Godot Stage currently supports VRM models only.

Error message

Godot Stage currently supports VRM models only.

What it means

Thrown by assertGodotSceneInputSupportedDisplayModel when the resolved DisplayModel's format is not DisplayModelFormat.VRM. The Godot stage scene input path (G1.1 baseline) only loads VRM models; Live2D, MMD/PMX, or unknown formats are rejected before model bytes are read and sent to Electron main.

Solutions

1. Switch the active display model to a VRM (.vrm) model before enabling the Godot stage.
2. If a VRM was intended, re-import it so the store classifies format as DisplayModelFormat.VRM.
3. Use the Three.js/pixi stage renderer for Live2D/MMD models.
4. Gate the Godot-stage UI so non-VRM models cannot be selected for it.

Example fix

// before
assertGodotSceneInputSupportedDisplayModel(model)

// after
if (!isGodotSceneInputSupportedDisplayModel(model)) {
  // disable Godot stage input, surface a user-facing message
  return
}

import { DisplayModelFormat } from '@proj-airi/stage-ui/stores/display-models'
function canUseGodotSceneInput(model: DisplayModel): boolean {
  return model.format === DisplayModelFormat.VRM
}

import { DisplayModelFormat } from '@proj-airi/stage-ui/stores/display-models'
function isVrmDisplayModel(model: DisplayModel): boolean {
  return model.format === DisplayModelFormat.VRM
}

try {
  assertGodotSceneInputSupportedDisplayModel(model)
} catch (e) {
  // disable Godot stage input, show 'VRM only' message, keep current renderer
}

When it happens

Trigger: User selected a Live2D or MMD display model and switched to the Godot stage renderer; a display model resolved to a non-VRM format; the format enum on the stored model is missing or unknown.

Common situations: Mixing renderer backends — Godot stage selected while a Live2D model is active; imported a .pmx/.pmd that the display-model store classified as MMD; model record missing format field defaulting to a non-VRM value.
