I'm building a room that is dramatically reshaped with panels that have func_brushes attached to them. Mechanically it works fine but due to the way it reshapes the lighting should change rather drastically, however with func_brush's static shadow generation this isn't happening. I'm trying to determine what I should be using to get shadows to change as these panels move but still using a brush or entity that allows me to use the textures of the room.

Thanks for the help.

I think what you're looking for is an env_projected_texture

You mean env_projectedtexture

Thanks, this isn't quite what I'm looking for. I would prefer to not have spotlight-like lighting and be able to have more than one light source. I'm looking to have these lights change the shadow on my func_brush or its substitute as the brushes move. Is this simply not a possibility?

Take a look at light_dynamic. It's expensive to render, but may be able to do what you want.

isnt there just a "YES" you have to set to one of the func_brush's shadow related parameters?

Or a NO if its filed as "disable shadow related thingy?"

I believe I tried every shadow and render-related setting available.

Disable Receiving Shadows: No
Disable shadows: No
Projected Texture Cache: I thought this was the problem, but I've tried all the settings with no luck.
Disable flashlight: No
Solid BSP: Tried toggling this, but I believe it's just player-physics related.
Shadows: Yes

I'd prefer the light not have hard edges and a defined source (more of a soft box than spotlight) which I can't see how to do with light_dynamic.

As far as I know, regular shadows get baked into surfaces during compile and remain static after that, with the only option for dynamic shadows being env_projectedtexture. Id try experimenting with that, maybe you can make it look less like a spotlight and more regular-light-ish. Im not sure about dynamic lights, but I dont think they cast shadows.
