Hello everyone,
I’m new to UE4 and I already know that I’ll be frequent visitor of this forum 
I’m looking for the best way to change the opacity(or color) of the material, but only on the part of the model - that part which is near the another object. Here is some illustration of the problem:
My actual idea is to override vertex colors based on character position(relative to another object) and use it in material editor to create for example opacity mask. Is this a good idea? Maybe you know some better solution to achieve such effect?
I’ll be thankful for all advices!
Regards,
Wojciech
