For SR2 mobile it’s really challenging to connect say 2+set of rockets or whatever to a wing & other spots.
To resolve this I suggest a mount point tool. With mentioned tool selected you pick the point and angle of what will be attached, then grab the set of rocket(s) (or whatever) & you move it near the set mount point...and it connects much easier than the current way.
I also suggest a ruler or grid for matching points especially for large vehicles or whatever....it’s really difficult to make a little support beam or whatever and mount it to 2 sides of something...especially if it’s large.
