How I got these SCARs?

What first started out as a project to explore Marmoset's Bevel Shader, spiraled out of control into finishing an previous environment project, but I'm pleased with the results. Each part of the weapon was baked using the recently added bevel shader feature in Marmoset toolbag 5. Though for the most part the bakes were pretty clean, i likely wouldn't do a full model using only the shader for baking, on account of how it had trouble tackling certain curved surfaces and cylinders.
