why isn't your template transparent
cus it's dumb
but if you use the magic selector thing in paint.net it'll get rid of it plenty (that's what I did)
you'll probably have to set that little slider a bit above 50 tho, maybe 55 or 60, so that you don't have to delete smaller parts left over yourself
p.s. this is not directed at you specifically, because ik you know how to do stuff
just information for those who are less skilled
