I've been adding more details for the interior. It's going to be quite different than the real Integral --- Post updated --- I'm planning to release a base model for free. However, the MK2 and two-axle will be paid.
I figured out the material stuff. The model is almost done. Unfortunately, this community doesn't like helping each other, which is why the progress is very slow. I'm trying to complete the jbeams. It takes a long time to make it flawless. I planned to make all versions ( MK1 and MK2) for free, but they don't deserve it. So it will cost around 1-2 dollars. I've bought an Adobe subscription just for high-quality material, lol. Cab tilt and openable panels have been completed. I'm trying to adjust the doors and after-crash jbeam things. Besides, creating a new engine is very intimidating. Just like the real Magnum, I will use both an American engine (Belasco) and a European one (I haven't decided what to call it for now). However, creating a new engine will take some time.
Can't believe I've missed out such amazing mod! I know I'm a month late and I may be bumping but this is worth the notice of everybody else's attention, hope modding goes well for ya!
