This are the Settings I used at last, as suggested by valerostudio: () Set the "Max. subdivs" to 100 (one hundred). Leave the "Min. subdivs" to 1. (Done) () Set the primary GI engine to Brute force GI. Do not change the subdivs. (I left the Irradiance Map option, there was no "brute force" in the version of vray i'm using) () Set the light cache interpolation samples to 5. (I assumed this is called "Filter Samples in the version i'm using, if so, done) [] Noise threshold 0.001 The rest of the sugestions were already set by default. I think the render improved a lot, feel a lot better with the result, i'm posting the image for your critics if possible. Thank you! [image: CExI_COMEDORDA4.jpg] [image: VE4t_COMEDORDA5.jpg]

Hi joseark, Could you post a link with your scene, I'm not sure why its doing that and If I can see how your material was created I might be able to help. Ted

Thank you, i tryed that (change the IES file) and I manage to get more or less what I was looking for, I still need lots of practice for that kind of render (Night Scene, or interior). At this moment (same model) i'm having issues with a glass material, i'll upload some pictures to see if i can get some help, again thank you very much

Very nice of you to ask. The more shared, the merrier, and folks can help more that way as well (with models, renders, etc.). Which is not to say that any help is needed. Makes more sense to me personally now that I can see more - the way it all works physically. Looks very nice, BTW. Whatever you have time for is swell, indeed.

Thank you kingsi! Well i've been working on a scene that i think is finally going the right direction, i still need to polish lots of details. What rendering engine do you use?
