PHOTOSHOP CC - Opacity map render glitch

I would like to signal an issue with how Photoshop CC handles opacity maps in 3D workflow for overlapping models. I have three sets of 16x16 chamfered box grids, imported as .obj, with as simple as possible meshes and corresponding 16x16 square grid of UVs.
When duplicated and distanced (not intersecting) from one another and viewed at an angle, I get the following black artefacts when rendering only, not in preview mode:
The three box grids are identical, not instanced, just duplicated, and the only difference is in their opacity map. It is not the lighting, or any other maps, as I've tried everything and the artefact dissapears locally once I remove the opacity map as you can see here:
In this last image the box grid on the far back has the opacity map removed, before it had a 100% white opacity map, so it's not in the way I'm drawing the map.
The artefact only happens when the models are overlapping and viewed at a more extreme angle, it's definitely a bug.
Contact me if you need the particular models for testing or other suggestions for the 3D working environment...and they are plenty.
