Hi again.
I've downloaded Tremor, set wateralpha to 0.2 and loaded a map with teleporters (e.g. qffldm5).
In the below screenshot, you'll see the earth magic rune's skin shown at the teleporter. When I'm behind a double-barrel shotgun for example, its skin is shown at the teleporter. When getting too far away, the teleporter becomes white.
Looks funny, isn't??
