I want to turn .obj to .mesh

[cozfl (Luke)]

How would I turn an .obj file into a .mesh

(If this is the wrong place then please correct me)

Why do you want to do that?
obj is more compatible than mesh.

Art Design Support is for working with modelling, this doesn’t belong in Game Design Support. I’ve recategorised the thread accordingly.

There are .mesh files - see rbxasset://content/head.mesh and various others.

Thanks, I am not used to devforum.

Extremely late reply but for anyone wanting to do this in the future here’s a solution. The .mesh files Roblox uses (such as head.mesh) are not normal .mesh files, they only work on Roblox’s engine.

Roblox FileMesh Format Specification

( Latest Revision: 3/30/2025 ) When a mesh is uploaded to Roblox, it is converted into an in-house format called FileMesh, that the game engine can read and efficiently work with. Roblox’s FileMesh format isn’t a format you can normally export to or import into Roblox Studio, but you can download meshes by their assetId using the assetdelivery API. This resource aims to be an unofficial spec for interpreting this format, so you might be able to write code externally that can read FileMesh file…

If you want to convert it you have to upload the mesh to Roblox like normal and copy the assetid. Then enter the link in your browser as shown below but add the copied assetid at the end:

https://assetdelivery.roblox.com/v1/asset/?ID=(enter your assetid here)

A download should start and rename the file to whatever you want. But note it must have the same name as any other mesh in the Roblox content folder you want to replace, such as a body part in the avatar folder.

I’m trying to use meshes in a old version of roblox studio for fun, but it seems like the meshes you get aren’t .mesh are just a random letters.

Okay never mind I used a plugin that just let me download the mesh file

idk how it worked but it did so uh yay

Do you mean the file you get back has a name like “jDIUHgasdvUASDys” or something? That’s normal, I think it’s the hash. It does the same for image files. Just rename it to have the .mesh ending.
