Some Boom scrollers doesn't seem to work at full power. The Boomref file lists: > 245 -- Scroll Tagged Ceiling w.r.t. 1st Side's Sector > 246 -- Scroll Tagged Floor w.r.t. 1st Side's Sector > 247 -- Push Objects on Tagged Floor wrt 1st Side's Sector > 248 -- Push Objects & Tagged Floor wrt 1st Side's Sector > 249 -- Scroll Tagged Wall w.r.t 1st Side's Sector > The amount moved is the height change times the trigger > length, divided by 32. But in Vavoom/Doom2 if a floor with a 64-length scroll vector moves 32 map units up or down the tagged sector's flat or wall moves only around 40 units. Also the Boom's wind and mud effects could use more oomph. A test wad here:

As better explanation: When in the original Boom the scrolls move a texture or a flat 64 units in Vavoom they move only around 38-40 units.

Fixed.
