Highlights do not show on mobile devices

[OnceCrowned]

Reproduction Steps

Apply a highlight to an object. Then join on a mobile device (iOs or android iirc) and it will not appear. This has occurred ever since the introduction of the highlight object.

Expected Behavior

I expect that the highlight outline displays.

Actual Behavior

It does not appear on mobile devices, but appears on PCs.

Issue Area: Engine
Issue Type: Display
Impact: Low
Frequency: Constantly

This has been a problem ever since the introduction of the highlight object. Anyone have any workarounds? Any updates?

Here are some developer forums to help you with your problem.
This will be related to what you’re trying to fix I assume.

Hope this helps!

Highlight feature not working on actual mobile/tablet devices

I have played with the new Highlight instance, and although it works in Studio, in Emulator, and in Game on my computer, once publishing and testing with an actual tablet or mobile, it does not show up. Is there something I am unaware of? Has this feature not fully been released officially yet? Anyone else having this issue? If it does work on mobile and tablet, please also reply so that I know that maybe its my specific application of the highlight.

Highlight Doesn't works on mobile

Well, the title is very self-explanatory, I made some highlight Instances but none of them works on mobile , there’s anyway to fix it?

I tried the workarounds and I am still getting complaints

this has been broken since release and I am floored it wasn’t even acknowledged until a week ago lmfao

Can confirm, still broken in Android anyway. Works fine on PC, Xbox, etc.

“Highlights do not show on mobile devices”

Yeah, pretty sure it’s a Roblox bug.
Something that only Roblox can fix.

I also experience this issue, it’s very annoying.
In an attempt at verifying if this is a bug or not (performance saver) you can start the mobile emulator in Studio and check if they render. This is not guaranteed, however, as they both run differently.

I think it’s because of graphics quality. Weak devices don’t have much quality to make highlight outlines visible.

[knightmb1 (KnightMB)]

I tested it on high-end mobile, the issue is still there even on the highest detail settings unfortunately.

Not fixed still. apologies for the rotation on the video

Windows 10 PC

Iphone 14 plus (ios 16.6)

The only work around for mobile is to use a transparent version of a fill color. The outline will still be visible on PC and the fill should be visible through the walls for Mobile.

Hey , this issue is still going on

[Pseudosuper]

Any word on this? Currently still an issue on mobile devices

[OnceCrowned]

[imonurspeeddial]
