Developer Notes

The temporary workaround is to delete the landscape components affected, and replace them by using the add component tool.


When using the Retopolgize tool on a landscape that is utilizing the Landscape Grass Tool, any pre-existing grass types will begin to float and transform their locations.

The only way myself and the user have been able to resolve the issue is to delete each landscape component affected, and add a new one in its place.

Steps to Reproduce

2. Select the Retopologize tool.
3. Click and brush each landscape component for few seconds.
