How can you add fingerposing to custom models?

So lately, I’ve been working on a model I’ve been working on and deciding to import it on Garry’s mod, the model itself works just fine, but the problem I had with it is the fact that the fingers are not pose-able, I tried searching this up around google and I seem to get no solid answer to make this, if someone here could help me out, I would be thankful.

I think you’re better off going here for a question like that.
Good luck :smile:
