Hey, I'm trying to make a floor on my map transparent, I've done up the alpha maps and made sure everything under the grate had a "!" for render only (for the sealed world rule).

I just realized I have no clue how to make the shader work, and there aren't any tutorials on how to do this with the shader_environment tag, only decals.

This is the effect I'm going for:

Can anyone point me in the right direction?

first in the materials make the grate lets say the grates name is metal_grate add a % to the end of it. make it a shader enviorment if it has a alpha. then take the ! away from the material under it.. make the bottom part and connect to the grate and export

That would exclude the grate from the collision geometry though right? I don't want players falling through the floor... And the "%" is renderable from both sides, but that doesn't help with the alpha.

no % will make it export right then under it model the bsp... trust me ive tried all kinds of mapping possible... the reason why i say model the under piece so u dont look down at the sky...

If you want the alpha don't make it a shader_environment. Use shader_tansparent_chiago or glass. I think any of the shader_transparents work.
