How to make a 3D model for mods

Modding is where a good idea dies on the asset. You know exactly what the object should look like, and building it in Blender is a weekend you do not have.

Meshcraft turns one reference photo into a 3D model you can import, in two to three minutes depending on which engine you use.

What you get from one photo

Every generation produces the same three files:

  • The original model, at full detail. This is the highest-fidelity version and it is the one to open in Blender if you want to edit before importing.
  • A game-ready GLB, scaled to 4 studs on its longest axis and textured in a format game engines read. This is the file to import into Roblox Studio.
  • A print-ready STL on paid plans, scaled to 100 mm on its longest axis, if you want the object on your desk as well as in the game.

Why the game-ready file exists

A raw AI-generated mesh arrives as thousands of separate pieces, and dropped straight into an engine it renders full of holes. That is a structure problem, not a quality problem. The game-ready file is the same model after the step that collapses it into one solid, so it imports and looks like the thing you uploaded.

The honest limits

  • Roblox is the import path we have verified. The game-ready GLB is a standard format that other engines read, but Roblox is the one Meshcraft is scaled and tested for.
  • One photo makes one object. Meshcraft does not build rigged characters, animations or multi-part assemblies.
  • Uploading a photo costs 1 credit. The Premium engine costs 50 and produces a noticeably better mesh. Typing a text prompt instead of uploading adds 1 to 9 credits for the image step, depending on which image model you pick. Creator includes 150 credits a month.

Start with the thing on your desk

Point a camera at it, upload the photo, and see what comes back. New accounts get a 7-day trial; a card is required and is charged only if you do not cancel before it ends.
