Hey hi, glad you liked it !
-For the gun, no problem, I can work on something !
-For the low res, if you want, I can work on upscaling entities to hr, using a process I've been using on robotarmy, and soon aircraft (this week I worked on a script to overcome the hardware limitation of upscaling large animations with ESRGAN, the AI upscale program I'm mainly using), so I could use this process on helicopters too if you think it looks good (it's the best process I found, short of re-rendering)
-Note that at one point, I tried to add player color to the helicopter camo, but 1) It didn't look good and 2) it didn't take apply_runtime_tint into account, despite me changing the force of that particular entity in a script, and I think it's because it's an entity with force and not an entity with owner... But it didn't look very good anyway, so whatever.
I have a long weekend starting tomorrow, so I could have some time for all that :)
