Oh it's a pain some place. But the real problem is the loss of custome scenes/sets because of the lose of the visability option for parts. Restting shaders I can do, fixing carrara I can't. I'm hoping DAZ will be magnanimous and give me a download link to C8.1.1.8.

As in I used Jack's Parkside high halls to make an underground laboranth, old abandonded rooms used for storage of long forgotten about items. It's completely usless now, as much of the constrution was dependent on invisable walls; or being able to turn visability off on overlaping sections. 

The above is a screen cap VS the render of an on going scene. It's various parts of the West park series.
