marksee Posted January 23, 2008 Share Posted January 23, 2008 I am finishing up a render currently, and am very happy with one exception. Is there way to lighten up - or make more transparent - the shadows from a vray sun? I would like to do this without changing the global darkening multiplier w/ color mapping... any suggestions? Thanks! Link to comment Share on other sites More sharing options...
diegofer_9 Posted January 23, 2008 Share Posted January 23, 2008 It depends what you are using for environment light and what kind of camera you are using. If it's a vray camera you would play with the exposimeter and f-stop, and depending on what you're using for environment, there's different approaches. Give more details and post an image...

Eric Sosa Posted January 24, 2008 Share Posted January 24, 2008 easy with a pic to judge m8. u can always add standard omnis with very low intensity, with far/near attenuation and still not making the render to look flat. Link to comment Share on other sites More sharing options...
chiquito Posted January 24, 2008 Share Posted January 24, 2008 By pass to the issue: In PS, make a copy of your image (the layer) set it to soft light type of layer. Go to adjustments, and select invert, play with the opacity amount, erase bright areas. This will put some light to dark areas. It might save you some time skipping re-renders. Also render shadows channel separetlly, and compose the same way. Hope it helps. Martin Link to comment Share on other sites More sharing options...
kippu Posted January 24, 2008 Share Posted January 24, 2008 how about using the shadow/highlight option in photoshop ...that will work yes? Link to comment Share on other sites More sharing options...
marksee Posted January 24, 2008 Author Share Posted January 24, 2008 The only problem with that is it is going to be an animation.... I could do an action w/ batch, but it seems like there should be a better way. I could try the omni, I was just thinking that there should be an easier way to do it. I just got the lighting where I wanted it, but I can mess with it a bit more I suppose. The main problem that you will see is the shadows from the trees are very dense. oh, I'm using vray sun w/ size of 20 and intensity .09 and 8 shadow subs... all else is default. Environment is on and set at standard default 1.0 multiplier. Exponential color mapping @ .5 and .5. Um.. what else... Irradiance primary and light cache secondarhy. Think thats it. standard cam.

Ray Posted January 24, 2008 Share Posted January 24, 2008 If you make your sun size smaller it will give you crisper shadows, but that's not a solution for shadow transparency. Link to comment Share on other sites More sharing options...
Eric Sosa Posted January 24, 2008 Share Posted January 24, 2008 dunno, but I always start with vraysun at 0.002/3 intensity and vraycam with shooter speed at 2.0 or standard cam, same sun intensity. kind of difficult for me to start and to use sun intensity at 1.0!!!...then I need to move all ligths and vraysetup to a completelly new enviroment. I must say that I don't have the dark enviroment shadows as in you pic. vray enviromental ligth can not be change by default, but it can be reduced/ligther with some of the above tricks...
