Finished up my steampunk rifle today.. totally stoked about this. Real-time capture in 3DS Max 2012 with Xoliul Shader 2.0 .. Thanks again to the devs of this wicked awesome shader. Rifle observed from a production concept from Weta Workshop.
Edit: I made some additional tweaks to my texture in the spec map, and these new shots were taken in Marmoset. Love Marmoset. It's actually quite fun to mess with lighting, mood and a little depth of field in real-time.
