 You may notice, if you look carefully at the blends between the rock and grass nodes, that some areas of the MegaTexture appear to show the rock texture ''on top'' of the grass! This doesn't look very natural, and it's happening because of the node order.

 If you're building up a lot of layers of tiling textures, it can sometimes become obvious when a texture tiles in a particular direction. You may see repeating patterns extending into the distance when looking in particular directions, especially if all your nodes have the same orientation.
-An easy way to overcome this is to play with the {{keyname|Rotation}} value in the Texture Properties section of the Terrain Editor's property list.

 * The {{keyname|Ramp Width}} should be set to a value lower than the default of {{keyvalue|1}}, since this causes a very blurry blend, which is usually not what you want. Try a value of {{keyvalue|0.25}} and re-render the preview - try a "Window" preview as described earlier to get a full-resolution preview where you can really see {{keyname|Distribution Pattern Texture Scale}} to the same value as the Diffuse Scale, in this case we just use {{keyvalue|32 32}} again.

 * With the Rock node now positioned between the Dirt and Grass nodes, the grass will appear on top of the rocks as well as the dirt, which looks much more natural!
-=== Color changes ====
+=== Color changes ===
 Maybe your dirt texture is too bright? Or maybe your grass looks a little ''too'' green?
 You can easily fix this from the Terrain Editor itself! No need to create a new image every time you want to tweak the color or brightness, you can set this up on a per-node basis.

 Now that the rocks are set up, you can hit the Render Preview ([[Image:simplemega_previewbutton.png|MegaTexture Render Preview button]]) button again and see what effect the new Rock node has.
