River tool doesn't work on UE 5.0. Water planes are ludicrous

Yeah, the water feature has ALWAYS worked that way for me. Makes me think it’s a setting somewhere but I’ll be damned if I can figure it out. Everything I’ve researched pretty much tells me it should be plug n play.

I have no idea why part of a landscape partition lost its texture but I did manage to fix it so yay! I had to re-create the material instance for some reason… a pain in the ■■■■ but as long as it works I’m happy.
