Textures on b3d mesh disappears

[gauravjha]

Hi,

I have some 3D building in my scene, which are built as b3d meshes. When the background for the scene is black, the meshes show the original textures, but when the background color is changed, the buildings become white with certain patches on the mesh take the background color?

Can someone explain what can be the problem and, if possible, the solution to it as well.

Regards,
Gaurav Jha

Have you enabled blending?

[gauravjha]

No. I haven't enabled blending. is it required?

[mongoose7]

No, but if lightening the background also lightens the objects, it looks as if the background colour is being added to the object colour.
