Eric Sosa Posted February 7, 2008 Share Posted February 7, 2008 hey everyone. I'm trying to improve my vray skills and have tried to work with volumetric ligth & vray, but it seems to me that they do not talk together very well & got this conclusions. volume ligth: - can not be used with vraysun - can not be used with vrayshadows - can only be used with standard & photometric ligths volume ligth & shadows: - can only be used with shadow map or the volumetric ligth effect does not work. two examples....(the church was downloaded from the net, created 4 walls around and used for this test) [ATTACH]24532[/ATTACH] [ATTACH]24533[/ATTACH] hope people here can open my eyes to a better ligth volume effect or .....either confirm my conclusions btw...I hate using photoshop to cover lack of 3d skills....sorry Link to comment Share on other sites More sharing options...
Ricardo Eloy Posted February 7, 2008 Share Posted February 7, 2008 Well, Eric, that's pretty much it. VRay lights (any kind) can't use the volume light effect, and even VRay shadows won't work. You're doing it right. Link to comment Share on other sites More sharing options...

Eric Sosa Posted February 8, 2008 Author Share Posted February 8, 2008 forgot to thank you Rick...cheers. but still, is there a way to make something alike the max "volume ligth" effect with vray ligths/materials?. I'll try to find out if a vrayligth/material can be "partialy seen" and still give a volume ligth effect...it would be a great help to do that.

Ricardo Eloy Posted February 8, 2008 Share Posted February 8, 2008 What I do is use a regular light, only excluding everything from being lit and casting shadows (except the thing I want to affect the shadows, of course). Link to comment Share on other sites More sharing options...
hippiearchitect Posted February 20, 2008 Share Posted February 20, 2008 when i try to use volume light effects with standard light is max 2008 with vray 1.5 my max goes all haywire and i have to quit max in order to get it to act right again. and it still does not render, just a black image is all i get.

CRD Posted February 20, 2008 Share Posted February 20, 2008 Have you tried searching on the vray forum for volume light? I remember reading a quote by Vlado where he says that volume light is working, but becuase of the physical simulation with the sun and vraycam, you have to crank up the effect of the volume light to notice it's effect. Basically, it's there, but it's too faint to notice. I could be wrong, but that's from memory. Link to comment Share on other sites More sharing options...
blowback Posted February 20, 2008 Share Posted February 20, 2008 Hey Eric, http://evermotion.org/index.php?unfold_exclusive=145&unfold=exclusive Try this. It's a little compositing trick to fake volume lights. It's not perfect but with some experimenting you can get some ok results. I did this a while back using the techn. It's nothing crazy but you get the idea Link to comment Share on other sites More sharing options...
Eric Sosa Posted February 21, 2008 Author Share Posted February 21, 2008 thx Chris . great floded warehouse render...very artistic. yep, I had seen the tutorial myself and even tried, but my main idea was to get the volume ligth to work with as little photoshop help as posible, and still get the GI to help on making it very realistic. I'm aware of the standard max volume ligths limitations...now , however I'll try to use it in the future. still, I'll tr to see if I can use a vraymat with selv lumination to be use instead...just haven't have the time to try it yet. @ hippiearchitect; it works, but it is completelly sensitive to adjustments, as I said before, the source of ligth HAS to have a very low intensity and it has to be done in an locked enviroment (inside boxes, no planes). I like the effect...check this [ATTACH]24736[/ATTACH] kinda nice, but still it can be done better...I beleive Link to comment Share on other sites More sharing options...
blowback Posted February 21, 2008 Share Posted February 21, 2008 Eric I know.....the less post volume the better. Keep posting. If you find something that works.....POST IT! I wish vray had a volume light. Link to comment Share on other sites More sharing options...
CRD Posted February 21, 2008 Share Posted February 21, 2008 Sorry, I went back and researched my reference and that thread was talking about using Fog for atmospheric persective, which does work provided you use a VRayColor map pumped up to about 385 in Environment Color Map slot. For volume lights, Vlado says: "Would be best to render the volume lights separately; the 3ds Max volumetric lights do not work with HDR colors and so they will always appear too dark with the V-Ray physical camera. On the other hand, we are working on our own volumetrics. Best regards, Vlado" So composite for now and wait for VRay volumetrics down the line.
