My LaunchPad materials don't show in when rendered. They show when I'm in textured view, but if I change to Material view, rendered view, or make a render the launch pad turns white. The materials are there, and if I'm in edit view and select different faces of the launch pad the correct material gets highlighted in the list. The rocket and landscape are rendered correctly, smoke too, but not the launch pad. I even went back and tried assigning the materials again but made no difference. Like I said if I'm in textured view the launch pad appears correctly colored, why that would be I don't know. Any ideas? Still on 2.79(hopefully I will get a response on how to get 2.8 working soon).
That's really peculiar -- I've never heard of an issue like that before.
Were the materials for the launchpad created in Blender internal? If so, they may have to be converted to Cycles materials before they'll appear.
If that's not the case, the only solution I can think of is recreating the materials, and if that doesn't work, recreating the model. You could also try the fix specified in this BlenderArtists post.
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.
That's a bummer to hear, but I hope you find an easy way to upgrade soon. I'm glad you enjoyed the course though!
