I'm doing some work in Bryce at the moment using terrains using photoshop to come up with greyscale maps for it.  What I'm trying to work out is how to create a dome or hemisphere, I can do cones very easily using the gradient tool but I'm hoping someone knows an easy way to create something that will convert to something more spherical.

My maths isn't the best, but I think a good starting point would be to use the median filter on a "conical" gradient. That approximates integration, and if you do it twice that should get close to a circle. If you apply the filter to a circular selection, that should keep the base of the dome sharp.

open terrain - click new - choose a bigger brush and just click in the centre about 4 times.B4 256 res default gradient.

Cheers.  I'll copy that and save it for further use.

BTW does anyone know how to get the terrain editor to be smooth at high resolution?  If I put a dome like the one above on top of a square building on a high resolution the cube's edges end up spikey, if I smooth it down I end up with steps in the dome.  Any ideas?
