How do I make a floating overlay?

I've tried applying an overlay to a brush with nodraw and one with noclip applied to it, but the overlay does not show up in game. Anyone have a clue as to how I can get a decal\overlay to appear as if it's floating (I'm trying to make it look like I have a decal applied to a static model)?

Thanks for the help..

Oh, and your board doesn't let users who are running opera post, when I hit submit it deletes my message and tells me I have nothing in my body.

Well, sorry about that, but Opera does suck ass. :razz: And try applying it to one covered with toolsinvisible?

you could also ally the decal texture to a brush and place no draw on all other sides.

You know what I suggest? Old HL1 style blue 255 invis texture... That should work fine. It is an actual brush, whereas the others are specialist tools that work in different ways. This method should work fine.

Thanks a bunch for the replies, guys. I'll probably do as DrGlass suggested and just put the decal onto a brush (and no draw the other sides). If there's any reason I shouldn't do that (please speak up) I'll go with the blue method. I take it HL 2 still renders pure blue as transparent? I know it no longer does this for sprays (so I wanted to ask before I went to the "trouble" of making a pure blue texture).

Quick Edit: The invisible texture also works, so I won't be bothering with the blue texture. Would still be interested in knowning if HL 2 renders pure blue as transparent, though.

Thanks a bunch.

I think it uses other colors too ... and it does it automatically, not through a func_ brush anymore. There are grates and such that are transparent but are black in the middle and there's vines with pink that disappear ... so, not sure. I think they made it in the texture properties (since you apply sounds and texture to textures now, I imagine you can add transparency maps too).

Decals use alpha maps to decide transperancy. I said apply it to
a brush, the solid world object kind not the func_brush kind. All
though if you have a decal suspended in air it might be wise to make it
a func_illusionary so the play dosn't bump into.
