Adding a new layer mask to an existing Landscape

[Amerio.Stephane]

Hello,

I have a terrain which was made with sandworm, and later manually edited inside the editor. This terrain was made with only one layer mask at the the time, and it was manually painted inside the editor. Now we need to add multiple additional layer masks, but how can we do this without having to regenerate the landscape ? (I don't want to lose the manual edits if possible).

Bonus question: this landscape will be added to the same world where an existing Landscape with 15 masks already exists. Ideally, I'd like the masks to match (names, order) on both Landscape. Is this possible? any caution I should take?

It will most likely be necessary to use a dedicated world for terrain generation as Sandworm removes previous results before committing a new one. For this reason, the additional layer should be generated separately and then manually added to your base world. This approach will allow you to preserve your manual adjustments while still incorporating the new landscape map layer.

Please also ensure that the same projection and origin used for generating the base layer are applied again. This is important to guarantee correct alignment of the data and its position.

The layer names and order are stored within the ObjectLandscapeTerrain object, so the additional landscape layer moved into the base world will inherit these parameters. All existing data from the base layer map will be blended accordingly.

Please refer to the attached video for a visual explanation of this behavior. I hope it clarifies the process.

Thanks!
