Indeed, this doesn’t give you any extra precision overall, you’re still working with the same floating point sizes and locations as before. This just reduces arbitrary limits that randomly got in the way in edge cases before.
You still have to be aware of floating point error and work with it in mind (avoiding stacking super thin parts that would cause z-fighting, keeping your stuff from getting too far from the origin, etc) to get the maximum possible fidelity out of your creations.
Seems like there’s a problem with this BETA feature even though my friend had to relaunch his studio but it didn’t help.
he even tried using mesh part and asset manager
Roblox
Blender
Finally, SpecialMeshes will soon be completely useless.
This is excellent. I will find this extremely useful in future projects. Thank you!
Wrong. With this, I’d want to make parts 10^-6 studs wide. This will massively increase the detail I can cram in a showcase.
I think somewhere in the replies they said they’re working on parts bigger than 2048 studs. For showcase purposes, you might be better off smartly using Atmosphere to give it that ‘endless world’ effect than a giant, collisionless, and glitchy texturized SpecialMesh.
This will be really useful for my obby since I’m trying to make it as hard as possible. Thanks for the update, Roblox 
Sadly floating point errors hate that and will make baseplate shake
Special Meshes can also be used for parts or mesh that is bigger than 2048
Maybe introduce single sided planes? It may assist builders with making drywall inside of a building for example, without rendering 6 sides of a part when only 1 is visible.
I cheated
Back here for another answer, I checked myself too for many building styles and, heh, unions are cursed.
Woah, hold on, does this mean what I think it means??? Smaller selection box?!!
I think selection box size should vary per part size, so I don’t have a barely visible selection box on a huge part, and a too big selection box on the smallest part size.
Should increase/decrease on the distance between part and camera.
10^-6 is 1/1000000 studs, not a million studs. A million studs is approximately the distance between the centre of Brussels and the Eiffel Tower, whereas 10^-6 studs is about the size of a nanoparticle.
however since this exists I want to make a request.
Since part sizes can go way down to 0.001, can increment values like 0.01 and under snap to grid? values over 0.01 do snap which I find annoying that lower values can’t.
high quality modeler would like this lol
Now I do not need to negate a part anymore just to fit a thin piece on it, such as a screen or a picture on a frame!
So, the issue with this is that it makes it hard to see when parts are properly aligned: If two parts than are right next to each other have slightly different sizes of selection box due to the way they’re positioned in your view then it looks like they’re slightly misaligned, even they though actually aren’t:
We’re trying to get actual fixed-pixel-width selection outlines into Studio at some point to improve things.
I would say for the selection issue, is to just don’t change the size of it until it has reached a tiny enough size
