I can make the explosion easily, that's not the problem. The problem is the overlay will not stick to anything but a world surface. I have attempted using decals, but i found out that doesn't work for this sepcific situation. Then I tried making a func_brush with an areaportal in front of another func_brush with the brick_block and I found that the texture for the brick inexplicably hides the portal behind itself.

I will post pics after i get back from work, cause i havent the time right now.

Okey, so I have figured out how to make the portable surface with the brick_block wall overlay. But what i want to do is make it so when the player attempts to enter the portal, the wall is abruptly destroyed in front of them with clusters of concrete flying everywhere.

?! what do areaportals have to do with them? areaportals are optimization things.

The way I would do it is put a func_brush with the nodraw texture; one unit thick in front of the wall; then the side that should be portaled should be textured with nodraw_portalable; give the func_brush a nice little name.

Now make a portal detector touching the nodraw_portalable face;
OnStarttouchportal; ; kill;
Onstarttouchportal; !self; kill;
Onstarttouchportal; wall_explosion_relay; trigger;

That should do.

freudian slip, there. :p

And I think my method may have been overlooked. I am using the brick texture where there is plaster smudged all over the wall. Its an aesthetic requirement for a specific scene im doing
I cannot use it as an overlay because overlays do NOT stick to func brushes ingame, and when I used it as a texture for the actual func brush it created this glitch ingame where it sandwiched the portal between the plaster and the wall.

I will be back at my home computer in 2 hours to post pics to show you what i mean

Am I speaking a foreign language here? I said I DID that and it glitched. See that blue tinge in the image? that's the portal i just placed. This happens when only one portal is present. If two are present, the glitch subsides temporarily

EDIT: it totally didn't work
