3D Scene artefacts in Animate Pro

I have created a 3D set and placed a figure with an ortholock. Drawing layers rotated to 90 degrees to the vertical can be ‘seen’ through the figure and vertical drawing layers in both render mode and exported. These artefacts occur when the camera rotation shows the rotated layers edge on. Is this a known effect and is there a solution? Please see the exported image of the scene.http://www.cartoonwarp.com/external/3dartefacts.jpg

This might be a good opportunity to email support@toonboom.com to report this bug. It’s difficult to debug what’s going on without being able to see the original source file.
