Flickering in Unity VR: Fix Flickering and Pixel Noise on Edge

In this video, we go into the common issues of flickering and pixel noise on the edge in Unity VR and provide effective solutions to eliminate these artifacts:
1. Render Scale:
2. Anti-aliasing
3. Disable Emission
4. Delete redundant lights and Bake Light
5. Change trees texture to universal render pipeline
6. Increase Texture Quality

this channel is gold, thanks for your knowledge!

The problem was not solved for me with just render scale and antialiasing. When I activated the Post Processing section in the camera settings and selected antialiasing there, the problem was greatly reduced. Of course, other techniques will need to be added for a complete solution. Thanks for the tips.

[@RoadwayVR]

As I said, Render scale is not recommended as it is resource intensive(last solution). Your input regarding activating antialiasing in post processing definitely something I will take a look at it as well.

Its also more obvious on shiny metallic surfaces, so you can turn down the smoothness in the material slider, or if you are using a single texture for a mesh instead of a repeat you can edit the texture directly - lower the metallic and roughness scale on the troublesome faces and that can sort it out. Its usually barely noticeable because the troublesome faces on your mesh are so thin.

Thanks for adding this tip, it will help other people.

Hi i tried the above render scale and alaising techinique. But still i am getting the wavy jagged edges in most of my game objcts. But i saw their demo apk it not have any jagged edges. I am using their unity package only but my build is having that
Could you help me on this?

[@RoadwayVR]

which package you are referring to? Try other solutions like baking light by changing directional light or disabling point lights

[@praveenb-xr]

@@RoadwayVR I am using ARchiviz PRO Vol 8 unity package
I tried the VR Demo apk. it doesnt have any aliasing. But My unity build after so many iterations having this

[@praveenb-xr]

if I Increased the render scale it didnt fix that, only increases resolution. tried almost all of the settings.

[@RoadwayVR]

@@praveenb-xr I am sorry that these could not help you. If you find out the solutions, then I would be happy to know it as well. Please reply it back when you find out the solution.

is it work for cardboard vr also

[@RoadwayVR]

Good question,
Cardboard VR has significantly lower number of pixels compared to Meta Quest 2 or 3. So, while these techniques might still help however keep this into your mind.

[@lmvsram3477]

Noted.thank you for your response@@RoadwayVR

[@RoadwayVR]

@@lmvsram3477 your welcome :)

[@lmvsram3477]

objects are blured on distance in my cardboard game .its normal on game view..but in vr i can only see sharpen objects near by camera@@RoadwayVR

[@RoadwayVR]

@@lmvsram3477 Your problem is hardware issue not software. I propose you to do one exercise. So, play a video in youtube in your PC and move your eye very close to the monitor (sticking your eye to the monitor). You will see pixels (rectangular shapes). Now, if we have the technology to add lots of pixels in monitor in this exercise, then you wont see pixels and everything would be good.
Now jump into cardboard, Cardboard has few number of pixels and you are wearing the headset and seeing the display from very close correct? So, the only solution is to increase pixels of carboards which you cannot instead you need to buy a new good device. i am sorry but, These techniques in this video do not help your issues.
