I'm back and working on L3DT again. Some of the activities include:
Fluvial erosion is finally working. It's fairly quick (ie. bearable).
The
GUI is being cleaned-up again (easier dialog controls).
I'm re-writing the tutorial page (updated with next release).
I've added a mesh file export.
Many more things to come. I don't know when the next release will be…Maybe in a month or two.
