I like the Noise, but, a Noise Filter Option sounds pretty neat. Will it allow adjustment or just toggled on/off. The more options you offer to the Player the better in my opinion.
BTW, Nice Rusty Tin Can. You hand-crafted the texture? More of an Artist than you give yourself credit for. I know how you feel being a Code-Centric Game Dev. I’m learning 3D Modeling & Animation in Blender. I actually enjoy modelling, but, weary of texture mapping.
