Haha md2 go brrrr
If you really wanna use the HighPoly models, you need to do ALOT of things,
First Open up Misfit Models 3D or Maverick Models 3D, if you dont have them, download them!
Then you open up the SONIC.md2 file on MM3D and Begin the Porting.
heres the names:
SPR2_STND
SPR2_WALK
SPR2_RUN_
SPR2_ROLL
SPR2_SPIN
SPR2_SPNG
SPR2_FALL
SPR2_EDGE
SPR2_LIFE
SUPERRUN_
SUPERWALK
SUPERFLT_
SUPERSPNG
SUPERFALL
SUPERWAIT
Keep the airhurtdie things, and Super [the name of the animation that shows Super Sonic's Frames]
this is just for Sonic Only, writing it for other characters might take forever.
Being on track
Port it onto 2.2
Example: SONIC MD2/SONIC.md2 3.5.0.0
Hope it kinda helps..
Tell me if MM3D works on Mac.
