reflection planes exclude from FG

[kippu]

i am trying out MR for the first time ...just to make myself learning , anyway is there anyway to exclude some planes i keep in front of the glass as reflection planes ... and to exclude them from FG ....they are invisible but they are getting up in the calculation and darkening the walls in front of them... so any help is appreciated

There are two ways, the first is to hide them during the FG calculation phase, remeambering to save the FG to disk. Then Freeze the FG, unhide the planes and rerender

 

The other in to down load the ctrl_rays shader which has the ability to exclude objects from being calculated. I have never used these shaders myself but the are good.

 

I would suggest using option 1 whilst you as still learning.
