I created a project in Unreal Engine 5.4 however after starting the editor I’m getting a very weird artifact, it’s like a shadow to the right of my character and it is not a tail, it is not a ghosting behind me like normal ghosting issue, it is something that is always on the right of my character how can I get rid of it ? the ghosting is always to the right and lower of my character and it is very present and noticeable during playing as you can see in that screenshot it is in front of me not behind me it is always on the right regardless of my position or Direction ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/4/a/2/4a2999ea19b5b2b9bc795acedfc4eb76bd9b0904.jpeg) [![](https://d3kjluh73b9h9o.cloudfront.net/original/4X/b/c/4/bc49715be8ef98f4ac8ff4099d4358b933fbcae5.jpeg "weird artifact on the right of my character in my Unreal Engine prototype") ](https://www.youtube.com/watch?v=ooMYyrvTG8Y) ---

no idea. but i wonder if it’s a postprocess that is doing something with the depth channel and doing it wrong. also your game is looking good. and the video is much better than the screenshot to understand the issue. ---

thank you so much the environment is actually a free asset on Fab it is called stylized Egypt, there is post processing in the scene but I’m not sure which setting is responsible for this artifact ---

try disabling post the postprocess material, or the postprocess volume and see if that helps. if it does then disable each postprocess material individulally. and then you keep testing the suspected material. if it’s not postprocess youll have to look for something else. ---

disabling the post processing does not remove the effect, however it changes it, if I remove the post processing now the ghosting sink a little bit lower, but it’s still on the right of the character. disabling all the lights in the scene does not change anything ---

I think something is off with your characters motion vectors, and that it is likely being generated by something you are doing in your animation. We can confirm this by disabling Anti-aliasing, motion blur and any other temporal effects like Lumen temporarily. Then, if the ghost disappears, we can be confident that the motion vectors are wrong, causing the compensation techniques used to prevent blur are not working as intended. You can also use the motion vectors debug visualizers but they can be a bit tricky to parse. Incorrect or missing motion vectors are the primary cause of ghosting artifacts.
