at work i've been trying to find a solution for shadows popping/ flickering around as objects turn invisible. time is an issue when rendering the final aniamtion and u have to remeber it has to look like its got GI.
heres r some things i've tried.
1. light dome with 13 lights with shadow map , which is when i remembered that shadowmaps don't work with shadow maps. (i was gona try something crazy if no other solution ,like having a seperate dome for each group of objects that will fade, excluding the other objects and fading the shadows away, .... i know crazy to set up... well kinda...)
2. a light dome , 13 lights but with raytraced / Adv raytrace shadows / area shadows. better results but time was alot longer because had to mess with shadow settings to get GI look which increased the render time alot.
3. Skylight+lightracer (for shadow pass) and then a 13 light setup with no shadows for the Diffuse+spec+reflec pass. i really liked the look once Comp together but again the flickering and popping.
4. tried Mental ray too, similar things but i never really liked ray so left it.
pretty much tried everything, i think my only option left is to render the objects that will fade as a seperate passes and then lots of comping in combustion
anyone help?
thanks
