Really good tool for generating normal maps. Tried and results having good quality. Also useful configuration options. Still I found a bug. When using the Tile mode and adjusting the neighbors, the data is not saved into the file. After restarting the tool and loading the project all neighbor settings are lost. I would appreciate a fix here.
Sorry, i missunderstood and thought you were refering to the issue opened in github about saving neighbors as presets.
The neighbors were already being saved in the project file, so i checked and it seems that they were being reseted after the load. I just pushed a fix to github. Once i finish the feature of saving the presets ill publish a bugfix release.
