I need a dummy thats my size, so I have accurate prints, but I cant afford armorsmith rn, so is there a way to get a dummy? or can someone make one for me?
Are you talking about a physical dummy or a virtual one? As far as I'm aware, the simplest way to scale armour to a virtual mannequin would be to buy Armorsmith. While it does cost money, consider that the cost of remaking armour pieces that are the wrong size will quickly add up to the cost of the program.
If it's a physical dummy you're looking to make, a popular method is the duct tape dummy method. Check you this tutorial to see what I mean by that: Duct Tape Dummy Tutorial
