its really quite simple to get animated models into Blitz. If you create them in Milkshape/CharacterFX then you can just simply export as .b3d.
If you have created the animated models in Max/Character Studio you can use Valves´´ smd exporter and then use Milkshape to convert to .b3d.
If you need placeholder models have a look at Psionics´site - you can get to it from the ´links´ area.
For examples of the Max to .b3d via Milkshape have a look at:
