Hello,
Trying to run the Terrain Generator under windows 11 and it keeps crashing.
The scenario is that I have a large block of land and I've created a room to represent the block of land. when I try to run the plug-in, The pop-up window appears for a short period and then crashes the whole program
Tried version 1.2.1, 1.2, 1.1 and same issue.
Any suggestions?
Thanks

How large is 'large'? The maximum size I managed to reasonably generate is approximately 300mx300m. Anything bigger and it either takes many hours to just start or it just stops, i.e. it crashes back to the plan. Too big also has the disadvantage that any movement takes again a very long time to complete, making it virtually unworkable.
Try dividing your large block into a grid of smaller rooms and generate just a few parts leaving the borders untouched. Select the next set of rooms overlapping the previous set of blocks to generate the next part. I tried it with sets of 3x3 rooms of 100mx100, resulting in a 300x300 square. Very slow but it worked.
You will need a LOT of patience.
A very fast computer might stretch your options to a slightly bigger size. Also make sure to give SH3D/Java more memory if you haven't done that yet: https://www.sweethome3d.com/support/forum/viewthread_thread,1460_offset,0;jsessionid=F9E90267BC4ABBBA35690A13356E54D7#5802
