When I am trying to create a very large mountain that encompasses a few zones at once it is often hard to generate it procedurally because the height difference between the zones causes major stretching. This becomes even more tedious when you are using a huge number of zones which have to be constantly swapped in and out. Is there already, and if not there ought to be, a way to have it that when producing something procedurally it will take in account the zones next to it and blend the two?

I am using a 9 x 9 zones map, so there are actually 81 zones to work with, and i can keep about 6-7 un-swapped at time.

Thank you!

Forgot to add: Please add tutorials where multi-zone maps are used.

Yes, we are aware of these inconveniences when working with multiple zones. In general you must be very careful with the fractal tools and adjust the output range accordingly. Also, to be noted that if you used the same fractal parameters the generated output will be continuous even though you apply it in separate steps on different zones (they were made this way). So for example if you apply a mountain with some settings on zone X, and then apply the same tool on neightbor zone Y, the effect will be continuous.

In general, the border differences can be fixed with manual brushes (smooth, smudge) and applying the fractal effects by brushes (starting with version 1.2). Also multiple layers of heightmaps can help here as you can keep and track the changes on separate layers. Quick fixes can be made with the elevation tool (adjust the height of a terrain surface) through selection layers (only at the border) and than fixing the seams with brushes.

For future versions of Grome we indeed plan more helpful functions like moving mountains, blending one terrain feature into another, gradient tools etc.

We will also try to add more and more tutorials with time. In the mean time, if you have any other questions please don't hesitate to post them here. You can even have screenshots of the problem and describe what you want to achieve in the end, and we can have one of our artists help you by providing hints, parameters, steps to follow etc.
