Issue with artifacts against an emissive plane?

Hi everyone, I’m currently new to game development with a friend (we started about a month ago). We currently have a whole level built and functioning well but we are in the end sectors of fine tuning our lighting. We have an issue where the emissive glow we have set onto a plane is causing aritifacts on the edges. Is there any sort of fix for this or possible reason as to why this is happening? The glowing planes are seperate from the mesh but in the same blueprint not as child actors, lmk if you have any questions

Hey there @Shinjuku007! Welcome to the community! This looks like it could possibly be coming from Anti-Aliasing. Temporal AA types can sometimes cause artifacting of this nature. Could you attempt to change/disable your current AA and see if the artifacting changes?

Thank you this seemed to work, I disabled TSR and tried each one setting individually. MSAA seems to generate those jagged edges on the sides and TAA seems to be the best option disabling the artifacting I noticed. I selected Temporal upsampling, TAA, and Custom Depth with TemporalAA Jitter which made everything more stable, is this a safe option to use? I do like MSAA but it just makes edges too jagged compared to TAA.

Great work! Those settings should be fine! As long as you’re not building for mobile, you shouldn’t have any issues with any of the AA setups besides possible artifacting like before. I look forward to your take on the backrooms style of game. Let me know if there’s anything else I can assist you with!
