Eevee renderer bug or intentional? EDIT: apparently i have been a dingus and not apply a texture.

The image shows blender and just a single frame i rendered from it. I originally tried to use cycles for rendering but for some reason it did not animate at all so I had wasted 30 minutes of waiting. Next I tried eevee rendering engine and then it animated fine, but it seems the plane and cube are transparent. Is this something bizarrely intentional, a bug, or am I just going insane and i got this image from a graphing calculator
Just a guess, but it looks as if the light in your scene may be set with too high a strength, washing out the results. Check to see what the strength setting is on your light by selecting it in Object Mode and looking at the Object Data tab in the Properties Panel. You can also turn on the rendering viewport setting by holding the z key and choosing Rendering from the pie menu popup. Changing this setting will allow you to see what you can expect visually from your adjustments to this light before committing to an actual render. Hope this helps.
