Performance - 2 Sided Material vs Duplicate Geometry

Hello,

I’m just starting to look at creating clothing assets for my characters.
I’m making a modular system so there can be many different combinations of meshes per character, so I’m a little concerned about what impact this may have on performance.

I want to know what sort of impact 2 sided materials have on performance vs duplicate inverted geometry.

For example, I have a t-shirt, the sleeves are baggy and so if you look at a certain angle (up the sleeve) the mesh will be invisible. I can easily fix this with a 2-sided material, or I can modify the mesh and duplicate the geometry of the exposed underside.

I want to decide this now as it will determine my workflow for creating clothing assets and may save me a whole lot if time of 2-sided materials are fine to use!

Thanks in advance!

I did see that post, I guess it kind of points me in the right direction.

Since I’ll just be adding a little extra geometry in the problem areas I guess that’s the better option than 2-siding the material since most of the underside wont be seen.

Thanks for your help Luos
