The glTF hierarchy importer can import a glTF scene as a network of nodes or as flattened geometry. See the following link for further information about the glTF format.
See the following link for an overview of importing and exporting GLTF files to and from Houdini.
The glTF file to. The loading method depends on the extension of the file loaded.
Files with a .glb extension be treated as binary GLB files.
Files with a .gltf extension will be loaded as normal JSON data.
Asset Extraction Folder
Textures packed into a glTF binary buffer or represented as base64 data must be unpacked before usage.
This field specifies the location textures are to be unpacked on disk.
Select the scene to import from the glTF object.
In the absence of a scene name, the label will be based off the scene index.
Build the scene from the input parameters. If the scene was loaded previously, this will reload the scene hierarchy and geometry.
Enable this option to lock any geometry nodes created during scene building.
Flatten all nodes in the scene down to a single node containing all the geometry.
Promote Point Attributes To Vertex
Promote all point attributes (excluding P) to vertex attributes.
Points Merge Distance
When Promote Point Attributes To Vertex is enabled, points within this distance to each other will be merged.
Enable this option to import geometry objects. When disabled, glTF meshes will be loaded as empty Geometry nodes.
Import Custom Attributes
Enable this option to import any custom attributes from glTF primitives.
Custom attributes in glTF are prefixed with an underscore _ which will be stripped during import.
Enable this option to import glTF materials as Principled Shader materials. This also creates material assignments.
If this option is disabled, materials and material assignments will not be created.
Import nodes which do not create or transform any geometry. Disable this to remove unused nodes when the additional hierarchical data is unneeded.
Import Unused Materials
Import all materials available, even if they are not assigned or used by the imported scene.
