Playermodel Rigging in Blender

How do you rig a model with the ValveBiped.Skeleton?

Do I just use Automatic Weights or does there have to be some fancy-shmancy Weight Painting? And is there anything else I should take note of when rigging?

Just rig it to the ValveBiped like you’d rig any other skeleton. Look up some tutorials for that on Youtube if you don’t know how.

as a Blender aficionado my guess is auto weigh and then fix it up manually as you normally would
