problems with IRmap

[waaazoo]

Hello,

I have some problems for the IRmap lighting a plane behin some glass. Here is a picture, can't show more.

You see on the left side that everything is ok, but on the left side, the plane, with some (closed) glass on it has no smooth lightmap.
What am I doing wrong ?

regards,

Olivier
