How to UV Map .obj Meshes?

How would I uv map .obj meshes without using blender or anything relating to blender?

I can’t get blender but there sure has to be an solution to this. I’m doing this for the dismemberment in my blood system for a .obj mesh part I made of an character bevel mesh.

How can I achieve this?

It would be cool if Roblox implemented a system which supported this. Have you seen any demonstrations of this?

Anything relating to blender?

well i mean there’s many other programs that isn’t blender if that’s what you meant
yeah that’s really not an option to “UV Mapping in Roblox Studio” from what i’ve heard but there’s programs related to texturing which auto-UV unwrap, though the most well known one, Substance Painter by Adobe is paid.

okay but aside from that
there’s 2 options that seems the accessible: get somebody else to do the UV unwrapping for you
OR
pray to god the Roblox engine cooperates with you and has a UV unwrap out of the box that satisfies your need?
