Another displacement experiment. A spherical height map was used for displacement. The height of the mountains is very much exaggerated. Displacement is coarse and there are also errors. Once it works correctly and has a fine resolution, we can create planets.

@Horo:  Both of your previous images are very interesting.  I like the results.

Been also experimenting a bit with displacement, which works without crashing Bryce if you set the render priority to Low before you displace.

Thanks for this bit of information, Horo.  I was having nonstop crashes during spot renders, but this fixed it. 

Incidentally, if this is a problem and your scene is crashing right away when you open it, you MAY be able to salvage that scene if it loaded and proceeded to do a render if you can quick click somewhere to cancel the render, then make this fix or eliminate the problem item.

Another displacement-related issue I had, with a workaround:  I applied displacement to a sphere, and noticed that during rendering, it was rendered squared off and resembled a cube.  However if I re-render the area with spot-render, then re-render, it renders correctly.

Is it possible to use the results of the displacement as the negative portion of a boolean operation?  I tried and couldn’t get it to happen, but I’m not sure if that’s because it doesn’t work that way or if I was just doing something incorrectly.

The links in the post from Stephen might offer some insights, seems he too has taken an interest in this very topic.

Start Bryce first, then load the file. It will not start to render automatically as if you double click on the file, which then launches Bryce.
