ok so i 3D modelled a sword using autodesk inventor so i could make a mod for blade and sorcery. i have it in unity and im fairly sure i have everything worked out. but i have no clue where i would even begin to texture this thing, because i 3D modelled it myself im assuming i would also need to make my own textures? im not entirely sure how they work, Modelling i can handle, texturing is like a completely different language to me. Any tips? All help greatly appreciated.
