In Blender 2.8, I am trying to create a .png file of my scene. I have been using Render > Render Image but I don't get any reasonable result (either all dark, or colors wrong, etc). I have tried various combinations of engines and settings using the 'Z' hotkey, as follows, but I keep getting results that are obviously bad both in Viewport and in the final rendered image.
My question: what settings/engine/whatever do I need to use to both (a) get the light/lamp working and (b) get an image that looks right and (c) having something that works as a final image?
This is what I am starting with, set to "Render" (from the 'Z' hotkey) with the Workbench engine. Problem = the light/lamp isn't doing anything:
In the next image, I changed the engine to Eevee. Now the light/lamp works, but the text and green color are gone.
In the final image, I changed the engine to Cycles. Basically the same problem as picture #2.
Thanks in advance for your help!
