Basically I am creating air shaft vents with grates that cast criss-crossed shadows on the opposite walls. I'm using a grate texture with a brush behind it that has tools/blocklight texture to create the effect, but it requires multiple func_details to create the effect.

Is their a better way to do this?

Haven't used it myself, but I think this ent should help you create the effect you are looking for:

I was originally using the projectedtexture, but I read that portal2 only lets you have one, and removes additional projected textures if you have them. I'm also planning on having like 10 or so in the map. If someone knows if you can have more projectedtextures and its better than the method I'm doing that would be great.

Have a nice day,

EDIT: dammit ABP beat me to it.

If you're using another in your level you need to make sure to fire a TurnOn at it in order to enable it after you've left the main Entry Elevator (I think the elevator env_projectedtextures automatically turn themselves off when you leave the area).
