env_beam not striking func_brush

[Penguin]

as the title says, env_beam doesn't seem to be generating an output when it strikes a func_brush. based on the vdc wiki, i'm not sure it can.

so my question is two parts:

1) is there a way to get it to hit the func_brush?
2) is there another way to detect hitting a func_brush like that?

as far as I know for beams you need a starting node and a finish node - have the path go through the brush then put a decal or overlay or dynamic brush with an overlay texture on 1 face (the face that is getting hit) and no draw on all the others - then triggger it to appear when the beam hits it

not what i was asking, but thanks. i need the OnTouchedByEntity output to fire on the beam when the beam passes through the func_brush, which isn't happening. from this i conclude that the beam is not interacting with the brush at all. i don't care about the visuals at all, i just need a way to tell if a given direction does or doesn't have a func_brush in front of it.
