can someone rig these new terminators model?

they are high definition models, they are free to download, just add autors to credits, can someone rig them?

I’m no modelling expert, but I think they might be too high-poly for source.

i now, but, someone could reduce model and texture

The Source Engine can comfortably render and display a 4096x4096 texture.
(But you’d probably need an awesome top-end graphic card to display it at max level)
