A really cool software for mapmakers

I painted with WorldEdit some nice maps which I using on my servers. I'm oldfag and know WorldPainter top-to-bottom.

MCEdit is not good at now time...

Also I using TerrainControl, Chunky and WorldEdit

WorldPainter is nice, however you'd want to use that with other tools like MCEdit to get the most out of your builds

When I use it, I generate water lacunae all over the map. Does anyone know how I can eliminate them?
