When do I add hair to my model? I have sculpted a humanoid Rat and have retopologized it. As many of the youtube tutorials say, I am supposed to proceed to UV unwrapping. I want to add hair to my character (fur to be specific) and it will be an animated character (I will rig and get it animated from Mixamo).
Now what should I do? Should I add hair particle system before uv unwrapping to the retopoed mesh or after it?
You can do UV unwrapping and hair particles independently of each other.
UV unwrapping creates UV maps. You can find them in the Object Data Properties.
Hair particles create particle settings and adds a hair modifier to the object.
As long as you haven't started to paint textures or edit/comb the hair you can delete uv maps and particle settings and re-create them.
