morph-ppt-3d

Use the officecli add command with --type 3dmodel, passing the .glb file path, a consistent shape name, and position, size, and rotation properties. Only the .glb format is supported; convert .fbx, .obj, or .gltf files first using Blender.

Free GLB models are available from Sketchfab (filter by downloadable and glTF format), Poly Pizza (all CC0 licensed), and the Khronos glTF-Sample-Assets repository on GitHub. Always check the license before downloading; CC0 and CC BY allow free use.

Cloning a slide copies the model as frozen XML, creating two model3d elements with the same name, which PowerPoint removes during repair. Instead, add the model fresh on each slide with the same name property so Morph transitions work.

The Hermes adaptation does not auto-install OfficeCLI; you must verify the officecli binary exists and is compatible with Termux using command -v officecli and officecli --version. If unavailable, fall back to existing docx, xlsx, powerpoint, or pdf skills.

Only .glb files are supported, models cannot be cloned between slides, and camera depth or meterPerModelUnit cannot be set manually. Adjacent slides also need a model area ratio of at least 1.5x or at most 0.67x for visual contrast.
