i have programmed a function called supertrace() which offers this functionality:
http://www.coniserver.net/ubbthreads/sho...true#Post745256supertrace.zip ~ 500kb
it's a free separate plugin. to try out the example script extract the zip file to the directory with the mesh plugin demo.
with this function entities will be able to react to shadows below them. (another thing which wouldn't be possible if you just baked everything into one texture.)
it could also be helpful for other things.
it was a bit tricky to implement and it is experimental. i don't know if it is usable for real projects.
