This is a tutorial for those wanting to know how to create a reflection map using Quixel Suite DDO and export it to UE4.

I demostrate the difference between setting up a standard Albedo, Normal Roughness, Metallic, AO Material and an RMA Packed Material

The reflection (RMA Packed) texture map saves quite alot on texture memory by packing 3 texture maps in to one map, by using the r, g, b color channels

– Roughness goes in the Red channel
– Metallic goes in Green channel
– Ambient Occlusion goes in the Blue Channel

Set the Reflection Map to (Masks, no sRGB)

Hope this helps
Cheers
