Why do I find these light circles in my final render scene ?

[adamsayash]

I have two problems and I think they're a result of my render parameters:

 

(1)- Light circles ( may be because I didn't exclude the white curtains from the light? may be reflected due to the Chandelier crystals? )

(2)- The edges are not sharp and noisy!

 

-- I have attached the output renders + my render parameters --

My machine is Dell XPS core i7 + 4GB RAM + 2 GB Nividia..

 

Thanks!

Turn off reflective/refractive GI caustics and see if that helps?

 

To be fair your light cache settings are ludicrously low (especially given that there generally isn't much time saving to be had from low light cache settings)

 

Also your irradiance map settings aren't generating many hemispheric subdivisions, so try increasing that and the interpolation samples too. This should produce a smoother result.

 

You're also using the adaptive subdivision sampler which is a legacy mode, it's not been recommended since I think v1.5.

 

In fact in general all of your settings are a bit weird. Read the VRay manual.

Even though he is doing great job with this low setup. You just need to increase your render setup. nice camera view point btw.
