Flickering material on landscape

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?

Precompiled 4.7.2

Screenshot of the material:

Looks to only be one of my layer blend materials that is flickering…

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.

I have the same problem :confused:

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? :confused:

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 :confused:

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!
