"That one's on the list, but fine. Entry accepted."

Turbulence textures might be thoroughly abandoned by some.
However, map compiler options might make a difference.
Turbulent blocks might have turbulence HERE with map compiler option "Build BSP Map" or similar selected, and "Build Simple Map" + "Create Meshes" or similar NOT selected.
(HERE, turbulent blocks might be invisible with "Build Simple Map" + "Create Meshes" or similar selected.)

Hopefully, that is relevant, or at a bare minimum..."sparky".

Good luck with the contest.
