To explain what I mean, I will use a random sword mesh from the toolbox.
This was done by having two sword meshes, one light red and one white, where the white one was made bigger so it would have an outline. My problem is, I would like to make them both transparent. However obviously if I did that you would see both of them transparent together.
Is it possible to get around this? If I had to use Blender, how would I export just the outline of the mesh?
