Nah.

Those format can't be used with each other - they are as different as chalk and cheese! I'll explain why.

MD3 originated in the Quake3 engine and is a format to store models of players and other non-static objects in the game. Animations are vertex-based and are stored within the very same file the model is.

SMD, on the contrary, is a model used by the Source engine (even nowadays). It's more common in it's compiled form - an MDL file. This format uses skeletal animation and every animation is stored in a separate file, outside the model file. Usually they're packed together in a .MDL file.

That is why you must decide what type of animation you want to use with your game. I'd suggest using the MD3 format, as it's easier for beginners.
