Non Opaque Materials on Skeletal Mesh

Hi everybody. I’m quite new to UE4 (I’ve been working with UDK for few years) and still struggling. At the moment I’m working on projection mapping solution made with UE4 and I’m stuck. I’ve created BP class for my 4 corner plane perspective distortion, but my material shows up on this skeletal mesh only when it’s blend mode is set to masked. If i set it to additive or translucent it becomes entirely invisible. I have no idea what I’m missing… Please help.
