Really like the gun and detail on it. Don't have much crit right now but I will keep and eye on the thread and feedback
Also I am interested in the workflow you are using? This is going to be a HP to LP model right?
When I create this kind of asset I would work in this way:
High poly in max
Zbrush for detailing
Low poly in max and UV it
Xnormal for normals, AO, Cavity maps
Diffuse /Spec in photoshop / edit other bakes
so just interested if you do it in a different way?
peace and keep up the good work
