I wonder if I could trouble you for your opinion on whether or not Terragen is suitable for a project I am working on.
I find it difficult to be succinct in a description of my requirements but if I give you an example scenario you should get the idea and be able to advise what is and is not possible.
A procedural method creates a realistic terrain over a large area, say 100sq km, that gives detail down to a 10m ish resolution.
This terrain is then "fixed" as a mesh rather than a procedural terrain so that it can have large features like rivers and the like manually or subprocedurally added.
A 10x10km subdivision of the large terrain is saved off and reloaded and made more detailed via procedural and manual methods to add detail at the 1m ish level, say roads and building plots for example.
This process could be repeated again for a 1x1km subdivision and so on.
Thus when an image or animation is made the 100x100 area is loaded first, then the 10x10 area, which overwrites the appropriate bit of the 100x100 terrain, and so on down the the most detailed subdivision, which is where the action will take place.
I saw an animation of a Martian scene that gave me the initial thought that Terragen might be able to do this.
What I need is that the individual subdivisions can be saved, manipulated, and reloaded into the larger map accurately (ideally using an absolute coordinate system).
If this does sound feasible?
