For those who don't know, "Heat Effect" and "Inside Plax" (Parallax?) are two tile types which can be found in the 1.00 JCS but don't actually seem to do anything. Found one!


Tile 6,25. It gets used like that in both Race1 and Race2, but not Tube1, Tube2, Tube3, Battle2 or Capture1. I don't know why. It's not like it even tiles...



EDIT: It's also used:
Tile 6,9 in Capture4, sharect2 and Share1
Tile 7,9 in Labrat1
