$nocull

Template:Shaderparam It disables backface culling, resulting in triangles showing from both sides. It is used to allow for infinitely thin dual sided objects without duplicating the triangles with reversed vertex order. Lighting will still only be calculated from the "front" side of the face, and be copied to the reverse side, potentially creating an effect where light bleeds through to the other side like a thin sheet hung up in direct sunlight, so use with caution.

Note:Has no effect on world brushes (so tie each one to func_detail). Works on displacements.

Confirm:Seems to only work on func_detail.

Bug:Cannot be used with $translucent on models. Use $alphatest instead.

Confirm:Does it work with $alpha?
