Regarding the binoculars I used actual measurements from 6x30 Dienstglas binoculars, there were of course several different models used by the army and the larger magnification ones were of course physically larger. Here's some 6x30s in use:
I'm afraid that I'm not going to re-model the helmets and then spend ages trying to re-position them, it's taken about three weeks of work just to get the equipment positioning as good as possible. Edit the relevant text file, load up the mission editor, check, repeat the above cycle literally hundreds of times ad nauseum. I could go on doing this for the rest of my life!
. The other thing with the helmets is that they've got to fit the head model and be positioned as such else you get a bit of head poking out somewhere, get it right one way and it is out another way. I actually looked at this site http://www.german-helmets.com/HELMET%20SHELL%20SIZE%20CHART.htm
regarding helmet sizing and the head size of the model is on the larger than average size regarding helemet size. If you do the maths you'll find the circumference of the head is larger that that of the most frequently issued helmet shell size ergo the head's too big
Having said all that, I'm not saying I won't revisit the helmet situation after finishing and releasing the mod but this has taken me , in all honesty, hundreds of hours of work to get this far and I want to finish and release, take a rest and then see what can be done.
Average height 1940s 1.6764m (they were shorter in those days).
Height model 1.68m - (pretty much spot on!)
Head circumference (of an elipse) model 58.24cm (larger than average)
Average head circumference 1940's from WW2 British army statistics) (hat size 7 UK) = 57cm.
Most issued german helmet liner size = 56/57cms (which fits with the average hat size for the 40s as above) and thus a helmet shell size of 64cm.
Model (liner which is modelled along with the shell) circumference = 58.53cm (to fit model) ergo a helmet shell size of 66cms (larger than average issued).
That's why the helmets look to big, short of having head poking out somewhere (as it is jagged and not smooth) or re-modelling the human figures' head size there's not too much that I can do..
And this bit from that website sums it up nicely "Soldiers who were issued helmets had to accept the helmet that came closest to their true head size. While every effort was made to do this at the time of issue, wartime photos occasionally show men that appear to be wearing a helmet that is either one shell size too small or too big."
The difference between the reality of the situation (as mentioned above) and the game is that "all" the human models have heads larger than average circumference and thus "all" the in-game models' helmets look big.
