Here's my render: You'll notice the splotches around the door frames. Settings are the typical render settings, set to quite high. IRR set to medium. LC set to about 1500/2000, noise to 0.005, shadow subdivs around 24, actually set Hsph to 100 to see if that would make a difference. Might not be a render issue, might be something to do with the geometry? Anyways, suggestion welcome!

Hi all! I've been having a rather annoying problem with V-Ray and I wondered whether you guys could lend a hand. I am trying to render a simple scene consisting of a plane, a cube and a teapot. All of these objects use a standard VRayMtl with just the diffuse colour set differently for each. The problem is, when using a HDR image for the GI Environment (skylight) override, the render always comes out with large splotches over the floor plane and objects. Also, if there is any animation in the scene, a large amount of flickering and 'glitching' happens around the objects in question. In the GI tab, all settings are left at default with the primary render engine on "Irradiance Map" and the secondary on "Brute Force". I have rendered out the exact same scene twice, using just a Vray Light for the first and removing the Vray Light and using a HDR image for the GI Environment (skylight) override for number two. All other settings are default. As you can see, the HDRi is causing really nasty splotches everywhere. I believe this problem is caused by the Irradiance Map, as using a lower preset causes larger spots, however, since I wish to light my animations with a HDRi, I'd rather keep the render times as short as possible, and using high Irradiance Map settings drastically increases render times. The method I am using with the HDRi is putting the "VRayHDRI" material in the GI Environment (skylight) override slot, instancing that to an empty slot in the material editor and in the VRayHDRI options, selecting the HDRi I am using (http://www.openfootage.net/?p=255). I also set the overall multiplier to 12 in the processing. So, my question is, how can I remove these horrible splotches but still keep my render times realistic? Also, could this be what is causing the horrible flickering and glitching with animations? I have attached the scene file for anyone who might want to take a deeper look. The HDR file I'm using is this: http://www.openfootage.net/?p=255 I'm using V-Ray Adv 2.30.01, 3DS Max 2012 on a Windows 7 machine. Specs (just in case): i7 2600K (3.4GHz) 16 GB RAM nVidia GeForce GTX 590 Thanks very much in advance! VrayHDR Problem.zip

hi, ive got 4 photometric lights emitting from cylinder. when they r out in the open they light up the scene properly. but when they r hidden in the ceiling, they light through the geometry and make splotches as if using low GI settings.. now those images r rendered with FG only on Low preset with 3 bounces..

I've done a pretty decent search for the noted topic and tried a lot of the settings/suggestions given, but I can't seem to get rid of these completely random splotches in my scenes. I've attached some image examples. [ATTACH=CONFIG]47326[/ATTACH][ATTACH=CONFIG]47327[/ATTACH][ATTACH=CONFIG]47328[/ATTACH][ATTACH=CONFIG]47329[/ATTACH][ATTACH=CONFIG]47330[/ATTACH] They're completely random and there doesn't seem to be any rhyme or reason why they appear. I've tried jacking up AA settings, changing reflect/refract values on the materials, making the sun invisible, nothing seems to help. Any help is appreciated.

Hi, so I'm having an issue that I think I resolve every job, but it keeps coming back, and my prior solutions end up not working. I'm hoping that this image I upload will describe it best: [ATTACH=CONFIG]45265[/ATTACH] I am using 3ds Max 9 I am using Mental Ray for rendering I am using Final Gather (settings should show up in the image) I am rendering out a 320x240 pixel image, and enabling the read/write Final Gather Map. After that rendering, I click on "Read Only (FG Freeze)" and render out a 3200x2400 pixel image (these images are usually blown up very large for marketing displays). I do that because I read on this forum a number of times that rendering out a small image with the read/write final gather map, and then freezing it and rendering out a larger image will be fine. What I'm finding is that when I render out the smaller image first, I get these weird dark splotches on the corners of my walls. But when I render out a much larger image first, the splotches are not present. Does anyone know what the deal is?

Hi all, I'm having a lot of problems with splotches. I attached 2 renderings of different render quality, but the result is not good. I usually use Solidrock, but even if i manually increase the settings, splotches are still there. Lighting is done by a dome with hdri in it. It is work in progress, but any critics are welcome. Thank you

As the attachment will show, I am having problems with shadows in my interior panorama scene. Splotches and wierd tints keep cropping up despite best efforts to correct. I have attached my render settings but I think it is either a material or lighting issue. Any advice would be welcome.
