Attention! The material is rather complicated but flexible in the settings. To simply change the color of the gate and save the old style - take the material from the label Color and change the color of the VRayColor / CoronaColor. Also in the scene is the text Regular and Old - they are assigned the appropriate materials (Regular - less worn out option). In addition, it is possible to edit or even disable individual effects (cracks - scale and strength of the bump, streaks, etc.). 3ds 2014, 2016, FBX, obj Corona, V-Ray
