Something is up with the orthographic rendering mode, and I can’t figure out what it is. I think it is a bug, since I shows in perspective and shows with the emissive blue color, but not with the materials.
Take a look:
Hello Specialist89,
So when you toggle Orthographic mode, it is going to send you into Unlit mode which is why the cube is visible when you switch to orthographic. If you place a single point light around the cube in the and switch to Perspective viewmode, then you will see the cube.
Reversely, the reason you are able to see the blue material is because the emissive property does not need any sort of lighting to render to the screen. What you are seeing is expected and you just need to either make your material unlit or add lights to your scene.
Let me know if you have further questions.
Thanks,
