I want to make my first custom avatar, but I don’t know who I should look to for a tutorial.
You looking to create from scratch or use parts from existing models?
There are many tutorials on YouTube but the best thing you can do is follow a basic tutorial for blender if you want to make models from scratch -
Other alternatives are Vroid tho i would not recommend that.
Tafi avatars is another way to create models tho this is from parts but you can make some very unique creations with them. You can find Tafi avatars online.
Have fun and dont give up
