Hey all,

I am using MAX and trying to setup a system where i pass a spotlight through a room and every where that is hit by light gets a different texture. that way i can see the places that were hit by the light at any point in time during the animation

I am using Max7 and the only solution i can think of right now is to use the particlepaint material from www.max3dstuff.com (http://www.max3dstuff.com). then i create a particle system whose origin is at the same place as the light. This in effect does what i want - however it doesnt allow for collision (ie the particles go through the objects and paint in areas that would normally be shadowed).

perhaps there is an easier way to accomplish this...

any ideas?

Add a collision event to the particles?

You want the lit areas to retain their new texture, even after the light has left them? I think this might be the only way, besides some funky compositing post effect. I was going to suggest the TouchTextureMaker (http://www.maxim-capra.com/main.php?men1=m_work&con=c_codmxs) script, but that works off geometry not lights, though you might be able to figure out a way to use it with a Light.

Cool idea.
