Hello!
I’m wondering what would have better performance.
Lets say I’ve made a piece of plain white paper in blender and I want both sides to have faces, would it be better to duplicate the face and then flip normals or would it be better to use the double sided property in Roblox?
An addition to this, if I had this piece of paper and a boring cube in one mesh and I wanted to make the paper double sided then would it be better to duplicate the faces on the paper then flip the normals and have 2 faces having outwards or would it be better to split the meshes into 2 and then switch on the double sided property in Roblox?
Probably the same performance. Internally, setting to double-sided will still have to add the extra vertices et. al., so either you do it yourself, or you let Roblox do it. In other words, the cost is done during edit-mode when you click the button to make it double-sided.
I suppose doing it myself would be better since I can have it mixed with other meshes and still have double faces instead of mixing it with meshes in roblox and enabling double sided and having all faces double sided.
Yeah, that’s a fair point. If your mesh contains faces that shouldn’t be double-sided, then it makes sense to make the desired double-sided faces yourself.
