Hey guys, I’m working on populating a scene with billboard people, if the sun isnt coming from a perpendicular position to the billboard people, the shadow created is only a thin slice, is there any way to get the actual shadow as opposed to this thin shadow?
Re: shadows w/ billboard people
A trick that may not create an accurate shadow (only a 3d person would), but may allow you to come up with a better result is to actually have the billboard that is perpendicular to the camera, and one that is perpendicular to that (ie parallel w. the camera). What this will essentially do is create a billboard that is for the camera, and a second one that might cast better shadows than just the one. Its a trick that is used in plants a lot, but it can be useful for people too.

… if we will get an “invisible for camera” option, than invisible billboard objects could be used to improve the shadow. One reason more for that feature.

…completely agreed (you could even orient them normal to a sun vector), but thats not a solution for today ;D
