i inverted the normals of this mesh in blender to have the desired inside out mesh, though it looks like this, the bottom part is visible through the top part, this is confusing
check if the mesh has no red areas in blender
what do you mean? i dont see any red areas

I mean view face orientation
(char limit)
i get this

inside

if there’s a char limit just type these bad boys: " ⠀" (in the quotes)
Ok so the red must be removed as that is what causing the problem
what does it mean? its supossed to be inverted normals if thats what u mean
There shouldn’t be any of the red as that is what is happening in studio. Do you want this to happen?
i wanted it to be inverted so the faces can only be viewed from the inside, just like the “inverted spheres” in the studio toolbox
You want the blue to be on the inside and the red to be on the outside
how do i do that? â € â € â € â €
By flipping the faces
(char limit)
no this will make the mesh normal, i need it inverted but not weirdly like the video i posted. go on roblox studio and search inverted sphere in the toolbox meshes
I have checked it so do you want all the faces to be inverted?
yes â € â € â € â € â € â € â € â € â € â € â € â € â € â € â € â €
ok, then invert the blue faces
its already inverted, the blue faces are on the inside
How is the video you attached not as you would like it to be
the top part looks weird and not like the inverted spheres
