I would love to do it with a shader but unfortunately I have no clue when it comes to shaders. So …
AAAAAHHHHHHH!!! (Scream 
)
Maybe looking at an example of a simple shader would help.
All I really want to do is to add a little detail to the terrain so that when I am up close to it I can get a little depth perception between the terrain and any objects placed on it. My base texture is 2048^2 and covers like 20 kilometers of space so … while it looks great from a few hundred meters in the air, it is difficult to look at when on the ground.
I was successful in doing this with a flat terrain (a simple quad) and I was assigning textures to a GeomNode instance then embedding the GeomNode into a NodePath and attaching it to the scene graph. If I could get a handle to the GeomNode in my EGG model then maybe I could use the old technique. Is this possibe?
