For some unknown reason, this barrel I am working does not want to correctly render the lighting if the normal map is applied, except in the blender internal renderer. It doesn’t even appear correctly rendered realtime in the viewport, as shown in this screenshot.
I have tried everything, even completely remade the meshes and normal maps but for some reason the lighting doesn’t match up with the position of the light source. Unless I render in the blender internal renderer. It seems to have a problem with open gl and d3d, because the same thing happens if exported and put into the ogre graphics engine.
Someone please tell me what is going on and how to fix this.
