I stopped support for this add-on,
as a new alternative, I created a free Geometry Nodes setup here
This add-on allows you to add snow on top of objects.
No changelog for this release.
This extension does not require special permissions.
Works great. Using 4.2.3 Lts. Select face in edit mode, go to object mode, set coverage and height and 'Add Snow'. Works like a charm. After generating it has the snow selected, to try again, re-select the object, not the snow. A++
Update PLS!!
