Hi there, Some of you probably know I'm making my first Hammer underground map, thanks for all your help so far, the only trouble I have now is getting the underground style buttons instances to work. I put a cube button in (the one that has a grating around it with a square hole at the top for the cube to go though), but when I run the map and try to put a cube on the button, guess what? The cube wont go down the hole, it just floats there, as if some kind of invisible wall is in the way!

I had a look inside the instance and noticed there's a func_clip_vphysics, I have no idea how to use that, and looking it up provided absolutely NO help whatsoever, but I did notice it has a filter name "@isball". That doesn't even seem to make any sense tho, if anything shouldn't that be "iscube" or something like that? It won't even let balls though either.

How do I make it let the cube though? I have no idea what I'm doing, I even tried naming the cube "isball" and "@isball" to see if that would work, it didn't.

You want to have the p2editor_old/global_ents instance in your map, it has all the filters inside it. The isball filter blocks balls from going through the hole.

This is more of a self preference, but Valve used prop_floor_button_cube with a base fitting the environment.

The cube buttons and other modern elements were installed by GLaDOS, and weren't originally there.
