It automatically uploads it as a mesh in your inventory and you can configure its settings on the page (similar to how you can configure models, shirts and pants).
So i have to export 40 seperate meshes, configure 40 seperate meshparts, make sure all 40 are moderated and then change all their settings to free? That would take hours!
Exporting them all to studio, positioning them like the second picture, and uploading as a ROBLOX free model would make these readily available to everyone. But it would be a bit of work.
I realized a lot of people liked the meshparts but didn’t want to go through the whole process of importing every single one of them using a program they are not familiar with.
So now you can get all the meshparts in one click!
What you could also do, is upload each mesh as a model individually, then make a plugin that works like CSG Primitives Just an idea, of course, but it would be pretty neat ^-^
