Hi,

I was doing some tests and noticed that the lighting/ normals in my scene differ in the following 2 situations:

1 - 1 big mesh file, exported and rendered

2 - the mesh splitted into several sub objects, rendered one by one

The difference occurs with directional lighting (own engine).

Before digging into normal values etc., I'm curious if someone might have thoughts what could cause this?

Here's an example.

Rendered as 1 big mesh:

Same scene, but now the 'balls' are rendered as individual objects:

With objects rendered individually, the normal map is clearly better (clearer etc.)
