directional sprites and floors and ceilings

I know how to edit floor and ceiling, but how do you make it show in game?
and how would i get directional sprites to be used as sandbags and windows? (like in totenkopf)


thanks

To get the floors/ceilings/weather effects/shading to show up in game you first have to uncomment those corresponding lines in VERSION.H of the sdl wolf3d files.

Then I use ChaosEdit, then enable 3rd Plane and Feature Flags...

ok, so what do i take out?
