I checked out that post and tried it too, but those settings were already set to the way the post described.
I found it in the end though! Somehow the material colors got reset, and where back to white. Why they still showed correctly in texture mode is weird. I was searching through each tab checking and double checking every thing when I found the colors had reset. If I hadn’t been following along with the videos I would say I forgot to set the colors in the first place, but I was doing everything with the videos so I know I had. Ah-well learning experience!
On a less positive note, looks like I’m stuck with Blender 2.79 as I just received a response that my graphics card is no longer supported in 2.8, I kind-of liked the idea of having collections to keep things cleaner looking, and easier to find in the outliner. Need to upgrade my whole setup anyway, not that I can afford that anytime soon, as this little scene takes 6.5 hours to render on this machine.
Thank you for your help and this lesson.
