Answer. Im making this in my front room on arma2 because arma3 i don't have. Also its all the same so it can be put into arma3 after quite easily. Some of the team have got arma3 and have done tests with it. it will come out for arma3 after arma2. Thanks, SPAWN
Yep! The "hitbox" is a 3d model, of basic squares/geometry that follow the shape of the unit (in basic terms), so you can scale this to the size of the intended unit. We can have most units working, except maybe the largest of Imperial Navy Ships and the biggest "city" titans... Most other things we don't see many problems with.
Here's a WIP example. This don't include animations to the correct scale, hence the problems. However you can still see the difference in scales.
