the steps are 8-bit artifacts. if you can work in 16-bit, you'll have less of a problem, but even then I believe it'll want an extra tap on the smoothing button... it's not Bryce's fault that you lose data when editing the terrain in an app other than Bryce.

indeed, the staircasing effect is because you're using only 8-bits per channel or for greyscale, and in all likelihood you're not using them all in the full range either, i.e. not from totally black (lowest) to totally white (highest). One way to reduce the intensity of that problem is to spread the range of your terrain elevation map's greyscale image across the whole range from 0 to 255 as allowed for an 8-bit value.
Project Dogwaffle has a tool for that, called 'Dynamic Range' in the Image menu. I'm sure Photoshop and other imaging tools have similar capabilities.
It's even better if you can paint in 16-bit per channel precision. Some tools (including Bryce I think) can then load this type of image. Not sure which imaging tool to recommend for that, but I'm assuming Photoshop has at least a plugin for it.

I had thought of the 16-bit version as well. I must be doing something wrong. When I save a file as a 16-bit grayscale in TIF format, it will load into Bryce in the terrain editor but doesn't seem to make any visible difference. I read in the the Photoshop help files that PS can do HDR images in 32-bit but unfortunately when I try to load them into Bryce I get this error: "An unexpected error has occurred (generic failure)"
Tell me more about Dogwaffle, please?

if you're using Bryce 5 you could use this

You'll still need some help on the PS end though.
Bryce 6 has better ability to use 16 bit greyscale images, though. In which case I'll just lerk and learn.
What versions of each program you are using would be of help.

or just call it 'open pit mining'..;) Maybe if you do the Photoshop after the Bryce render?..I dunno, I have the Gimp instead...good luck tho...

Dogwaffle, aka 'Project Dogwaffle', is a paint and animation program for PC.
See here in general:
http://www.thebest3d.com/dogwaffle
There are a bunch of reviews there too, and even a freeware version (which may have that 'dynamic range' thing in the Image menu, if I recall. It was called the 'Buffer' menu then (as in image buffer).
There are also several versions to choose from on the commercial versions, such as PD Pro 3.5, v4 (the latest, at http://www.thebest3d.com/pdpro ) and PD Particles (http://www.thebest3d.com/pdp) which doesn't have that dynamic range feature because we position PD Particles as a companion to whatever else you're using, i.e. it's meant for painting ith natural media brushes and particle brushes, and also focuses a little on painting and handling the Alpha channel, but the rest is left to the others, like layers, filters, animations...
oh and there's also a lite version of PD Pro based on around 3.5, called PD Artist - http://www.thebest3d.com/pda
Feel free to ask me or ping me outside of this if you have further questions on Dogwaffle. Unfortunately there's no forum at rosity dedicated to it. There's one at yahoogroups.com/group/dogwaffle and a few other places but the yahoo one is the main place.

PS: PD Pro is on sale this month.
PPS: in the current issue of PC Pro magazine there should be a review of PD in Tom Arah's column. I don't know which page though and which exact isue, Febr or March. I think March.
