why is the liveview all black if I apply Corona materials to the model?

"Why is anything black? Because no light reaches 'I'."

More data is needed to make precise conclusion and offer solution.

Image you posted reveals nothing about what you've done - about how's your scene constructed, shaded, set... ?
So do a test with same scene set/structure on another example (ie. a cube using same lighting, materials & render settings...) If it still renders black, share it here, and if it renders OK, then compare to find what's different. Might be just direction of normals or such.

Hm, it works/shows fine here (as set).


Tho, since Corona doesn't apply 'standard C4D lighting' - to have more control and natural look - add Corona Sky ('Environment Lighting')  & Corona Camera ('Standard Observer') to your scene.
Scene attached. :)

I opened your file, but the liveview is still all black except the sky. what changes did you make, man? I cannot see the difference compared to the file I sent you.

The texture files are missing in your example. So, I'm also getting a black preview which is to be expected. Also note that some metallic materials may display as back in the viewport.

Yes, textures aren't packed with the scene. Need to use your own!
My bad for assuming you were aware of this... ˇˇ

PS.
Always check with "Project Asset Inspector" for any stuff missing - which is found under "Window" menu ;)

thx for your remind. but I assume it is not only becoz of the missing textures. Here I attached a new scene with no texture in any channel, but the liveview is still black.

Tho your floor is black because of the missing texures, but I see the cube is green. but in my scene the cube is black all the time. Just check the scene I sent in the last reply.

Also, switch from Gouraud Shading to Quick Shading.

which  i think should be chnag3ed, metals are far from blk and realy should  represent their "basic color" in viewport (metall workflow etc).
so not take diffuse color but metal /reflection color in al cases
