tanuki1965 Posted February 21, 2007 Share Posted February 21, 2007 Hello everybody, I am trying the vray 1.5 rc3 demo with 3ds max9 and I can't succeed to have a decent sky, I mean there is no gradient colours in my sky .....I tried to tweak the rendering panel but no way ! In my skymap in the material editor I can see the gradient coulors but when I render it's just one colour. I followed many step by step tutorials and I never can get the same "gradient sky look" that result of the tutorial ! Please could anybody post a simple vray 1.5 scene with a plane and a sphere and a vray sky and sun preset ? It would be a great help for me. Thankx a bunch !

antonio_frias Posted February 21, 2007 Share Posted February 21, 2007 Good luck! I posted more or less the same question yesterday and I still haven't recieved an answer. I guess most people are still using the old methods for illuminating exterior scenes with Vray. Personally I use HDRI's alot, they work great.

tanuki1965 Posted February 21, 2007 Author Share Posted February 21, 2007 Yes Antonio, it's very weird that nobody answers. I looked on the net for a vray 1.5 scene to download but I could not find. I just wanna load the rendering presets of the scene and apply the presets to my scene to check what is wrong..I hope somebody will help us. bye.

ericbarlow21 Posted February 21, 2007 Share Posted February 21, 2007 I ran across a short video tutorial from evermotion (i believe)... I will look for the link and repost when I find it I will check shortly to see if I am remembering correctly. I also believe the new evermotion Archexteriors are using the vray sky? i could be wrong... just trying to think of where I mightve seen this used :-P Link to comment Share on other sites More sharing options...
Ricardo Eloy Posted February 21, 2007 Share Posted February 21, 2007 Actually, getting the VRaySky to work is quite simple. Simply check the "Affect Background" option on the Color Mapping and you're set. Link to comment Share on other sites More sharing options...
tanuki1965 Posted February 21, 2007 Author Share Posted February 21, 2007 Thankx for your help Rick and Eric ! I saw a vray html tuto on the Evermotion site and I followed it but It did not work well, still looking for a vraysky&sun scene to download to be able to analyse the rendering presets. Yes Eric, the "Affect Background" option on the Color Mapping is checked, but no way, the sky is still a simple blue shader without nuance or undertones. Take care, Link to comment Share on other sites More sharing options...
jfs Posted February 22, 2007 Share Posted February 22, 2007 Hi Phil, here are to situations done with VRay Physical Camera and a VRay Sun (at 2 diferent low positions) and with VRay Sky in the Environment Map. I made the teapot reflective so the sky gradation coul apear on in a little bit. Are you using the VRay Cam? Max Standard Cam wont take all of the new VRay Sun and Sky, I think (?)! Sincerely, Joao Link to comment Share on other sites More sharing options...
tanuki1965 Posted February 22, 2007 Author Share Posted February 22, 2007 Thanks a lot Jsf ! Yes I use a Vray camera. You render is exactly what I want to achieve ! Would you mind to upload your Vray file so I can render it with Max and check what's wrong ? It would be a huge help for me. Thankx a bunch JSF !

Aaron2004 Posted February 22, 2007 Share Posted February 22, 2007 I had the same problem...the scene is illuminated but the sky looks too dark? If that is the case, the video tutorials on the vray forums can help you out: http://www.chaosgroup.com/forum/phpBB2/viewtopic.php?t=17824 It has a lot to do with Linear Work Flow. The whole video tutorial series is very helpful, but in a nutshell what you need to do (if I remember correctly is this): Instance your vray sky from your environment to the material editor. Click on VRaySky and change it to an output map (while keeping VRaySky as a submap). Toy around with your Output Amount. Of course, the downside to this whole thing is now your scene is overly blue from the sky....the tutorial goes into how to fix this, but it's too hard for me. I ditched the whole sky thing.

Brian Smith Posted February 22, 2007 Share Posted February 22, 2007 Here is a 2 min clip showing how to create a vraysun and skymap. I'm really not sure what you're doing wrong because there's not much to it. You don't have to use a vray camera, you dont have to touch anything in the Render Scene dialog box (except enable GI), you dont need to touch the material editor...you really don't need to do much. http://www.3dasdev.com/vraysun.mov (24MB-may take a minute to load) Link to comment Share on other sites More sharing options...
tanuki1965 Posted February 22, 2007 Author Share Posted February 22, 2007 Thank you very much Aaron and Brian ! I followed the video tutorial that Brian gave and it worked very well ! .... at last ! Thanks guys ! Link to comment Share on other sites More sharing options...
Brian Smith Posted February 22, 2007 Share Posted February 22, 2007 i still don't know what you we're doing wrong before...can you comment. glad it helped. Link to comment Share on other sites More sharing options...
tanuki1965 Posted February 22, 2007 Author Share Posted February 22, 2007 Honestly Brian, I still don't understand what went wrong, moreover I did not change many settings in the rendering panel to make it work...now I need to improve the use of the vray camera settings (even tough If I don't use a vray cam it's working well). Maybe the Vray plane I added made the difference....but I don't think so. I changed the gamma settings too. Thanks to you Brian. Link to comment Share on other sites More sharing options...

Brian Smith Posted February 22, 2007 Share Posted February 22, 2007 Phil, Just my opinion so take it with a grain of salt. I would recommend not worrying about using the vraycamera if you are not at an intermediate/advanced level of work. Obviously it's a great feature, but it's totally not a necessity. Max cameras work perfectly fine and for most people are easier to manage than the vray camera. You're just adding more variables to an already complex lighting program. With Max cameras you dont have to worry about settings that will affect the lighting in your...or at least the way the lighting appears. I would recommend using the vray camera only if you are totally up to speed on all the other main vray lighting controls. With that said, as the Chaos manual states, the VRaySky does give its best results with a VRayCamera, but i would argue the rationale of complicating things for the sake of this.

antonio_frias Posted February 23, 2007 Share Posted February 23, 2007 Brian, Do you now use the vray sun and sky for your exterior scenes systematicaly or do you still light your scenes with vray lights (planes, domes and spheres). What do you prefer? Phil, Just my opinion so take it with a grain of salt. I would recommend not worrying about using the vraycamera if you are not at an intermediate/advanced level of work.

tanuki1965 Posted February 23, 2007 Author Share Posted February 23, 2007 Thank to all of you guys for your advices, especially you Brian. you all helped me a lot, and you too Jfs for your scene. Have a great week-end ! Link to comment Share on other sites More sharing options...
Brian Smith Posted February 23, 2007 Share Posted February 23, 2007 I use a direct light and standard camera for almost everything . The only time i use the vray camera and vraysun is when i'm bored using the same old lighting approach and want to play around with something different.

Brian Smith Posted February 24, 2007 Share Posted February 24, 2007 i'm guessing you already know this, but in case not, you can use the vraysky map without the vray sun. you can use it with a standard direct light for example. Link to comment Share on other sites More sharing options...
siliconbauhaus Posted March 18, 2007 Share Posted March 18, 2007 I'm intrigued by this Brian. You say you dont use a vray camera but you use a vray sky ? I just tried that and everything was blown out from the sky. Would you be so kind as to ellaborate on how you can use the vray sky with a regular camera?

Brian Smith Posted March 18, 2007 Share Posted March 18, 2007 Patrick, i only spent about 30 sec on this but here is a skymap with a standard camera. i can only assume that you have not changed the default 1.0 skymap multiplier that would work fine with a camera that has exposure control (i.e. the vray camera), but not with a standard camera Link to comment Share on other sites More sharing options...
