  • overexposed areas and artefacts

    hi, i face a view problems in my actual rendering.
    1.) i get too bright areas in shaded regions where the windows hit the walls.
    i only can get rid of that by using override materials for the walls and the windows with quite dark gi material (rgb 40/40/40).
    by using brighter gi materials the overexposed areas return.
    but with the dark gi material i of course get very dark shaded areas...what i want to avoid.

    is there a way to exclude an object(walls) to send gi to another object(windows)?


    2.) the artefacts i solved by rerendering with lower settings - see the image below. can someone declare me why i get rid of the artefacts by lowering the settings?

    For the artifacts, they are caused by the sun; if you make it "invisible" they should go away.

      hi vlado, tried that at first. but with the higher settings the artefacts stay, also when the sun is invisible. they only dissappear largely when i render with the lower settings.
      what can i do about the bright areas on walls and windows?

        I'm not quite sure; it would help if you can send us the problem part of the scene to vray@chaosgroup.com

        Best regards,
