Inverting meshes in studio, and working with it. Is it possible?

[MuffinHandler]

I want to make outlines for my pets in a viewport frame. Currently the highlight instance is not supported for viewportframes and the only official way to make a outline effect is to have a inverted mesh from blender to make the effect appear.

However that can be really time consuming. Recently I found out you can invert meshes in studio, but it has a lot of downsides to it. For example if you move the inverted mesh using this glitch, the mesh will return to normal.

Allow default meshes to be inverted

If you want to see something interesting, assign your mesh’s parent Part a CFrame with an orthogonal reflection matrix for orientation, like Part.CFrame = CFrame(0,10,0,-1,0,0,0,-1,0,0,0,-1). This is not an intended feature, however, just a consequence of the ortho-normalization routine accepting already orthonormal matrices, as well as preserving a negative determinant of an orthogonal matrix through normalization. You don’t want to use this in a game though, the code could be updated …

Allow Normals to be Flipped on BaseParts

You can already do most of what you’re asking for by feeding a CFrame with inverted handedness (by flipping one of its vectors, here the X vector is flipped): Instance.new("Part", workspace).CFrame = CFrame.new(0,10,0,-1,0,0,0,1,0,0,0,1) [image] Or alternatively, make it a mesh with inverted normals, or use SpecialMesh to have an inverted existing mesh.

I am wondering if there is a more stable, automatic and quick way to do this?

This was done using inverted meshes that was imported from blender, however that is not what I want to do. I want to invert the meshes in studio.

I’m not sure if this is possible, but doesn’t SpecialMesh allow negative scale values?

[MuffinHandler]

They do but I don’t see how that would help here

Shouldn’t making it negative also invert the vertices?

[MuffinHandler]

It just made the mesh bigger (I set the scaled to huge negative numbers, but it only made the mesh bigger). That black thing is the mesh that is too big to fit on my screen

In that case, it’s probably not possible to achieve this.

I’m extremely late but
set it to -1, -1, -1. that should work
