I have a really nice looking crystal material using cycles applied to my object; it's pretty fast and very simple - Just one glass node. Is there any way to convert this into an HLSL shader for use wihthin Unity? My understanding is that cycles materials are left out when Blender files are used in Unity.
I don't think that is possible, at least the results will look different.
Cycles uses a completly different rendering system than what realtime graphics applications like Unity use.
