Problem with mountains tileset and terrain brush tool

Hi all,

I’m trying to play around with terrain tool and it works great for the few example I’ve seen online, which are all using 3x3 tiles for the main ‘object’ and 2x2 tiles for the corners.

Now I want to setup a terrain for a mountain tileset that I downloaded from OGA website:

The main component is 6x6 tiles and corners 4x4.
I’ve tried different things (below screenshots) which doesn’t give what I want.

For instance:

It gives weird/messy result:

What am I doing wrong here? Is it even possible to use ‘terrain’ tool in this case?
Any help would be greatly appreciated!

These tiles actually work as 32x32:

Now, it is unfortunately not possible yet to have layers in your map that use different tile sizes. So you can’t at the moment use the terrain tool to place these mountains, as well as have it help you drawing the other terrain types in that tileset since they use 16x16 tiles.

Ok I see it has been designed to work on a 32x32 map.
Thanks Bjorn!
