Texture flickering on large scale objects

Build type: build from official source https://github.com/EpicGames/UnrealEngine.git

Build version: 4.11.2-0+UE4

Detailed description of the issue: I’m experiencing heavy flickering on large scale objects using UE4.11 which was not there during 4.10. The Windows version works fine without any issues on UE4.10 and UE4.11.

I’ve tried a couple of things to solve the issue but non of them worked:

  • disable occlusion culling
  • adjust bound scale of the object
  • project rendering settings, optimizations, clear scene which did not change anything when set to disable but made it worth on “clear on far plane”
  • far view plane set to 0

Running UE4 with opengl3 or opengl4 option didn’t change anything either.

UE4.10 left and UE4.11 right

Repro Steps

  • create a new project with default scene / starter content
  • change skybox scale to x1000 y1000 z1000
  • leave all editor and engine setting at default

Hey -

I reproduced the flickering you mentioned and a bug report has been entered, UE-31232 , to investigate this behavior.

Cheers

Just a feedback… it works correctly on UE4.17.2 again!!!
