Then reading (Seach: Glass), the past threads and realizing. Why would anyone put a reflect nod attached to reflect color, value. Refract nod attached to Refract color, value. That kills the CPU and their is already Reflect and Refract with values. I put a reflect nod on reflect color, value nod value to 1.000. Although 0.2 is the default. I had to stop the render. Was hard on my computer. Even on value 0.2.
