Was working on a scene and decided to use forward slash / at a name of shader layer...
Immediately all layers from shaders and terrain disappeared...
Couldn't undo it but I was able to delete / and after that I did incremental save... The older save (from ~1hr back) works ok.
The incremental save does not seem to work though I think the data is there...
Just doesn't show up in Terragen..
You might wanna fix that.. Kinda sucks..
Cheers,
