I created this model of the Colt M4A1 Assault Rifle (with SOPMOD Attachments) for some fun and for practice - plus this has been on my bucket list for a while haha. Asset workflow was:
1) Modelling, Optimizing, and UV Mapping in Blender
2) Exported to Substance Painter for Texturing
3) Exported to paint.NET for Texture touchups and Decals
4) Imported into Unity (URP Project) and set up for rendering
NOTE: Assets created for personal practice and skill demonstration and not for commercial use.
