  • Rendering black with the exception of area light?

    Hello, I haven't used Vray in a while and today I downloaded and installed the latest version from chaosgroup. I then downloaded the 64bit Windows version of vray/blender posted on this site by Tinmanjuggernaut I am finding that all of my renders are coming out pitch black with the exception of the area light, this is also occurring with Bdancer's 32bit custom build. I get no error in the console but I get warnings such as Unknown property "dispersion" in object BRDFVrayMtl_materialyellow. Any suggestions on how I might resolve this issue?

    Sry, I don't understand what that mean. Post some screenshots.

    This just mean you have an vray that doesn't support dispersion (it was introduced in 2.0), this cant cause black render.

      What render settings? Do you get the same results with GI on or off? What if you use GI plus an HDRI to illuminate the scene? Post a compressed blend file and the console readout.

        Hi guys, this scene is the basic cornell box from this site with default settings. When I render using a hdri it is visible in the render so it seems to be only the models which don't show.

          seanser, don't you forget to press "Export meshes" (http://github.com/bdancer/vb25/wiki/Usage)?

            Ahhh , I did say I haven't used it in a while, how I missed that big button beside render image I don't know! Thanks Andrey, sorry for bothering you with idiocy.

              seanser, no problem =) you could also try "Auto meshes" option in Exporter panel.
