Hello I am rendering exterior scene, and found these splothes on houses. I am using standard vray physical camera with standard parameters. I tried increasing samples in GI irradiance map and light catch, didn't work. I don't know what to do... I included render pictures and my used settings in attachment.

Extra notes:

Lighting system -

Vray sun,

Vray sky,

2 domes: 1 reflections, another diff.

Try to render with only IRR Map + BF and LC + BF to see if this i caused by LC or Irr. I think it is IRR, you have set the subdvs and interp samples to high values but you render at -4 -3 resolution. If you are rendering in low resolution then it can be not enough. Try to render with -2, 0 and see if it helps.

 

Also it can be caused by models, are they modelled originally in 3ds max or they are imported from Archicad in example?
