Invisible Doorways

[cruizer]

I've been looking, and have come up empty handed, on how to make invisible doorways, i.e. a wall the looks solid but one spot you can walk through.

Anyone know where I can find that information at?

func_illusionary is what you want to use.

Just make one in your doorway and make sure the textures line up.

illusionary is probably a closer spelling, but still probably wrong, but this is definatly the thing to use. Use the clipping tool to clip out the section of wall you want to be the door way, select it then hit ctrl+t to tie it to an enity then make it a func_illusionary

Just a tiny suggestion: Use func_brush with "Solidity" set to "Never Solid" instead of func_illusionary. Func_illusionary is technically a legacy entity.

I've heard argument that f_illusionary uses less resources than f_brush since it's simpler and is thus better to use if you never want to do anything to it... never found proof of such though.

It's certainly possible. Func_brush has a large number of fields. If you adjust the "Input Filter" to disable all I/O, I wager the performance loss is negligible.
