Apologies if this is answered before, my searches have come up empty.
How do I adjust the height on an NPC that I am making without creating a new Race for him?

It must be possible e.g. Hil the Tall is a Nord but is a lot bigger than a normal one. I can't find anything in the Construction Set that changes him, although I am so inexperienced with the CS I am obviously missing something.

Hi try this

Player.SetScale 2.0

That will change your height, hope that's what your after, and i think 2.0 is the max setting.

You have to place the NPC in the game world somewhere. Once you do that, double click on them in the Render Window and set their scale there. That is how Hil the Tall was given the extra height.

I'm making a companion mod, it's the companion whose height I want to change.

edit: thanks Vyper.

You're welcome.
