I am in need of help. I was trying to complete a smoke tutorial, but I needed to update Blender. After I had updated to 2.82, I had put in all of the desired values into their designated slots. I pressed Bake, and afterwards I tried to look at the results through all four Viewport Shading displays (Wireframe, Solid, Material Preview, and Rendered). At first I could see the smoke in Wireframe and Solid, but only if I don't place a Principled BSDF node. If I do, it is invisible no matter what.
If anyone has any suggestions, please let me know. Below is the screenshot. The emitter is in the red circle, a small plane.
Edit: I searched some more on the internet for answers. It appears that I have a Graphics Card that is incompatible with Blender, a Radeon Pro Vega 64 16 GB. The only graphics cards that are supported are from NVIDIA, Intel, AMD, and Macs with software with an IOS version of 10.12 or older. That is most likely why it shows up with the message "No compatible GPUs found for path tracing" when I try to render the smoke with CUDA or OpenCL. The CPU works fine, so that is why only Cycles works. However, even if I switched to Cycles and CPU processing, the "Render" Viewport Shading Display just fills up with blocky black and red pixels, instead of a single cloud.
Edit 2: I believe I found the solution! I now was able to see both modular and replay in WINDOWS rather than Apple, but now I found out that it renders the same image over and over again when I wanted to hit Render Animation. I created a new question that is more related to that rendering issue, rather than this Viewport issue.
