Light halo not go through objects???

Hi there.

I’m trying to get a spotlight set to halo to shine through a slightly open door way, however, the halo part of the light shines right through the objects, such as the door. Why does it do this, and how do I get the effect I want???

When I render I get this kind of look, even though the light is behind the wall and door?

ok, my internet is working really nice right now… here it goes… >>>halo.blend<<< i hope this help you!!!

Set the halo step value in the spotlight panel to something higher then 0. Usually 1.

Thanks so much Daniel and Cyborg Dragon! That worked nicely!

Now I’ll be able to cary on with my movie.

Thanks again.
