I've got a scene with a bright, textured sphere for the sky with a parallel light source inside it illuminating the other objects. Although I've given the sphere the maximum brightness value, 255, there is a visible diagonal line across it with a brighter area on one side. All I can think of is that the light source (which is at an angle) is adding a small amount of illumination to the sphere (one side has RGB 191,223,254 and the other is RGB 192,224,255) on the 'positive' side of its plane. But if the object is fully bright, this shouldn't be possible! My guess is that the "fully bright" value should be 256, but I haven't been able to find a way to set the object to this (the slider only takes it up to 255, and if I enter anything larger in the numeric box, it resets it to 255 again). This is with Imagine DOS version 4.0, BTW. Any suggestions? The only easy alternative I've come up with is to load up each frame in turn into an art package and flood fill all the brighter bits with the slightly darker shade. --------------------------------- Date: Fri, 2 Jan 1998 06:41:42 -0500 From: gregory denby That would be my guess too. Try duplicating the light, and rotating it 180 on its z axis, so that you have a parallel beam facing the opposite direction too. As to why this would happen, my guess is that the texturing on the sphere slightly interferes with the max brightness just a wee tiny bit. Just a guess tho.
