This weapon was made in my free time to go through the StemCell spec. It's supposed to be a cheaply made and jam-prone cyberpunk blow-back SMG.
Because of the requirements of the workflow, the end result is a mesh that has two versions:
DCC: 75k, Spec/Gloss + Displacement, Subdiv ready.
Real-Time: 15k PBR Metal/Rough + Height.
Textures are 4k for the main body, 2k for the mag, compensator, and interior, and 1k for the handle. Removing all hidden faces can get the mesh down below 10k and remove a draw call.
I'm not a mechanical engineer, so I chose a balance between modeling enough internals to make it feel fleshed out, but I was in no way under an obligation to make something that was fully functional.
Big thanks to Jesse Russell-Klarich for initial silhouette concepts, and the Due Process team for concept use.
