Supported File Types
Gestaltor supports saving both glTF and glb files. Additionally a wide range of 3D file types can be opened with Gestaltor or imported as a new scene to the currently open glTF file.
| File Type | Description | Open | Save |
|---|---|---|---|
.gltf | glTF file | ✔️ | ✔️ |
.glb | Binary glTF file | ✔️ | ✔️ |
.usdz | USDZ file for Apple AR Quick Look | ❌ | ✔️ |
.blend | Blender file | ✔️ | ❌ |
.3ds | 3D Studio Max file | ✔️ | ❌ |
.dxf | AutoCAD file | ✔️ | ❌ |
.fbx | Autodesk file | ✔️ | ❌ |
.obj | Wavefront file | ✔️ | ❌ |
.ply | Polygon file | ✔️ | ❌ |
.stl | Stereolithography file | ✔️ | ❌ |
.x3d | X3D file | ✔️ | ❌ |
Importing files from other formats is currently a lot slower than just opening them, therefore it is generally advised to open other file types directly from the File -> Open menu.
Keep in mind, that conversion of 3D data is usually lossy and can lead to unexpected results. If the import is not working, try to use a native exporter to glTF from the original software.
The binary data in glTF files (buffer and images) can be stored in different ways:
| Storage Type | Description |
|---|---|
| Embedded | The binary data is stored as base64 encoded string in the JSON file. This leads to larger file sizes but is easier to handle in some cases. |
External .bin | The binary data is stored in a separate file. This leads to smaller file sizes but requires additional files to be handled. |
| Binary GLB | The binary data is stored in a single binary file. This is the most compact way to store the data and generally the recommended way. |
Embedded files are not always handled correctly by other viewers and should be avoided due to their overhead in file size and performance.
Useful Operations
Cleanup
The cleanup operation allows you to remove unused resources from the glTF file. This can be useful to reduce the file size of the glTF file. The cleanup operation can be accessed via the menu Automation -> Cleanup All.
Export USDZ
Convert a glTF file to the USDZ that is compatible with Apple's AR Quick Look. The operation can be accessed via the menu File -> Export USDZ.
Rearrange Nodes
You can easily rearrange the nodes in the scene graph by dragging and dropping them in the hierarchy view.
This also includes moving attached properties like meshes or materials from one node to another, e.g. when cleaning up a scene with deep nesting.
Material Editing
The material inspector allows you to add glTF specific PBR material extensions to the material that might not have been supported by the exporter but should be present in the final model.
There are functions to create thickness maps for the KHR_materials_volume extension, as well as to add clearcoat, transmission, and sheen to the material.
