Hey @justin-bobbitt , glad you find the addon useful!
Once the decal is projected you can tweak the strength value of the displacement modifier it has. The default value is set to 0.0001, but you can slightly increase it to get rid of the abutting facets issue you mention. Try to keep the value reasonably low so the decal doesn’t float above the surface.
Let me know if there’s anything unclear!
