        Not the most recent one. Question is - is it the very first one?
        If the About section in the Options window - do you see a version number?
        If not - then you have the first one - and with that one you have to use a multiplier of maybe 20000-50000 when you use the Physical Camera.

            Does anybody know why the light of an emissive material appears grainy in space while the light from the vray rectangular light does not?!
            As the photos show, I have created a cube using vray rectangular light with a multiplier of 100, while the sphere is a sketchup drawn sphere, the material of which is an emissive material of an intensity of 50000. The light is grainier when the emissive material is used. Is that how it always is, or can I improve the light quality that is being displayed by the emissive material?!
            Thanks!

                Remissive material is not intended for main light source - merely for the effect.
                V-Ray doesn't process emmissive materials in the same manner as lights.

                  Ok!!
                  So, if I need to create a lamp to put on to a hanging or other lights, should I make a small cube using the vray rectangular light sides?!
                  Thanks!

                    Lots of rect lights will slow down the render.
                    Can you get away with an omni light?

                      What rendering system are you using?

                      EDIT: Ahhh, thanks for pointing it out, Thomthom. My mistake. I just click "view new posts" when I login, half the time don't even know what forums there are unless I post a question.

                        for Thomthom what if you designed an alcove type of ceiling in a room? So you would recommend it to used rectangular lights than emissive lights because as greenlandboy said that emmisive appears to be grainy ? TIA

                          Yes, I always use "real" lights for main light source. Emmissive material only for the effect.
