Precious Metal Gold

[Brett]

   Just wondered if anyone might know why this keeps happening (and how to rectify it ) ?
I put some bland materials on this ring just to lower the CPU usage so I could get it into a different angle.
After I did all my gold materials disappeared and I can figure out how to get them back again.
Also for unknown reasons when my gold materials were present they somehow shifted into the gemstones area

CPU usage is the same independent of the material.
