Below is the classic UA 1176 compressor. Names and logos left off both m odels to avoid copyright issues. Referenced from a pro tools rig i use constantly. Needle is movable. If you plan on making it bounce to sound, make it bounce towards the left, rather right. Thats how this unit works.
Modelled in C4d R10.1. Textures made in Bodypaint 3. Exported versions available.
