alrawli Posted June 5, 2008 Share Posted June 5, 2008 Is it a physical sky or is it just added in photoshop afterwards? Pretty easy to do in photoshop if its a still. Link to comment Share on other sites More sharing options...
Dave Buckley Posted June 5, 2008 Author Share Posted June 5, 2008 as far as i'm aware its done in max but jeff may tell me otherwise Link to comment Share on other sites More sharing options...
Macer Posted June 5, 2008 Share Posted June 5, 2008 My guess is its just down to the exposure control (probably photographic) + quite a high setting for vignetting, and the position of the camera/sun? Link to comment Share on other sites More sharing options...
mayamax Posted June 5, 2008 Share Posted June 5, 2008 I think Its Easy With Vray .... If you want to do Work in vray.... Link to comment Share on other sites More sharing options...
Dave Buckley Posted June 5, 2008 Author Share Posted June 5, 2008 funnily enough that was in another post i made over on the viz depot, i said something along the lines of this image (the one i have posted here) has been done in mental ray i can find loads of examples where it has been done in vray but i use mental ray so would love to be able to do it in mental ray as well Link to comment Share on other sites More sharing options...
johnvid Posted June 5, 2008 Share Posted June 5, 2008 Sure is a lot of vignetting on that one giving it an almost polarized looking sky, and making it look really cool (don't mean colour temp), but there is banding in the gradient as there's not enough colours for the range of 8bit, would anyone know if this was NOT done with LWF.

Dave Buckley Posted June 5, 2008 Author Share Posted June 5, 2008 this might come across as really daft but what is LWF, i've seen it written all over the place but never explained?? Link to comment Share on other sites More sharing options...
RobNJ73 Posted June 5, 2008 Share Posted June 5, 2008 LWF = Linear Workflow. Explained fairly well here. Link to comment Share on other sites More sharing options...
Crazy Homeless Guy Posted June 5, 2008 Share Posted June 5, 2008 you might want to try messing with these setting in the mr physical sky dialog. there is a similar one for the sun. adding negative numbers in the sky roll out will make it more blue. likewise, adding positive numbers in the sun roll out will make it warmer. not sure if this is the answer, but this combined with adjusting the exposure will probably get you close.

Justin Hunt Posted June 6, 2008 Share Posted June 6, 2008 Drag the mrphysical sky shader into the mat editor. unlink it from the mrshy. increase the saturation and possible drop the multipier. Of cause play with the exposure values, the mid-tones have a big impact for this type of look jhv Link to comment Share on other sites More sharing options...
