  1. Hello there, I've been having issues with vray lights leaking on the other side of surfaces. I've tried to add an additional interior structure to stop any light from transmitting through as well but it doesn't seem to help. The lights are also not double sided so they shouldn't be illuminating behind them (I think). If you look on the top of the light surrounding the steps you can see it leaking quite noticeably. I added a inner surface to try to fix this. It didn't work however.
  2. Hello, I am trying to render an animation but it's rendering all black. I successfully rendered the light cache and irradiance map, but am having issues rendering the actual video. What is strange is that the material IDs are rendering successfully.I have attached screenshots so you can see what I mean. If you can think of any reason this is happening please let me know! The original model was imported from revit. Vray materials were used to replace the revit materials. Below are the animation rendering instructions that I followed almost exactly, for the exception that I left the light cache subdivs and sample size at 800 and .02 respectively. PART ONE: render > render setup > common > common parameters > time output > check single > output size > change custom > hdtv > 1280 x 720 > render output > nothing checked but rendered frame window > v-ray > check enable built-in frame buffer > vray raw image > check render to vray raw image file > browse to folder > make trash//throwaway folder for this > save as .exr > don’t check save separate render channels > indirect illumination > check “on” > primary bounces > GI engine = light cache > secondary bounces > GI engine = light cache > vray light cache > subdivs = 2500, sample size = .01 > Mode > mode = fly-through > on render end > check auto save > browse to your folder > save in animations folder (as light map) > vray > global switches > check “don’t render final image” output is yourfilename.vrlmap (disregard the .exrs you created) PART TWO: in same max file > rendering > render setup > common > common parameters > check active time segment > every nth frame = change to 5 > vray > vray raw image > check render to vray raw image > browse new trash name.exr > indirect illumination > primary bounces > GI engine = irradiance map> secondary bounces > GI engine = light cache > vray irradiance map > built-in presets > current preset = medium-animation > mode > multiframe incremental > autosave > browse > new file on network .vrmap > light cache > mode = from file > browse > browse to light map from part one (.vrlmap) output is yourfilename.vrmap (disregard .exrs) PART THREE: rendering > render setup > common > active time segment > every nth frame = 1 > can change range if you only have camera at 40 seconds or something > vray > vray frame buffer > vray raw image (one you want to save) > browse to your network folder > save as .exr > check save separate render channels > browse > save as .exr w/ channels > render elements > add vraymtlid > okay > vray > global switches > DESELECT don’t render final image > indirect illumnation > irradiance map > mode = from file > browse to .vrmap from part two
  3. Hi guys, I'm a visualizer working with an interior designer. I recently faced a problem. Company's designer happen to found an image from somewhere (source unknown) now he wants me to follow same light and shadow setup. I've tried many arrangements but cannot figure it out that how this other unknown artist arranged the lights. Also that what was his setting of the material hw applied on wood table as it has light reflection only on corners. Image is pretty crisp too & same time smooth also. In fact its just my guess that he was using vray but im not so sure about it! So any Ideas? Unkown artist's visuals: http://i61.tinypic.com/34oodmv.jpg My typical arrangement includes one or two vray plane lights near fall ceiling, few ies lights near wall & vray plane light out side the window. Regards
  4. Hello everyone Can anybody help me with these issues:confused:? 1. Suppose a scene has a lot of small complicated geometry like lots of cubicles in an office with lots of office stuff in each cubicle. How should I keep the rendering time low & the light calculations minimal esp if it was to be animated? Would Vrproxies help do you think? 2. Lots of vray lights simulating fluorescent tube lights vs vray light material applied to each tube- which would be more efficient render speed wise?
  5. I'm not sure if this post belongs here or in 3ds max http://forums.cgarchitect.com/67449-viewport-turn-black-vray-lights.html#post338001 Hi everyone. I have a problem with 3ds max 2010 64-bit and VRay 2.00.02. My grafic driver are Direct 3D 9.0 (Nvida Quadro 600). The problem is in the perspective viewport when I use Vray lights. It all turn black (as in no lights, only black and grey) when I for example hit ctrl+z or when I flip ctrl+w to maximize viewport. I can however use ctrl+l to switch on default lightning to see lights in my scen but that doesn't solv the problem. When the perspective viewport is black (after hiting ctrl+z, even if the ctrl+z doesn't have anything to do with the lightning) I can click in the perspective viewport and that makes it go back to normal vray lightning. But I have to click in the viewport every single time to make it work. Any suggestions? This problem doesn't affect my renderings - that part works fine! I'm not sure if this problem are caused by 3ds, vray or my grafic driver. But my suggestions are on vray. Thanks!
