Silhouette may produce slightly different results when using the PowerMesh Warp node compared to Mocha Pro. This difference is expected due to variations in implementation between Silhouette and Mocha Pro.
Differences between PowerMesh in Silhouette and Mocha Pro
Silhouette PowerMesh Warp and Mocha Pro Power Mesh use similar underlying concepts but are not identical in processing.
As a result:
Rendered output may differ slightly between Silhouette and Mocha Pro
Small variations can appear in final composites or motion tracking result
