Hi,

I'm new to Cinema 4D so this is probably a really simple question but oh well. I'm trying to create an animation on a white floor, but I get different shades of white when I rotate the camera up and down. So for example when I have a birds eye view above the animation I see the floor as white but then when I rotate the camera down to view it from the front the floor appears black, and I get different shades of gray inbetween. How can I change it so I always see the floor as white no matter what angle I am viewing it from.

Cheers.

In your material you should be using fresnel.
You can change the colors and all that by adjusting the gradient. It is almost always used on reflective surfaces.

Thanks for the reply and the link it really helped. I fixed this by turning on luminance and messing around with the gradients. Now Im wondering is there a way to change it so it becomes dark when I go to a higher angle rather than going darker when I go to a lower angle. I tried changing one side of the gradient to slightly gray but this makes no noticable difference.

I was way off when I read your questions the first time... I thought you wanted to change the color.

If you want a solid white that does not get shadows or reflections luminance is the way to go;however the compositing tag will keep things nice and white while accepting shadows and so on
here is a tutorial.

Another way of dealing with this is your lighting.... adding a sky object with a white lum material on it will help even things out.
