Light passes trough some faces of geometry

Jurgolinho · Jul 2016

I get this wierd effect and don't know what's causing it.
I've made this crate in Maya and exported it into unity. In Maya, when I put directional lights everything seems fine, my normals are all looking good, and I have no idea.

All help appriciated.

Try reducing the Normal Bias on your sun, that should fix it!

I fixed your image for you. Just right-click on your image and copy the image URL, then click the Attach Image button and paste it in. This is the button:

You can also just drag-and-drop an image right into your post if you want.

Well thank you very much! Lowering the Normal Bias in unity did fix the problem.
Is it known what causes this kind of light leak ?

The Unity docs explain this pretty well.
