Hey @makualteredverse!

A few questions to help get the ball rolling:

• What engine version are you using?
• Are you using Lumen?
• Do you have virtual shadows enabled?
• Is there any post processing in your scene?
• What solutions have you tried so far? (For process of elimination)

Any additional specifics you provide may go a long way in solving your problem!

Hi @Quetzalcodename

Thank you for looking.

• What engine version are you using?
  – im using 5.4

• Are you using Lumen?
  – Yes

• Do you have virtual shadows enabled?
  – Yes

• Is there any post processing in your scene?
  – Yes, only for highlighting (like silhouettes in objects)

• What solutions have you tried so far? (For process of elimination)
  – tried the changing AA method to TAA (solved the issue with shadow noise like on crt tv)
  – for flickering, still cant solve. ive also tried the ray cast for shadow still doesnt solve.

here is the fixed screenshot for the shadow noise:

here is the part i cant solve. shadow is like waving flicker

Hey @makualteredverse,

That’s great that you solved your issue. Would you mind sharing what you did just in case anyone else runs into the same problem?

Hi @Quetzalcodename

Sure.

1. in Project Settings → Rendering → Default Settings → Anti -Aliasing Method, set to TAA
2. in Editor Preferences → General - Performance → Screen Percentage for Desktop renderer, set to manual
