Virt-A-Mate. from Sex to WG 3D game

I saw you’re stuff and was immediately interested in trying my hand at it. I’m getting started with basic tutorials & stuff, but I just wanted to ask.

The stuff you’re doing, with the gaining mid scene & model manipulation at all. What version minimum is required to do all of that, and you’re not using any external plugin (If those even exist, as I know they do for other things like Blender) are you?

I’m extremely interested in picking this up. Thank You.
