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"

Static Mesh's edges where it interects flicker/sort issues when zooming out.

I have a static rock thats made up of rock meshes attached together. Its not the cleanest opposed to just having a shell. The rocks look fine in the play area but i placed some in the vista scaled to 200-300 percent. When I move back and forth the edges where I combined the rocks start to zfight. When I zoom in it gets better. Any idea whats going on?

Thanks, Luke.

hi Luke :) it might be because your rocks geometry isn't clean... Lod 0 might look ok but when Lod 1 pops in the z fighting becomes noticeable. Ue4 may be automatically generating the Lods and if the original geometry has overlapping faces then the auto generated geometry may also...

Hi! thanks for replying. I also thought it could be LOD's but I forced Lod 0 and it still does it.

What video file types can I upload on here?

Your issue is puzzling .. I honestly don't know... I just upload looks to my YouTube though I think I've seen dynamic gifs

if it's staying in LOD 0 and the materials are normal (maybe just throw on a default material to test) sorry but I haven't seen anything quite like it. It doesn't look like z fighting... more like some unexpected vertex displacement

Thanks. Ive tried basic materials.. the video is with no textures/material. its definitely a mesh thing. :(

Weird...does it do the same thing on the static mesh editor when you zoom in and out? On an off chance, it might be your camera or post processing effects
