I think your very confused with your terms and such.

Bump maps can be anything, what your thinkin of was a site posted that had all the different noises and how they look rendered with displacement

I'd really like to see the result you get. Or better yet, the file.

So far I thought failing with bumps was nearly impossible :D

There's two problems. 1st, in the displacement channel, you have a height of 0, meaning you're telling C4D to displace your sphere 0m, which isn't going to do anything. 2nd, on your sphere, you either need to uncheck "render perfect" or make it editable so it's an actual polygon object.

Hi, I just took a look at your file...2 problems, one is that you need to make your sphere an editable object, and 2nd is that your height was set to 0 for displacement. Try changing those two things.

Doh!...how does one delete a post when it's a duplicate?

Thanks guys :) that was exatcly it. theres just a few small stuff here and there in C4d that works different from Strata CX which i am transitioning over from. I appreciate it. I will post my new model sometime this week if not monday for show and tell. Thank You Guys!

Does C4D support normal bump?
What the diff between normal bump and SPD?
I tried SPD and it looked and feel like got more depth than the bump but i donno what is tat for.

Bump is not displacement. Bump is an illusion (within an illusion as digital 3D is flat) and will not go outside its borders. Displacement really displaces polys.

To be able to displace, there ha to be something to displace, meaning you need more polys per surface. This increases stress on your puter's ram.
SubPolyDisplacement does not need all those polys, but creates virtual ones that further subdivide your mesh. This is far less stressy for the ram, but calculation may tae its time in complex scenes with lots of polys.

Normal maps for bump in cinema can be used with the help of Remotion's paranormal plugin. ( www.remotion.de.vu ). It works like bump on steroids, but it does not do actual displacement. Renders fast, and works like a grand cru classé.
