cleaning up the source a bit..uploading on sunday or monday..
What I’m going to do in the next version of the lirabry is expose a way to update the world matrix of an object in the list kept by the ShadowMapRenderer.I’m still working on the best way to do this, but if you want a quick and dirty solution, you can make the list of casters public, and remember the index of each added object.If you’re not afraid of a little garbage (until the next verison comes out), simply modify the lirabry code, clear the list of shadow casters at the end of each frame, and add the casters with their correct world matrices each frame.
some amazing stuff here!
