I was thinking of using triangle terrain with parts of actual terrain like Ultimate driving does, but I want it to look the best while being optimistic. Any tips or help would be much appreciated
This plugin allows you to make triangle (wedges) terrain using nodes.
If you want the mountains to look smooth, after you’re done placing wedges, export it to blender and shade it smooth. Export it back and overlay the mesh with your wedge terrain.
If your mountain area is interactive and you want smooth shading, I highly recommend turning collisions off for the MESH mountain and making the PARTS mountain invisible & collision true for the correct hitboxes.
The invisible parts should have minimal impact on performance.
for reference, this was some very simple hill terrain I created w/ the plugin.
