Interesting. I should try using 180 instead of 300.

I found somewhat of a solution to this, at least what helps for me. Use only rectangular lights, STORE TO IRRADIANCE MAP checked for sure, render with irradiance map as primary engine and use as little omnis and other lights as possible because they cant be stored to irradiance map (no option for that). And output file as .exr vrimage.

I stand corrected. Interesting. Has anyone tried either of these?

model as smart as possible and render by "zone render"

I bet you could achieve this effect by rendering a small portion of the modeled material and take than alpha mask and use that as a glossiness map in refraction? Quite the challenge.

Thanks it works !

ah.. ok.. i quick googled it and found the "official reseller" edit: removed the pirate torrent link (sure.. i didn't want to promote it, just kidding.. anyway..)

Well I'm not really sure on a Vray setting side, but in Photography the way to fix that would be by doing 2 or more exposures, one for proper interior lighting and one for proper exposure of the window and then combine them in photoshop or other HDR program.

A cheat if you just need color is to put the color directly on the refraction. you won't get the SSS effect but on box this may not matter much.

Hello thanks for responding. I didn't have the time to work it out so I used ies lighting instead.

There's also this thread that could help! http://sketchucation.com/forums/viewtopic.php?f=80&t=20999

did you make sure the specular map is in the perpendicular slot of your fresnel reflection options? If it is in that location, then glossiness will be affected.

@valerostudio said: The most powerful rendering engine is NOT V-Ray, it's Photoshop! Kind of agree with Valero statement here.. regards, vd

If you are loading a vispot from the internet, I would say thats the culprit. You should stay away from these things because some are from the older 1.05.30 version and there are lots of changes between the 2 versions and will cause errors.

Yep- thats the trick. Right now, its the only way other than figuring out what numbers to use for tiling the bitmap in the parameters. You can do it that way, but the method above will allow you to see the map in SketchUp.

my problem solved! by uncheking "use for glossy rays" in "light cache" in V-ray option

That most likely can be fixed by changing your irradiance map settings. There's an option to "Check sample visibility" that you can enable. You can also increase your "Max rate" to -1 or 0. Lastly, you can increase your HSph. Subdivs to 70 or 90 - which helps with splotchy shadow areas. Worst comes to worst, you can enable Detail Enhancement, but that means longer render times.

Have you tried the Advanced Camera Plugin. See here It might be of use to you. Rob

FIXED! I guess I deleted the plant while batch render was in progress. I just had to stop the rendering process, delete it again, purge unused materials, save and close. When I re-opened the model and did a test render, the plant was gone... hopefully forever. Thanks anyway... hope this can still be helpful for someone Thanks, Ed

@jonedvard said: oh and regarding the spheres. my approach would be to increase the number of segments when creating your sphere - providing a smoother surface. an arc with about 48 segments is what i generally use for a fairly adequate smooth surface. hope that helps! It's called the "terminator" problem @ATLAStudio - good info, thanks! For me, I just keep re-loading a working water vismat, so I didn't remember off-hand which setting it was...
