I've seen quite a few openable sunroofs, are you sure you aren't thinking of the moonroof (bigger one in the rear)? Either way, this thing's looking great!
Refreshed rear bumper --- Post updated --- Openable door but trunk and hood still fail in terms of precision and opening by themselves
have u thought of making a temporary black texture for the no texture areas? It'll make it look nicer, and you can easily swap and delete afterwards
It seems quite difficult because it requires creating a very complex texture and if I make it myself, the results will not necessarily be accurate and successful.
all u gotta do is make a dummy text in the world editor, assign to its material in blender, and use the slider to paint it black. Good practice if you ask me
I haven't found any glossy colors and plastic accent colors that can shine, maybe they shine in blender but beamng doesn't necessarily shine like it does in blender
