Strange Graphic bugs on Linux

Hello,

Today i tried, once more to cook a level on windows for use on linux (mint 17.1) how ever when i started the “game” it showed me a strange level. It seems like something is wrong with the shading. I get all colors of the rainbow.

to show you what i mean, a picture!

the colors change every time i start the level, sometimes i have one color like in the picture, some times i have many.

Over all the performance is okay, when its runing, i have nearly the same fps like on windows.
On windows the level runs fine, in editor as well as a cooked version.

My Mint system has the nvidia graphicsdriver installed (version 340.xx) and runs fine. (I play boarderlands 2 from time to time as well as portal ^^)

thanks in advance

Hey -

Just so I have a clear understanding, this is something you’re seeing after packaging the project for Linux on your window’s machine and then opening on the Linux machine? If you copy the project over to a Linux machine do you see the same effect when playing in the editor? In the Toolbar click on Settings and let me know what the option “Preview Rendering Level” is set to.

Cheers

My laptop is a dual boot setup, i just start the file from my linux system, without moving it. Currently i dont have the editor installed on my Linux partition, but i will try it tomorrow and let you know the result.

thanks for your reply

I cant get the editor working on Linux. I cant get the source. My account is connected to git-hub, but when i go to epics page i get the information that they don’t have public Sources.

Sadly i wont have time next week to solve the problem, but i will try as fast as possible.
If I get a solution i will let you know.

To get the source code for Linux you can clone the repository by using your terminal to navigate to the folder where you want the clone to download to and enter “git clone https://github.com/EpicGames/UnrealEngine -b [engine version]” and then running Setup.sh, GenerateProjectFiles.sh and “make ShaderCompileWorker UnrealLightmass UnrealPak UE4Editor.” Let me know if doing the same successfully builds the engine for you.

Hello, I am back again. Today i figured it out. It seems that I, at some point of the projekt activated the experimental dynamic indirect lightning. After turning it off and compiling everything worked out well.

Thanks for your help.
