QuoteIf I generate a heightfield, save and then close the file... when I open it again, it needs to be regenerated 
expected behavior a.t.m.
Quoteand is different than the original
odd.  can't confirm here.
QuoteAlso if I export the heightfield as a .lws/.lwo, it immediately flattens.
confirmed.  
default scene: 
generate terrain, 
add .lwo exporter node in-between HFgenerator and HFshader, 
generate export files (a pretty cool system with the grid of objects and the scene set-up imho), 
heightfield bounding box disappears, 
hf flattens leaving .lwo b-box, also flat.  
click generate terrain, and it is generated w-in the .lwo box.
keep squashing those bugs!  congrats.
