What model formats can I convert?

GLB and glTF. Most 3D tools export GLB directly, and it carries textures inside one file, which makes the conversion reliable.

Do I need the YTYP file?

Yes, for a spawnable world prop. The YTYP archetype is what maps the object name to the model. The converter generates it for you.

Why does my prop look huge or tiny in game?

The source model was exported at a different unit scale. Set the export scale in the converter; the 3D preview shows the size against a reference before you export.

Do the generated LODs matter?

Yes. Without lower detail levels the game renders the full mesh at any distance, which costs performance on busy servers. Generating them takes one checkbox.

Convert a GLB model into a GTA 5 prop

Updated 2026-07-23

GTA 5 stores world objects as YDR drawables, so a model from Blender or a marketplace has to be converted before the game can stream it. The GLB to YDR converter does the conversion online and also generates the two companion files a prop needs: a YTYP archetype and a YTD texture dictionary.

Prepare the model

Export your model as .glb (or .gltf) with textures embedded. A few things save trouble later:

Keep the polygon count sensible for a game prop; huge sculpts will convert but perform badly.
Apply your transforms so the model is the size you actually want; you can still scale during conversion.
Name the model file the way you want to spawn it: the file name becomes the prop name.

Convert it

1Drop the .glb into the GLB to YDR converter.
2Check the 3D preview to confirm geometry and textures look right.
3Set the export scale and pick which LOD levels to generate; LODs keep the prop cheap at a distance.
4Export. You get the .ydr plus a matching .ytyp and .ytd.

The preview runs in your browser and is free. You sign in with Discord to use the tool, and the export itself uses tokens.

Stream it on your server

1Make a resource folder with a stream/ subfolder and drop the .ydr, .ytd, and .ytyp inside.
2In fxmanifest.lua add a data_file entry of type DLC_ITYP_REQUEST pointing at the .ytyp.
3ensure the resource in server.cfg and restart.
4Spawn it by object name with your admin menu or CreateObject in a script.

The YTYP is what registers the prop archetype with the game; without it the object name resolves to nothing. If you already have a .ydr and only need the archetype, the YTYP generator builds one from the drawable, bounds included.

Verify before you upload

Drop the exported .ydr into the YDR preview to double check the result: geometry, textures, and LOD levels are all visible there, and it runs entirely in your browser. Catching a flipped texture or wrong scale here beats restarting a server to find out.
