My models seem to keep sinking into the floor and walls, despite my having tried the following:

• Manually setting min_x, max_x, etc. to large values (~256).
  
• Compiling a level with large -narrow and -fat flags (~256,256,256).
  
• Manually setting the entity to .fat=1 and .narrow=0.
  

I'm using ent_move(), and at the moment, can't switch over to c_move(). Can anyone offer any pointers?

Thanks,
