Exceeding '64k' vertex limit on objects

Alright, so I’m creating terrain according to a C# script because I found that it offers me more control and blends with what else I have in mind better.

An issue I’m running into is that once the terrain requires what seems to be about 65536 or more vertices, it starts telling me that I’m attempting to reference invalid vertices when I put everything together.

So, my main question is is there any way to exceed the 64k vertex limit?

If not, I guess I’ll just work my way around breaking the problem into sets of smaller objects.

If so, how do I change the limit?

You cannot, 2^16 = 65,536. More than that requires separate meshes.
