Part render bug

[Davidiko_v (David)]

Hello,
I was hanging out with some cframe things and i got strange bug:

Its normal part without anything in, thats script which i writed:

local p = workspace.Part.CFrame workspace.Part.CFrame = 
CFrame.new(
p.Position.X,p.Position.Y,p.Position.Z,
p.RightVector.X,p.UpVector.X,p.LookVector.X,
p.RightVector.Y,p.UpVector.Y,p.LookVector.Y,
p.RightVector.Z,p.UpVector.Z,p.LookVector.Z)

If i will write run it again it will fix and if again it will broke.
Idk how do post for engine bugs so i doing it like this

It’s not an “engine bug”. It happens because you’re inverting the part vectors:

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.
