Can someone help me whith this?

Heya,

Larger search radius ?
More photons in the estimate ?
Emit more photons ?

I suggest you do the tutorials available to you from your Account - they pretty much explain all the concepts.

As for the corner issue - that's an issue with photon maps in general.

Image it like so... green dots are photons, blue curves are the Search Radius.

Note how there's 5 photons being caught in the search radius.

Now let's move the sampling to the edge (or corner - same problem)

· · · · · (· · · )

Now there's only 3 photons being caught.
result ? the corner (or edge) ends up being darker.

Hope that explains it.

Best regards,
