Add a billboard gui or particle emitter on top of a transparent BasePart
I’ve also experienced this bug in a large amount of games where there are particles/billboards on top of transparent parts
Expected Behavior
The billboard UI and particle effects should be distinctly on top on the part
Actual Behavior
The billboard UI and particle effects sometimes look like they are underneath the transparent part, even though they are actually on top
Workaround
The only thing that fixes this is removing the transparency on the part

From my experience, this is just a problem with the way the engine handles particles and semi-transparent blocks, and it has been this way for many years.
You can see this issue happen in different games with different rendering engines as well, it’s a very interesting common problem, which is pretty much a given in all games.
Unfortunately this is an engine limitation for now. A way I found to work around the issue is to move to pivot point on the part above the other one, it can help make it z-fight less often or not at all.
This is indeed an engine limitation at this time. While I’ll close this ticket because we are not treating this as a bug, I’m tracking this as a feature request internally so it can eventually make its way to our roadmap when higher priorities will have been addressed.
