func_illusionary

func_illusionary
Type	brush
Status	supported

Essentially an entirely non-solid func_wall. If it has toggleable textures, they will toggle when the entity is triggered.

Keyvalues

Contents : skin

It's used to change the 'contents' of this brush (e.g. volumetric light makes it behave as water when entities going though it). You don't really need to use this.

Flags

2 : Use angles

If set, the func_illusionary will use its angles.

Notes

Even if non-solid, the compiler will still generate clipnodes for this entity. Set "ZHLT Disable Clipping" to 'Always non-solid' to prevent that (zhlt_noclip key with value of 1).
Alternatively, use SKIP texture instead of NULL on faces that have the texture on the entity.
