Hi Guys,
Today I would like to introduce you an application from an S2Engine very active user, Roland Strålberg:
S2Engine HD Normal Builder
This is a utility for generating Normalmaps for the S2Engine HD. It combines a standard Normalmap with a Roughness and a Specularmap into a S2 Compatible Normalmap.
Its free.
You can directly download it at:
