I am having difficulty with scaling as well I am making a T-45d helmet and I cant get it right lol can anyone tell me if the helmet second from the end (right side) is to big? because its the only size I can meke fit my head...it just looks way to big?
yes 29-31cm seems like the norm, I think it would be safe to build. I think you should build a very low def model and test it first, that way you wont waste time building one that doesn't fit, problem is - I dont know if there is a low def model for an odst helm.
