Hi guys,  
I’ve been working on my bathroom image again but getting a lot of noise on the ceiling , any tips ?  
The 2 v-ray lights have sub divisions of 20.  
I’m using Ir map for first bounce and photon map for second and converting to Ir map.  
Any help would be appreciated,

Cheers  
TD

(ps will change background image looks bad)

are you using vray lights at the windows? make sure they have enough subdivisions. If they are portals, then switch them to normal vray lights.

Thanks for the reply Percy,  
The 2 windows do have v-ray lights with subdivisions set to 20 which i thought would be high enough. They aren’t portals and they aren’t saved with the IR map.

Cheers,

is the ceiling reflective?

if so, increase the subdivs in material…
