Okay I think with plane scale 1.0 Im getting waves without problem with infinity component OFF. Though its too big, but manageable with some landscape sculpting. (Scales smaller than 1.0 seems break the waves.)
Thanks for the wave tweak video, I continue now with that.
Buoyancy works wonderfully. I added a canoe to my lake with 8 test points and its very nice.
(Except water inside boat… Btw any idea how to get water out from boats inside? 
)
