Mirror Property

I think something like reflection mapping as @EndorsedModel is hinting at is more feasible:

Custom reflection maps!

For those unfamiliar with reflection maps: [image] Reflection mapping is an efficient image-based way to get the effect of reflection. The shiny surface is linked to an image similar to a skybox, which is projected onto it and distorted according to where the camera is and the shape of the surface. As far as I know, Roblox already uses reflection maps to create the Reflectance effect. It just uses the sky as a reflection map. However, this makes indoor parts with Reflectance > 0 a bit ugly …

It’s not perfect reflection whatsoever, just a custom image through which reflection is determined, but perfect reflection is really difficult to achieve in games for arbitrary surfaces and geometry.
