I have two graphics cards, a RX580 for display and a Vega64 which was supposed to be just for rendering. Both cards were working with cycles in the beginning, though they were both called “Vega 64” in the rhino settings as render device.
Some time ago cycles aka raytraced viewport stopped working. It says “rendering” but the viewport stays in normal rendered mode, not cycles (doesn’t matter which of the GPUs I set as render device). After I had installed newer drivers like a month ago, the cards were called “Vega 64” and “Vega 36” under device settings and it still didn’t work. I just installed the latest drivers and now four devices are shown and still, raytraced does not work.
I tried the different devices in hope that one would work, but rhino crashes when I set the render device to one of the “Vega 36” devices. I did send in the bug report.
I didn’t really had any rendering work to do for quite some time now, so I didn’t really care. but soon, I’ll have to render again.
Hope this is a simple thing.
