Hi,
I'm Stan, I'm a studiant doing multimedia.
I'm doing my final project of university and I encounter few problems.
I'm using VRay 1.47.03. and when I do a rendering with a global lightening, I have no problem, but when I use photometric light with a file IES with a "web" file, circles are drawn randomly on my objects.

Here's an exemple without interior lightening (only with "IES Sun" and "Skylight") :

Here's the same picture with interior lightening:

I've never had this problem without lightening and I have always had it randomly when I use light. Is it due to the fact that I use "web" type lights ? or is it due to the VRay version ?

And I only have this problem when I use "Irradiance Map" et not "Quasi-monte Carlo" ...
But "Quasi-monte Carlo" takes far more time ...

The only way for "Irradiance Map" to work et to put the parameters very high but then my picture takes nearly 9 hours to render, and I've heard that it's possible to render an image in 10 minutes with VRay.
Just for information, I use standard presets et i put the "HSph subdivs" on 20.

Thanks a lot.

Stan.

i think your interior lights are too bright. it's look like ~250-300W each! i think that spots on the floor is overbright. look in vraylog window. is there some warnings?. to solve this problem descrease light power ~2-3 times.

I believe I know what the problem is, but you should go to ChaosGroup.com and use the forums to ask this question. Show them your video, theyll help greatly, may even help you with some material setting issues too.
