Converting meshes into unions

Help and Feedback Game Design Support
#1

I have seen many posts about transforming unions into mesh parts, which is obviously more useful for most things, but how about converting a mesh into a union(even if not at full quality)? I’m sure this sounds stupid, but I am just asking this question out of curiosity if it can be done. I can’t see how it would be possible, but I thought I would ask. It would be very cool to be able to perform Union operations on a mesh-like part.

Thanks for reading my silly question, ExcessEnergy

There is no way that I know of to directly convert a Meshpart into a Union. There are ways to convert a Meshpart into triangle Parts, and then into a Union, but that’d be such a mess of geometry that I wouldn’t imagine it working well at all.

All things considered, performing Union operations on a Meshpart is much easier and more efficiently done in the modelling software - for instance, Blender’s Boolean modifier does everything the Union tools can do and much more.

I didn’t expect it to be possible inside of studio. Guess I’ll just stick to blender.

I just thought it would be cool to be able to slice and dice meshes. Lol

Thanks for the confirmation.

That’s kind of impossible since unions contain history data that lets you separate them, while meshes don’t have such data.

I thinking you could possibly use math to convert a mesh into many small parts connected in a union. But I don’t think this would work very well.

Here is the model link of this (i edited it in the screenshot)

i know this is a pretty old discussion, but ive noticed a similar situation with this crystal union that has been floating around on the roblox studio toolbox. i think it might have something to do with older versions of roblox robloxapp-20240624-1831349.wmv (1.6 MB)

A year later, sorry for the necropost but you both are wrong.

These are done with using preset Parts in Roblox Studio. As of now(jan 7, 2025), unionizing Meshparts is not possible. Perhaps in the nearby future.
