theres no shadow from top side,i’ve checked " shadow two sided",problem remained,what can i do to solved it,thanks.
This can be solved in two ways:
- Include 2 sides in the material, but the more meshes with such material on the scene, the greater the load on the video card.
- Make the wall thickness in the model at least 10 cm (the most optimal option)
Hello, it’s a little hard to tell from the screenshot, but I think you need to cap the top of the mesh. It won’t make a shadow if there is no geometry there.
