I'm trying to follow a tutorial for Bryce but it uses PhotoShop and I don't know that prog very well. An instruction says "Select all in the RGB channel," But I can't find an RGB Channel, and the tut doesn't explain where that is - can anyone help? Fran

Do you have the Channels palette open (Window>Channels)? If so just do a ctrl-a without chnging anything and you should be fine, assuming that the composite RGB channel and the Red, Green and Blue channels are selected. Ctrl+~ will also select the RGB channel. If you are using Photoshop Elements, rather than the full PS, I don't think you have access to that.

Sorry, I should have said, this is what I have:^^^ (see pic) and the link shows the tutorial I'm attempting to follow.

You have a greyscale image, the tutorial is expecting a colour image. As far as I can see it doesn't matter for the method - just select the grey channel instead of the RGB channel and it should work.

Oh right, okay. Thanks.

If you need RGB image go to image-mode-RGB and it will be converted from grayscale to RGB without loosing anything :) Tihomir

Thanks, but I've pretty much given up on that tutorial. It was for making roads in Bryce - I just opened Wings3D and made a nice straight road in that (plus a couple of curvy ones just in case) It seems there are quite a few problems in that tut, people have said they've tried it and couldn't get it to work. So as I see no point in banging your head against a brick wall, I stopped... But thanks for the tip, may come in handy some time in the future.

Try this simple way: 1) Fill the background layer with black&white radial gradient 2) Go to filter-render-difference clouds, press CTRL+F to repeat filter until you see the map that you like. 3) Go to filter-blur-gaussian blur and enter 0,2% press OK. 4) Go to image-adjustment-treshold the image should become black and white, press the down arow and you should get nice natural roads. 5) Duplicate the file by going to image-duplicate and invert it by pressing the CTRL+I. The trick is that one file is youre road and another is mountain around it that match perfect. 6) Make that elevation map on 512x512px, you can enlarge the resolution later in bryce on 1024x1024px or higher. Hope this is not to complicate, its usefull when you want to make waterfalls also ;) Tihomir

Is it really? Sounds very handy. Thanks very much. (hastily saving the instructions under "Waterfalls" and "Roads") Lovely. ta.
