As a long time user of procedural textures in Imagine 3D I'd like to add here that my earliest attempts at texture animation  was moving an object with an unlocked texture applied to it through Imagine space and watching the texture change as the object moved thru it. Could that be what's happening here? The procedural applies to Vue world, and every place you move it [the procedural terrain] to in Vue World makes it appear different. Is there maybe a way to lock the procedural  to the terrain? Doubt it works eggs-ackley the same way but I believe the theory is similar.

 

Once in a while I look around,
I see a sound
and try to write it down
Sometimes they come out very soft
Tinkling light sound
The Sun comes up again
