Can someone tell me what models are supported with lite-c?

so far I know .mdl files are supported but does it allow any other stuff?

AFAIK only mdl, but you can export to mdl from max, maya, blenter and others

You can Import Models from .fbx, .3ds, MicrosoftX, Milkshake.
File --> Import

Thanks for the answers, so if I can find a model that was made in 3dsmax I can import to .mdl through milkshake then use in the game? sorry I'm new at this lol.

no need for milkshape,

it's either

ms->med
or
3dsmax->med

this is how you import .max models:
