Example:
- Object imported from LightWave, b/w image map connected to the Default Shader / Displacement input.
Force Raytracing for the object turned ON. Shadow doesn`t reflect the displacement.

Here is the same object, same image map but now connected to the Mesh Displacer on the Mesh Modifier tab of the imported object.
No need to change the Render Method now. Leave at "Default".
The shadows are correct and reflect the displacement.
Object and map have to be very high res or it looks like this.

Remember that you must disconnect and reconnect the Image Shader from the Object again and again after making changes
in the Image Map Shader. Terragen still cannot read those changes and display in the 3D Preview.
If you forget that you might think your setup is not working.

And if you notice:
loading the image map directly into the image slot on the Default Shader / Displacement tab
gives you a different result than the Mesh Displacer.

I find I do have trouble to get the result I want almost every time.

CHeers, Klaus

ps: search for "Mesh Displacer" and you`ll find a lot of threads discussing this topic. Information is scattered all over the place.

I had trouble to see anything in the past. Maybe it was this.
