Awesome man, thank you for the additional feedback! Yeah, the Terrain needs some love and variation for sure. A lot of it came down to time, it's partly why the terrain is so massive compared to the space actually used (it's sort of a neat effect but totally unintended). Interestingly I built the terrain off a heightmap of where I live with some added bumps heh :)
I see exactly what you are saying about jumping. To be completely honest, using a hybrid of translation with rigid body forces is just strange so if I had to redo my character controller I would probably commit to one or the other lol (forces for jumps currently). Since the longest jumps are shorter than the max jump length significantly one thing I could try is tweaking the jump force overall, I might test it out a bit :)
