F J Posted July 16, 2008 Share Posted July 16, 2008 hi, i got a normal exterior scene w/ vraysun.. im currently trying to come up with a nice patch of grass using vrayfur but its coming out kinda dark.. using vray object properties n crankin' up the GI for the grass helps getting it brighter but the color is somewhat washed out, as opposed to increasing sun intensity (which over-brightens the whole scene, eventhough the grass is perfect then).. so what im asking is if its possible to have a secondary vraysun that would only have impact on the grass object, excluding the rest of the scene..

alias_marks Posted July 17, 2008 Share Posted July 17, 2008 maybe you already tried this, but how bout brightening the grass texture? maybe upload an image of what your talking about to help us out. Link to comment Share on other sites More sharing options...
F J Posted July 17, 2008 Author Share Posted July 17, 2008 thx for the replies.. Put another direct light or regular Vray light. y another sun ? i havent tried it with another light source other than the sun but, even if i do (whether its a light or the sun), how would i make it only affect a single patch of geometry excluding all the rest? maybe you already tried this, but how bout brightening the grass texture? maybe upload an image of what your talking about to help us out. i havent tried brightening it cuz i only recently switched to PhotoShop, which i still need to find my way around (ditching my old companion Corel PhotoPaint).. unless u'r talkin' about going at it thru the Material Editor? ok, here's what i got: the 1st pic is my current lighting setup (where i just merged a vrayfur sample).. on the 2nd pic i cranked up the GI on the object properties of the grass patch, which makes it brighter but it doesnt have as much color to it as it does on the 3rd pic where i cranked up the sun's intensity (which obviously brightens more than just the intended grass patch)..

It seems a bit extreme to add all that extra GI or lighting when you can open the texture in Photoshop, choose Image>Adjustments>Brightness/Contrast or Image>Adjustments>Exposure or Image>Adjustments>Hue/Saturation or Image>Adjustments>Levels. Any of these will allow you to adjust the texture and lighten it up. Link to comment Share on other sites More sharing options...

LukeC Posted July 19, 2008 Share Posted July 19, 2008 unless your particularly after it, try turning off the vignetting in the vray camera properties. Looks like you might need to increase your vray environment a little, and like said before, having your vraysky map from your background in your environment slot will help (if you haven't already).
