1. Insufficient Tessellation Quality on Native Revit Pipe Catalog Elements

   • When converting Revit models containing pipe catalog elements (pipes, elbows, couplings, tees, etc.), curved surfaces may appear faceted rather than smooth due to insufficient tessellation resolution.

   • This results in visual artifacts and faceted shading on cylindrical and curved pipe components in the converted USD output.

   Workaround: Scene Optimizer Utilities

   To improve the visual quality of affected pipe elements:

   1. Disable the “instanceable” flag on meshes that require the workaround.

   2. Run Scene Optimizer Mesh Cleanup with all settings enabled.

   3. Run Scene Optimizer Generate Normals with default settings.

   Note: The instanceable flag must be disabled before applying Scene Optimizer operations for the changes to take effect.

   Note: Scene Optimizer operations can also be executed programmatically via Python as a post-processing step. For more information, see Scene Optimizer Python Usage.
