Since I'm a bit lost when it comes to singleplayer mapping, I have decided to leave my "Carceri" map (Pic1, Pic2) alone for an undetermined period of time. I might eventually transform it into a HL2DM map.
My next Source map will be a partial remake of Tinnos. (I know Freshed wants the new version of "Sacrifice", but it will require much more time if I want to make it teamplay). The map will have a couple of rooms from the HLDM version (which I consider some of my all time best) and I have converted most of the textures into materials. Instead of 64x64, they're 256x256 and will be fully bumpmapped in the near future.

Besides the conversion of these textures, I will apply my recently acquired skills creating Source materials to make this type of physboxes (refractive, reflective and bumpmapped) which will solve the problem of grav gun objects to throw around. (the vast majority of HL2 props are out of place in a map like this)
