Validate Scene Layer (Data Management)—ArcGIS Pro

Summary

Evaluates a scene layer package file (*.slpk) to determine its conformity to I3S specification.

This tool will validate a scene layer package against the I3S specification to identify issues that may cause problems when viewing the scene layer in an ArcGIS client application. Consider running this tool before publishing a scene layer package generated outside of the ArcGIS platform.
The tool will assess the following:
- Presence of expected values for all required and recommended JSON objects.
- Presence of declared textures for buildings, 3D objects, and integrated meshes.
- Presence of declared attributes and associated statistics for points, building, 3D objects, and point clouds.
- Presence of declared vertex attributes such as position, color, UV, and normals.
- Presence of root nodes and declared child nodes in the node tree.
The output report defaults to a readable JSON file but can also be generated as a text or XML file. The report lists warnings for issues that do not conform to the I3S specifications but may not cause a problem in displaying the data, and errors for issues that will cause problems in rendering the scene layer package.
