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.
