Hello
Don’t know what I’ve done, but my landscape material have begun flickering like this:
When I select the landscape it stops flickering.
Anyone knows whats wrong?
You do not provide much information so it’s hard to help. First: Which version of the engine do you use? Custom source build or precompiled?
Then, how did you setup your material? A screenshot would be nice.
Precompiled 4.7.2
Screenshot of the material:
Looks to only be one of my layer blend materials that is flickering…
I have the same problem 
Still need some help with this.
I think it has something to do my Tessellation, but don’t know how to fix?
Exactly, it is tessellation. Well, I just re-did the material without having tessellation and it does not flicker. But then, I need tessellation. Cant have?
If it’s ok for your material to have a lower displacement map height, try decreasing that value.
It work for me, but unfortunately I “need” to have a certain value for it to even start to be visible, so that’s too bad
Another solution that might work is to avoid intersections through the added height, if possible.
If you limit your world displacement value to anything above 0 before plugging it into the material output node, the flicker will dissappear. You can set a “Min” node to .01 for example. See example below.
for me it’s not work, I tried also without tesselation
I set Negative and Pozitive ZBounds Extension from -100 to -1 and problem solved.
THIS WORKS GREAT! thanks!
