I made a sword in Blender that I'm really happy with, but I only found out afterwards that fbx files are incapable of having textures, or something. Bottom line is, in Blender the sword looks awesome, but as soon as I export it, it is just grey and featureless. Could someone please help me figure out how to attach textures (and materials)? I've tried looking online but I only kept finding things about the unity engine.

Thank you.
