I'm very new to 3D coat and I'm trying to UV unwrap a model with edge selections but there are pink lines on my model that make is hard to see if I've selected an edge. They cover any selections / remain pink regardless. How do I turn this off? or do I need to do fix something on my model remove them? it's driving me nuts trying to find the answer. The only thing I can find online is that these are 'sharp edges' and I should select and clear them - but I can't figure out how to do
