Model GLB Export

Overview

Exports an assembled Model as a self-contained .glb, the binary glTF format with embedded textures. It is the 3D exit of the Model lane and can be imported directly into Unity, Godot, Blender, and similar tools. It also bakes rigid-body animation.

Usage tips

• Follow the standard export-node workflow: edit with Save Mode = Disabled, confirm the destination, then switch to CreateIfMissing or Overwrite.
• The initial destination is exports/models for a saved project, or the configured "3D model export" folder for an unsaved one.
• Bake rigid-body animation: setting Animation Frames to 2 or more bakes upstream motion, such as waveform-driven model_transform, into glTF animation as rigid-body TRS for each stable PartId. Export the same motion as pixel art through model_render → animation_render to produce both GLB and a sprite sheet from one graph. workflows/model_chest_animation_c7.ppl is a complete example.
• Use .pxmodel through model_asset_save, rather than GLB, for intermediate editable saving.

Common pitfalls

• The animation contains only one frame: Animation Frames is still 1. Set it to the total frame count.
• The engine cannot identify part names: each part's name is unset. Give parts stable names in their generator nodes before exporting.
• Textures are rough or bleed: the GLB receives textures bundled by pbr_material. Base resolution on the recommendation from model_texture_layout, then reserve a gutter with texture_layout_dilate.
