Light source in shadow gives sprinkles effect!

[veej]

I am trying a dusk shot and need some help with light sources that are in shadows.I dont like the SPRINKLES effect that the light coming through the windows & doors is creating. Similarily the lamps do not create a pool of light its more spinkles ( or as another poster called it POINTS!)
Also any pointer to help improve the DUSK effect will be appreciated
thanks

Could you send us the scene? It could be a material thing - its hard to tell from the image alone. Thanks

I had the same problem.

It only seems to happen with light sources I create.

Yeah I believe its probably a side-effect of using our emitters as the sole light sources to scenes. Emissive materials aren't sampled as well as the real V-Ray lights. Fortunately we will be debuting our real V-Ray lights in the next beta release ( due later this week ). That addition should resolve these issues.

Its definitely the home made lights. The more of them you use and the more intense they are the more speckled the image becomes. The despeckle filter in Photoshop helps a bit.

I have also noticed the speckling seems to be the least noticeable on surfaces perpendicular to the light emitting plane. Surfaces almost 90 degrees to the plane are the worst.

interesting - with the V-Ray lights in this upcoming build you should be able to resolve that issue. Sorry we didn't put them in sooner - I didn't forsee the emitters being this much of an issue, but then again I never have tried to use them to light a scene by themselves

I thought it was me, I will give it a try with beta 3 and switch the lights out
