I want to make a model similar to the Minecraft one but with more joints. Every body part is a separate object with it's own material, texture and UV. What I did first was create a model for the the body, assigned all the seams and generated the UV on a 64x64 image and then I exported the UV Layout, put it in a program and just marked the corners to check if it works, exported it in 1024x1024 pixels because otherwise it is really blurry and when I put it on the body it was offset by half a pixel on the 64x64 image (this was much more on the 1024x1024 of course). How would I calculate the size needed for it not to offset?
P.S. I don't have any images since it got me really mad after I remade the thing 10 times so I just deleted it...
