To import your export into Blender....
create a save as path from exporter....
export file....I got six or seven lwo
Open Blender
Import lwo...find the TG lwo export
In Blender....make sure your import is in the list in your scene....ie: export_00x00y
It comes in
huge so....press n on keyboard and from that popup sidebar, scale lwo....I had to go...0.005 x y & z
Also under object.....transform geometry to origin to sit your terrain on the grid...it should be centered already
It is kind of janky to view, but hit the period on keypad to zoom in ....shift and mouse lmb does wonders sometimes too
Hope that helps....
I did this from a generate terrain plugged into export heightfield lwo
