Maxwell Render

Hi I have question about Illumination Layers.

When I render them separately and then merge direct.mxi and indirect.mxi into one. light solution don't math "plain" render.

I tested this on all known "simball" and even "specular reflection is missing.
on V2 demo there is specular but still merged.mxi looks different (more dull) than regular render.

I am not very deep into math and CG forumulas computing so maybe someone give me tip where to find what is Direct and Indirect light in maxwell.
