I know that,and I've been using LDD for years; however, from my experience, LDD's way of making instructions (the "Building Guide mode" instructions you can generate with Ctrl + H) can be total garbage for making anything an average person can legibly use, especially for larger builds. Using LDD's automatic instruction creator is like using Wordpress to code a mod: just... ...no. It doesn't work too well for large models, and it ESPECIALLY doesn't work for Technic models. (This is what the model looks like when it's completed.)
I'd totally rock a NO TEXTURE t-shirt, hell I'd even buy two. A hoodie would be pretty cool too, maybe the Civetta Bolide on it, like the Group 4 perhaps? Or the Notte, mid-rev limiter, spitting flames.
How about rubbers/erasers? Lots of people in the community like sketching or drawing, they are probably cheaper and easier to make than die cast models, and they deform over time
I hate bumper stickers but I'd totally rock a beamng sticker. Also i want that shirt with the logo on it i think it looks pretty good actually.
Okay so maybe some sort of sports jacket with beamng logos? I guess i'm just a sucker for that sort of stuff
I would love to see posters in the style of an automotive designer sketch. Just imagine a poster of a Moonhawk in this style (Larry Wood sketch of a Hot Wheels Mustang II) Or a BeamNG set styled like this beautiful card art from the HW Larry Woods 50th anniversary set
