Surfaces (Inlets) not showing in game or Play Solo

I have some surfaces that have Inlets on them for interior panels on my Corsair.
In Studio the Surface shows fine, but in game or in Play Solo they show as Smooth.
My Settings are at 10 so they should be showing. Lighting, Shadows, Decals and Meshes are all showing fine. Not having any lag issues.

Tried a different place where I know there are Inlets (my Bomber place) and they aren’t showing there at all either.

Are the parts plastic? Surfaces don’t show on any materials except plastic, though they faintly show in studio to let you easily see what surfaces a part has.

If they are plastic then I have no idea what’s up.

EDIT: Yeah I always thought it was a bit odd how they don’t show up on smooth plastic.

Jesus Christmas I’ve been having this issue for I think near a year now. Never reported it because I suck. Now that I think about it I’m just going to use textures. But, studs/inlets can actually make some really great textures, having the smooth be substitute looks ugly. Would still like for this to be fixed then.

All my parts are SmoothPlastic, I think they should still show regardless, shouldn’t they? They make good textures. It’s an annoying issue since they show in Studio but not in-game.

I use SmoothPlastic as painted metal surfaces. Sometimes the smooth metal surfaces have shallow dips in them for strengthening/stiffening purposes. Using Plastic looks rough and smooth metal surfaces aren’t rough. The Inlets have shown on them up until now.
As stated, they looked cool in the right place.
Why wouldn’t they leave this alone? For most places it works and it made ROBLOX look like ROBLOX.
Because of rendering issues? C’mon, if you have rendering issues then set your settings to 2 or upgrade your computer!
