I am trying to export some playermodels i made, but on both of them, the skeleton in the Unit_template_beta is taller than the model:
Do I need a special Skeleton? do i need to scale the Skeleton? hlp a n0oB!

You could fix that problem by fixing the proportions on your model. As it is, the thighs are "taller" than the entire torso and head. That is absurd.

The real answer to your question is that it's simply easiest to resize your model to fit the skeleton in any case, but as I said, just fix the proportions.
