Software I used: Zbrush - 3ds max - Photoshop - UDK.
Experience: Re-topology - Low-poly - Texturing - shading.
After the Hi-Poly, I have done the re-topology on zbrush to export in UDK.
I have done a render to texture for Diffuse, Normal, LightMap and Mask, with 3ds max; Specular and Emissive map with photoshop and created the shader on UDK.
