Thank you for your answer! Just to clarify though:
(1) “With how landscape terrain tessellates, you’ll still have holes if you move closer/further away.” - you mean even before I use the transition meshes? or after as well?
(2) Transition mesh such as rocks you mean? or something else?
(3) do you have an example for such a transition mesh (a video on youtube, or even just an image) ?
