Troubleshooting

Textures are white

Check the names of images not found in the Model tab's info panel → Textures. Upload the whole model folder including textures; a single file does not bring its images along.

Motion does not move

• Make sure it is an MMD model (PMX or PMD). VMD cannot be applied to glTF.
• In the Motion tab, check that the motion is not left on Rest pose.
• Parts whose expression sliders you moved are pinned over the motion. Try Unpin all.

A mod does not apply

• Check that its switch is on in the Mods panel.
• If mod.json sits in the same folder as the model, the app says it did not open it as a model. Move it to another folder.
• If material values are not visible, switch Shading to Anime toon or Face SDF shadow.
• Yellow warnings under the mod row name materials, morphs, bones or textures the model lacks.

An XXMI outfit is off

• Adjust position and size with Fit outfit.
• If some pieces look broken, try Auto-fix overlapping meshes on or off.
• Check the 'stretched triangles' percentage and unread lines in Diagnostics.

Nothing appears on screen

• If you see "Could not start 3D rendering", you need a modern browser that supports WebGL2.
• If WebGPU misbehaves, open the page with ?renderer=webgl2 added to the address.

There is no folder connect button

It shows only in Chrome and Edge, which support the File System Access API. In Firefox and Safari, use drag and drop.
