Bug regarding Mutable, “Layout Editor”
Issue: If “Resizable” Layout Strategy contains a block, it will influence the “Overlay” Layout Strategy.
Expected behavior: When using “Overlay” Layout Strategy, it should disregard whatever the “Resizable” Layout Strategy contains.

Steps to Reproduce
Hey there,
Apologies, I tested this, and everything seems to be in order; I’m not clear on what the bug is.

Hello Dustin!
We tried to replicate this on different PCs and the issue persists. Here is a little more in-depth of the steps I take, in case something stands out to you!
I’m using a data table to get all the relevant assets.
By default, it creates a yellow UV Block to modify the mesh, which is also seen in the picture. This UV block causes an interference when the Layout is set to Overlay.
It pushes the UVs out of the original packing into other UV quadrants (which is by design when actually using the Resizable block mode, I believe), but this is when Resizable mode interferes with the Overlay mode and causes this sort of results:
To get around this, I have to manually remove the yellow block seen in the first picture, before switching to Overlay mode. And it has to be manually removed for every single LOD, of every single skeletal mesh.I hope this additional information will make you be able to reproduce it. If not, we can close this ticket since it might be a local version of the engine that is already fixed in your in-house engine!
Thanks for this,
I’ve logged an issue here: https://issues.unrealengine.com/issue/UE-368801 that you can follow along.

Woohoo, thank you Dustin
