As long as the original OBJ 3D Mesh can not be extracted and distributed I do not see ho it would violate any license terms. What you make with your renders is yours. Now just get to get this bad boy on the market
Kidding. One request for you though. When you're making the mat files for the armor, can you have the reflection maps as an option? I prefer the armor to have a matte finish, and it's a pain to go through the textures one at a time to remove the reflection map. Just a request, you can tell me to take a long walk off a short pier.
