How To Realistically Texture Characters for BGE

So, first time posting in this form. Not sure if it’s suitable, or even the proper form of that matter. Either way, thanks for viewing this.

After watching some gameplay videos, I found out that my player graphics are way outdated. Not even 2015 game quality.

So I came here to ask: How do I realistically texture a character for BGE?

I included BGE, indicating that it isn’t a high-poly model for rendering.

hi to lo res baking. pbr-esque materials.

Alright then, thanks!

So what about detail? My detail seems to be inconsistent and inadequate.
