Setting up your Document



First load up Bryce. I'm using Bryce 5, but from what I remember, the process isn't much different for Bryce 4. My document size is set to 640*480 by default, so if you want to follow my exact steps, then you can change it by going to the [File] menu, then clicking "Document Setup...", or you can simply press ctrl + alt + N on your keyboard. Make sure the Aspect Ratio is set to 4:3. That's the ratio of your screen size, so I like to keep it that way .
When you're all done, hit the tick at the bottom right corner and come with me to the next step, where we set up our atmosphere.

If You leave antialiasing off when you render the tree the first time, it looks a lot better. It doesn`t have the white "edge" around it. You can still use antialiasing in the final picture and it works well.

Thank you for your tutorial, I was always trying to find a way where I can avoid importing objects, specially from poser. I just experimented your step by step tutorial with a poser image and the results where amazing.

that's why you render out your image that you are going to use for an alpha map WITH the elevation. like, if you're going to render it out with the camera looking down at a 15 degree angle, render the alpha map with the camera looking down at a 15 degree angle. that's where scene planning comes into play ;)

Fascinating i must say. really take the burden off my comp while rendering landscapes. One prob though, when the camera is at an ellevation, the trees look kind of wierd!
