Troubleshooting Conversion

Having issues uploading or converting your 3D model? This page outlines the most common problems and how to fix them before trying again.

If your upload or conversion fails — or the resulting .urta doesn’t look right — don’t worry. Here are common problems, their causes, and how to fix them.

🚫 Common Upload Issues

🔹 "Unsupported File Format"

Only .glb and .gltf formats are currently supported. ❗ Solution: Convert your model to .glb using Blender or another tool.

🔹 "File Too Large"

Files over 100MB may be rejected or fail silently. ❗ Solution: Reduce polygon count, compress textures, or split into smaller assets.

🔹 "Nothing Happens After Upload"

If the page stalls after uploading: ❗ Solution:

Try a different browser (Chrome is recommended)
Ensure the model has embedded geometry and textures
Check internet speed or firewall issues

🧩 Model Issues After Conversion

🔹 "Model is Invisible"

This usually means the scale is extremely small or the model’s pivot is offset. ❗ Solution:

Apply transforms and reset pivot in Blender before re-exporting

🔹 "Textures Are Missing"

If the model loads but appears solid white or gray: ❗ Solution:

Make sure textures are embedded in the .glb file
Use glTF Binary (.glb) with packed textures (avoid separate .bin/.png)

🔹 "Upside Down / Wrong Orientation"

Some exports use different up axes by default. ❗ Solution:

In Blender, set Z-up and Y-forward before exporting
Preview model in a viewer to confirm orientation
