Blending Material

Hey guys,
Thanks a lot for the feedback
I tested it on 64 quad landscape with 2k texture size and it was running on 120 fps ( in editor)
but when i use 4k textures fps drop to 40-60 ~
i think it is expected since iam using tessellation on each layer
I also want to know what’s the standard test ? I mean how big should the landscape be and how much fps should i have to consider this material optimized ? so i can start working on it.

Thanks.
