@fantonrko345 It is all part of the modelling process.
I created the video above that Belidos posted above. You will need to able to make basic models in order to make this work. Either that, or you will need to be able to import models into your 3D software of choice and add the line yourself. There are some shaders that can do the same thing, but, I wanted to create models that didn't require shaders.
I have a few extra models that didn't actually make it in to the cartoon pack. Are you after anything in particular? If i have it made already, I will send it over.
I will state though, if I don't have it made, I am not looking to take on any extra work, so, unfortunately, I won't be able to make anything extra.
Cheers
Jay.
