I need a hollow sphere for my skill, I know that it is possible to make a union, but even if it is hollow you cannot stay inside it with the cancollide activated (and I need it to be activated, so the player cannot escape) , and you can’t use meshpart either (the sphere is no longer hollow), so I made a sphere in blender and tried to use plugins to import to roblox studio, but this happened:
This isn’t really scripting but, for the sake of helping, here is what I’d do to try and sort this situation.
First of all, you want a solid sphere with a hollow interior, make the sphere in blender and add a solidify modifier to it. That will give you a sphere with a juicy bit of thickness to bite into.
Secondly, you want accurate collisions on the interior. Roblox Approximates these and iirc it should do the inside of a sphere as well as long as it has thickness (which you gave it with your solidify modifier).
Import it as a normal mesh part and it should work fine.
I’m not sure quite how well this solution will work without trying it myself for ages, but this solution seems to work.
