Where's the bumps?

I'm trying to render Jupiter something like this

(Reference http://www.planetside.co.uk/forums/index.php/topic,23242.0.html and http://www.planetside.co.uk/forums/index.php/topic,23240.0.html).

My test render turns out like this, with no sign of bumps/displacement

Here's my setup.

I'm sure it's some obvious beginner issue, but I can't figure out what. Any thoughts why my render is flat?

Any other suggestions for improving the quality are also welcome!


Hm, try increasing displacement offset. If that doesn't help, perhaps create a terrain from a greyscale image and then displace as necessary. Displacement doesn't have to be arranged in the default shader box.

You need displacement by normal, would be my first idea. Can you post the tgd, so it's easier to see what you exactly did?

Turns out my shader for the bump map was projecting through the camera rather than using a sphere projection, and I had to crank the displacement multiplier on my default shader up by a few orders of magnitude.


Ah, sometimes it's something small, easily overlooked.
