Gaea School #2 More basics

 Basics Operations

There are some things that still cause me to get stuck. I create terrain, but then find that I'm unable to build because the nodes aren't flagged for it. 

Right-click the node and choose Mark for Export


Nodes need to be baked into discrete files before you can export a terrain. Use the Bake menu to select the appropriate nodes for baking.


I had a question about how to set the terrain's scale. It's under Project menu: Build Settings: Terrain

Terrain scale set under Terrain Definition 

For regular landscape creation, it's not critical. The default scale is 5km x 5km with a max height of 2.5km

However, for realistic scales, it really benefits you to set the scale appropriately. As the guidelines point out, Everest is nearly 9000m tall; such a giant terrain requires a larger underlying terrain tile.
