Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

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.
