Why simple billboards are opaque in editor and translucent in game?

Make a new BP, add a billboard component, uncheck ‘hidden in game’, place the BP in the world. The billboards looks ok in editor, but in game it become semi-transparent without any obvious reason. How to fix it?

Hey ShiftZ,

I was able to reproduce this issue and have reported it internally (UE-26165). You can try instead to use the Material Billboard, which will give you greater control over how it is rendered. When this issue has been fixed it will be integrated into an upcoming full engine release or hotfix, and added to the list of fixed bugs for that associated release.

Thank you for taking the time to report this issue, and let me know if you have further questions.

Cheers,

This is marked as fixed in 4.13, but I’m still seeing the same problem in 4.17.

I’m also seeing this issue, now in 4.18, The workaround using a material billboard works though! thanks!

For real, 2023, Unreal 5.0.3 and still the same issue!
I have a simple material with only a diffuse and it completely vanish against anything behind it as if it’s flipped translucent.
I’m alredy using a material billboard.
