I am encountering some strange problems with PHC Nykta on the 01Sculp zone that I have never seen happen before inside Poser's Material Room.

After loading my character and the Nykta hair into my scene normally, I applied the PHC #18 texture to the hair and went into the Material Room to edit the shader. On the 01Sculp zone, the nodes and PoserSurface palette are inaccessible, as can be seen in my attached screencapture.

By using my scroll wheel, it sometimes toggles between the PoserSurface palette and the two nodes that are attached, but other times it does not. I have checked the other colour options and all of them do the same thing for the 01Sculp zone. However, checking the base Nykta, this issue does not happen.

I have tried closing Poser and restarting it. I tried downloading the .zip for the hair texture and reloading the files. I tried creating a new document and only loading the hair and applying the PHC shader. I tried dragging the PoserSurface node downwards in the Material Room in attempt to get everything to display at the same time. I have also tried deleting the two nodes and reattaching them manually, but as soon as I leave 01Sculp and go to a different zone, upon returning to 01Sculp the problem is back. None of these solutions worked.

I am using Poser Pro 2014 version 10.0.5.28925.

Any help of fixing the problem or an explanation of what is going on would be greatly appreciated!
