1. Mesh Flickering (Modular Tile) (Video Example)

   

   Topic by mister_s · Dec 2012 · Home› Unreal Engine

   I have this issue that has been driving me insane. I have what is essentially modular tiles for the floor on my level. The tiles are just a single planes (2 tris). The problem is the things keep flickering like crazy. I'm not really sure why they are acting like that. They're gigantic, but still have power of two…

   If that's the case you might be able to cheat it into ALWAYS drawing by putting a stray vert or invisible triangle far enough way (in the direction of and past the player) that it creates a bounding box that always encompasses the play area. I think that might force skip of at least some of the queries, right? Of course,…

   Indeed - like I said in your UDK forum thread, it looks like an issue with the mesh bounds and it's being occlusion culled. http://forums.epicgames.com/threads/933423-Flickering-meshes-%28Modular-Floor-Large-Plane-2-tris%29-%28Updated-Now-has-video%29?p=30832097&viewfull=1#post30832097

   I was searching the forum for help with a similar issue. I'm not 100% sure this is the same problem you're experiencing but I've been having some trouble with modular pieces showing seams in UDK. The set piece is exactly 512 x 512 generic units in 3ds and it snaps correctly in UDK as far as I can tell but when I have…

   Thanks for the input everyone. Just an update: adding collision didn't work. A single plane did work, but when I added walls and a ceiling the problem increased exponentially. I even tried a basic brush to no avail. My teacher said he found a discussion that it may be the July build I'm using so I'm going to jump back to…

   edit -- or give it quick UED collision as per ambershee's comment on the UDK thread and see if that gets it past the occlusion check

   Looks like a driver bug or something to do with occlusion queries; it looks like it happens when the hourglass moves in front of the objects.
