Strange green light and flickering blue

Hello,
After compiling the source I have opened the empty project and this is what I see:

And after making the “SphereReflectionCapture10” invisible green light dissappears, but then there’s a lot of flickering blue light( it flickers also under the “floor” and on the sides of it):

In any tutorial i didn’t notice such behaviour.
I’m newbie as far as Unreal Engine is concerned , and i can’t get rid of this light , I would be grateful for any help.

My specs are:
Win 7 64bit;
CPU: Intel i5 3350P 3.1GHz
GPU: Radeon HD 7850

Hi Mordonus, what GPU driver version are you running on?

According to the auto update tool the newest one:
13.35.1005-140223a-168456E
Tried also with beta driver but it didn’t help.

I wanted to follow up on this since there hasn’t been a resolution yet. We don’t reproduce this here on similar hardware; have you had a chance to download the latest precompiled build using the installer from unrealengine.com to see if it happens there? If so, can you attach a dxdiag?

Out of curiosity, what do you get when running UE4Editor.exe with the other various rendering mode commands like -d3d10, -opengl3, etc?
More info is here: Graphics Programming for Unreal Engine | Unreal Engine Documentation

Thanks for response,
So I tried with different arguments and results are:

  1. -d3d10 - nothing has changed
  2. -opengl4 (screenshot)
  3. -opengl3 - it’s even worse(screenshot)
  4. -sm4 - nothing has changed
  5. -ddc=noshared - nothing either

And this is my DxDiag report: TikTokDownloader - Download Video tiktok Without Watermark - SnapTik - en


I also tried to launch UE4 on my friend’s computer and it worked for him.We have the same graphic cards but different CPUs, maybe it’s because of mine not having integrated graphics?


I downloaded precompiled build but it doesn’t seem to make a diference

No integrated Gfx on the mobo is an interesting case. Do you know what MSI mobo model you have?

It could be valuable to investigate the hardware more in case UE4 is turning out to be an early warning system that something is faulty. If that doesn’t reveal anything, you can check for possible interactions with your computing environment that UE4 might be problematic with.

For the hardware, you might try:

  • Removing and reseating the video card
  • Unplugging and reattaching the video
    card connectors to the power supply
  • Swapping video cards with your friend
    would be the best way to know for
    sure the card is fine

For system environment interactions, here are some more avenues to check:

  • Do you download all Windows updates?
  • Do you ever change your video card
    settings from factory defaults?
  • Do you use any 3rd party programs to
    monitor or optimize your system
    hardware?
  • What background programs and
    processes do you run? You might try
    out the Clean Boot troubleshooting
    process to see if it works around the
    fault that’s causing the driver crash
    How to perform a clean boot in Windows
  • Uninstalling all AMD Catalyst
    applications and drivers, rebooting,
    then reinstalling the latest WHQL
    driver might be worth a shot

Sorry for the trouble you’ve been having. Please chime in if you do figure out the problem or make any steps forward with it!

Same problem here:

I see the problem disappear when i switch Scalability Parameter called: Effects
When i send my project to friend he also had same problem.

I just downloaded this program yesterday, opened one of the starters that have pre built map and character logic, and i have the same issue. I am running off of Windows 7 home premium, i have an i3 core processor (don’t judge I’m broke) and i am pretty sure i have 6 gigs of RAM (might be 8, i forget). my laptop is 2 or 3 years old (bought it used). my guess though is it is ether a problem with our graphics cards, or drivers.

This is post process problem try zero all.

PM

Could you explain what you mean by that?

Take the PostProcess Tab → Details. When You override the checkbox tabs like: Scene Color set all to 0, Bloom all 0, Ambient Cubemap 0, Lens Flares 0, DOF 0, Motion Blur 0, SSR 0. It will also increase the fps of scene. this greens propablly comes from bloom. Make all this tabs to 0 and see the result.

Try downgrading to version 4.8 I had exactly the same issue when I first downloaded 4.9 - green light bleeding everywhere that could only be solved by removing Reflection Capture actors an Skylight.

I did some research on my own and a bit of tinkering around in the program. what i found was if you deleted “skylight” the problem went away, so i knew the problem was with the “skylight”. what i found out the problem was, was that the light color for “skylight” had to much green. to fix this, left click on “skylight” under world outline. then the details tab should show you the details of this object, if not, left click on “window” in the upper left corner of the screen, then hover on “details” then click “details 1”. scroll down to the section “light”, the find light color and change the numbers for “red” “green” and “blue”. i set mine to 4-1-255. i have also noticed problems with the world fog, but i just deleted that for the time being.

that didn’t help
