transferring layers from zbrush

I was poly painting in Zbrush and had certain parts of my texture in different layers, was wondering if in Zbrush there is a way to export the individual layer out of Zbrush and into photoshop. Now if the solution is that I just turn the layer that I want to export on and the turn off the other layers have tried it the thing is if say i have painted green dots on that layer i will get the green dots and but the background poly paint of that object so is there another way to just get the clean selection of that layer
