Lots of lights // Archive: Tech Forum 1  |   Order by default Post by rjeff // Mar 28, 2008, 7:04pm rjeff Total Posts: 1260 Ok I am using an HDRI image on this and I seem to be getting alot of light sources..or at least alot of shadows..and it is this way with any HDRI I use. Why? Post by Jack Edwards // Mar 28, 2008, 7:44pm Jack Edwards Total Posts: 4062 Hi RJeff, Lightworks creates an array of lights of colors that match the HDRI image. Each light in the array casts a separate shadow. To get a smoother result you need to increase the number of lights in the array, by increasing the samples value. I found that the shadows are almost totally smooth at a setting of 100. Two other things that might help you out are to lower the intensity below 1.0 and to use materials with a color darker than white. White = max color, so it doesn't give the engine any room to make it brighter via lighting. Setting the saturation to -0.5 can also help if you are getting too much color from the HDRI image you are using. Hope that helps!

This is where I have acquired some of my HDRI maps. See how his shadows are clean and there are not 10 of them. That is what I am going for and I just can't seem to get it. Is that becuase he uses Vray and I use LW? http://www.aversis.be/hdri/balkon_sunset.htm Post by Jack Edwards // Mar 29, 2008, 10:55am Jack Edwards Total Posts: 4062 Can you post a screen cap of your HDRI settings?

You will get the same reflection but shadows vary from the kind how the render engine does it. Vray use importance sampling. LW like Jack said place more virtual light objects dependent from the sampling rate. Post by rjeff // Mar 29, 2008, 3:21pm rjeff Total Posts: 1260 OK here ya go Jack
