UE4 landscape height blend
Hello i have some questions regarding UE4's landscape blending shaders.
Is it possible to height blend more than 3 materials? From the research i have done and the errors i get myself it does not seem to be possible. One year ago another user asked for help about this but apparently no one knew if there was a solution:
And does tessellation work with more than 3 height-blended materials? There is a package for sale on UE4's marketplace called "Adv.Disp.Landscape Materials" with a landscape shader blending between 3 textures based on height-map. It looks to me like no one have been able to blend more than that with tessellation. Here is a link to my unanswered question regarding landscape tessellation blending:
Landscape-height blend error: The error that most users get (and myself) is that when painting the fourth material in an area the whole area gets the "standard grid material" color. Having the first material as an alpha blend does not work.
Landscape tessellation height-blend error: Where two textures meet the geometry breaks which result in holes in the landscape.

Have you tried setting your Sampler source to Shared: Wrap?

Thank you Mauro Robert! I removed height-blend for the grass and used it as "blend fixer" as you suggested. Now i have tessellation and height-blending working with 4 materials! I'm exited to see if it will work when i stack on more materials later on.
Summary: Some of the fixes i applied that made it work :
I consider the question solved and i'm happy that this was possible in UE4. Later on I will make a thread on polycount and post my progress on the scene and do some breakdown on materials, shaders etc.
any chance I could get you to give me this blueprint? lol. Wonderful work. I've been trying to achieve a good displacement result for a long time now. Yours looks awesome.
