Now we need to extend the roots at the bottom to make them even bigger. Start with a new terrain. Click on the "e" on the control strip. On the right above the settings click on new. You will see the editor has now turned black. Leave your brush settings as you had them except for the brush size. Make that a little larger for these roots and start drawing a new root. Watch your preview window to see how your roots look. You can always click undo to erase your last action. Once you have something that looks like a root, smooth a bit and then move the slider up to get rid of the black and check out.

Position the root at the bottom of the tree near the trunk. If it looks very large compared to the tree, just use the / key on the keypad to resize it to match the tree. For exact positioning, press the #2 on the keypad to go to an overhead view. Move the root to a spot towards the front and then press the #1 to go back to the normal view. Click on the little blue camera dot in the top left corner to return to your working view. With that new root selected, press ctrl d to duplicate the root. You will use this root to keep duplicating and placing around the tree until you have your roots the way you want them around the base of the tree. You are going to have to rotate each root on the y axis to get them to look right as you turn them around the tree. Easiest to use the rotate tool on the top under the edit tools. You will end up with something like this...

Now we want a few branches for the top. Choose one of your bottom roots and press ctrl d and then move the root up above the top of the tree. You will have to to rotate this root on the x y and z axis so that the base is at the bottom and the branches are going up. You may want to hit the * key on the keypad to double the size on this if it is too small. I didn't have to but it depends on the size of the ground roots. Position one at the top of the tree. Now duplicate once or twice and rotate until you have the effect of branches. It should look something like this.

Once you have the base of your tree looking like you want, click on the terrain symbol at the bottom of the screen to select all the terrain's and click on the "g" on the control strip to group your base together. Now you can click on the arrow next to the word edit to choose a trunk texture for your trunk from the trunks category.

Now we'll add the leaves. Add a tree to the scene. Click on the e on the control strip to go into the tree lab. Under your branch settings, look for trunk thickness which is the second slider from the bottom on the left. slide the bottom arrow to the left until you have your trunk thickness to 2 and 2. Now click on the material button there which will take you into the materials lab. Click on the little arrow next to the material preview to get to the material presets (see below) and choose the same texture as you used on your terrain trunk. Check out and you will be back in the tree lab.

Now I would leave the tree shape to the default. We have set the trunk to very thin anyway and you do not want the trunk to pop out of the terrain trunk. You can play with the gravity and randomness to get your branches to change direction if you like. Now you want to cloose a type of leaves for your tree. Use the drop down list on the right under shape to pick the kind of tree you will have. You can adjust the size of the leaves and how many leaves you have which will determine the thickness of the tree. You will probably fool with this quite a bit until you get the effect you want. Last thing in here is to choose the texture of your leaves. Click on the materials button on the leave side (right) to go into the materials lab and choose your leaf texture the same way you choose the trunk texture. When you are done, check out and take a look at your tree to see how you like it. Hit the * key to double the size of the tree. It will be way to small. You can click on the "e" again and fool with it until you are satisfied. When you have your tree the way you want, position it in the center of your terrain trunk using the overhead view to make sure it is in the middle. Duplicate 1 or 2 times so you have 2 or 3 trees in the center. Rotate them until you have an nice effect all the way around the tree. It will look something like this...

When you have a good looking tree, go to edit and select all and click on the "g" to group your tree together as one. Now try rendering and see if there is anything you need to change. Once you have made a tree that you really like, click on the arrow next to the word create on the top of the screen and add the tree to your tree presets. It will then be available for you to use any time you like. Remember to go out of solo mode by clicking on the little red button on the bottom before you add any other items to your scene. Here is an image I made with this tree.

You can try different leaves and styles. Try changing from stacked to spiral and so on in the tree lab for a different effect. Try different textures and so on to personalize this for your different projects. Here is another with different leaves...
