Can you use a lowres image map to bias a hires slope map?

Oh, I wrongly made my question. How wide in kilometers is first image? How
wide in kilometers is detail view?

Well, the island is - others may correct me - about 200 km wide. So the
detail view in the foreground is about 20 km i would estimate.

I don't understand, could you explain more detailed?

High!
Awesome images... as I'm also about to model some realistic landscapes, I
would like to ask you how you did the distribution of surface colors exactly -
obviously it's not a simple image map, it more looks like a Terragen scene to
me! Did you still
use 3.1 or already 3.5?

Well if you have a lowres file that you can interpolate you get a fuzzy
image map, but if you use that interpolated data to set some sort of
threshold for hires pov maps the you will get good textures, and they will
be in the correct place.

I still don't understand, maybe just make an example.

As said in the first post it uses slope patterns.
> Did you still use 3.1 or already 3.5?
Since when are slope pattern and method 3 media available in 3.1?
