Could someone please tell me how to make realistic landscapes... instead of just a mountain surrounded in water or crap like that... I mean realistic like more three-demensional pictures. If you can understand what I am asking, then please explain what I need to do... Thanks in advance.

Practice makes perfect. You may want to experiment with some of the tutorials, just follow the link.

The fractal option in the terrain editor can add lot's of realism. Also watch out with lot's of dense erosion, because that can give your terrains the spikey unrealistic look off most basic bryce terrains. Erosion is a great tool, but don't overuse it. You can also use DEM's to create realistic terrains. I've never used them myself, but they can create great results.

A great way to learn is to look at landscapes around you that you like, or, short of that look at other people's art and imagine a place you might want to look at. Traveling helps bring perspective... Bryce is apparently named after it's ability to recreate Bryce Canyon-like terrain pics, and that place is pretty cool...!

Practice, practice, practice. :^)

The above advice is good and I can add one more suggestion. Look at landscapes and photographs of landscapes too. Magazines that feature Southwestern or American art have some great landscape pictures.

Use several terrains. It is hard to get realistic results if you are using only one terrain ( or a plain ). Use terrains at as high a resolution as your computer can take.

OOOOOOPS Plain should be plane. Sorry, please carry on.

Read everything you find at the attached URL. Use lots of little pieces and tweak. It comes but it takes practice, practice, practice. Sit down with a single element and work your tools so you can understand them, then use what you learn in a scene. If you start building a big scene you have to wait too long to see what your changes actually do. I needed a shale texture, so I grabbed the arizona texture and started tweaking the presets. I needed brown leaves so I loaded the orange and played with colors. I kicked down the specularity to make it look dull. When it was too dark in the shadows I upped the ambience. I rarely use the presets as-is anymore. Lots of objects add complexity. Use several terrains. When you want a rock add a bryce rock instead of trying to make the terrain do it. Big photo textures can help. bryce procedural wood stinks. Take a picture of your coffee table and use it or load a texture from the internet. Hope this helps:)

Aye, but I strongly disagree with electro about procedural wood! Maybe it was all my time in RDS, but Ive made a few good woods in my day. I'll try and post an example... (trails off into unintelligable muttering)

Sorry,I just meant the presets in simple and fast look fake. If you want them to look real you have to tweak the settings.

Aye, okay, you're right about that, Electro. Sorry if I seem critical, maybe I'm just critique-al...!
