Well the terrain modeller can be powerful but to get the results you get from terragen, Bryce, or Vue requires much more work. You see the others mentioned, unlike Carrara, are dedicated landscape based 3D apps. Carrara is a model based 3D app so making terrains and such are not as simple. I am not the best person to ask about modeling in the Terrain modeler, but I have had some pretty good results tinkering with it. You can get a decent sky and cloud layers, you can get a decent Ocean by not only using the Color value of the shader, but also using the Bump. Also the C2 terrain features are mostly new, so the Carrara 1 books are not good for these... I am sure that someone on here can direct you to a good tutorial or something. Regards, Paul
