Hey everyone,
I am a bit lost on this one - I am using an application called Qubicle 2 and I am trying to export meshes out of the application to Unreal 4.
Anyway here is where I get lost. I am trying to use an objects vertex colors from Qubicle 2 opposed to an Texture.
Does anyone know how to do this with Unreal 4?
It depends on what exactly you want to do. 
You can access vertex colours in your material. Just paint your vertex colours on your mesh - export everything - in your material add a lerp node - connect a “vertex colour” node to your lerp (when you use a red vertex colour, connect the R link,…) - and then add what you like to A/B
