Anchored Parts Randomly Move During Playtest

In Studio, all parts and meshes display correctly, and everything works fine when running or switching to the server side. However, during playtesting or when joining the game, the parts randomly change locations, even though everything is anchored.

Does anyone know why this issue is happening? If so, we’d appreciate any suggestions on how to fix it.

Is it Z fighting? or are they actually moving?

I would just restart studio. Test again and hope for the best.

Are the (meshes) set to DoubleSided? (if they’re unions then let me know)

They are meshes and they are not doublesided. Restarted studio nothing changed, for some reason it’s only happening on that specific area even tho in studio it looks perfect.

There is no z-fighting once I click play the parts just randomly move places

Hmmmm, maybe try un-anchoring and re-anchoring everything. Not many solutions here as I have never had this problem.

Edit: your map seems quite large, so when you play the game you might be entering the “null zone,” which may be causing the issue. Because as you said “it’s only happening on this specific area.”

Edit 2: maybe the meshes themselves are somehow “corrupted,” consider making a new one.

Hey, I tried unanchoring and reanchoring everything, but it didn’t work. Here’s the weird part: I deleted everything around it, and it still doesn’t display correctly.

If I move the exact same meshes/parts next to it, there are no issues.

It can’t be the “null zone” since we’re still within the same limits as the normal baseplate. I also tried copying the same meshes/parts to another location, but the same issue occurs.

I have more information about this issue. For some reason, the CFrame positions of the parts/meshes are not the same, even though in Studio and on the server side, they appear to be perfectly aligned. If I copy the CFrame position from another mesh and paste it on the broken ones, it looks out of place in studio, but in-game, it appears exactly as it should.

Is that fixable by my side or is this a roblox issue?
