How do I make a custom height map? Because I want to make a map BIGGER than 2048 x 2048, I want like 8192 x 8192
Just have 4 2048 x 2048 squares right next to each other, to make a 8192 x 8192 square. Don't quote me on that though. I may be wrong.
I believe that beamng doesn't support height maps as large as 8192. I don't think tiling height maps is supported yet either (from memory you can do it but no collisions on the extra maps, probably worth a test though) . What you can do is change the scale of the height map, if you have 0.5 meters = 1 pixel the map will be half as big as 1 meter per pixel. As for making height maps lots of software exists. LT3D has a good free version however the resolution is limited in the free version. Earth sculpter is a popular paid program for height maps.
You can always import a 2048x2048 heightmap from L3DT into Beamng and then alter the horizontal scaling (aka squaresize in the Beamng world editor). Just be cautious because this also makes the terrain painter's resolution scale with it.
Only one terrain file is supported with collision. A 4096X4096 heightmap scaled to 2 meters per pixel will give you a map so big you'll die before ever finishing it. Matching the terrain detail of a 2048 map at this scale requires revolutionary thinking.
Unless you're like @bob.blunderton and you crank out super high detail maps with super big sizes that were seemingly unthinkable with Torque3D in its current state.
The detail I am referencing and the 'revolutionary thinking' I suggest is light years different than what Mr. Blunderton is achieving. In the big picture though, you are absolutely correct in what people are accomplishing in Torque these days. My method would stick with a good ole' 4096 2mmp matching the terrain fidelity of a 2048 1mmp terrain, via World Machine. As the theory goes this could be scaled up to provide said detail levels on a 4096 4mmp map that would effectively become a decently detailed 8192+ sized map. This will require quite some hours in World Machine to even get close. Very fun and entertaining to explore the possibilities.
