Unfortunately, the dirt chunk doesnât match the striations of normal dirt, and the grass wonât perfectly match the grass colour either (it seems to be set on the main grass colour from the lowest elevation)
Based on what @malley showed of the landmark system itâs quite possible to have a ânatural dirt chunkâ summon stone including striations, however I believe youâd need to have variants for the lowlands, plains and foothills grass colours (although only one for each elevation, the grass colours will match that used by the relevant elevation in each biome). Thereâs no intelligent âuse the appropriate grass colour for the level itâs placed onâ option from what I can see, rather, each of the elevationsâ grass colour is its own entry and even when taking advantage of masking you can only mask to a particular level (i.e. âthese blocks represent grass from the lowlands elevationâ)
Another limitation is that summon stones wonât match the edge blending which occurs around elevation changes, since this is handled at map generation. [side note: I wonder if it would be possible to mod it so that the game re-calculated the edge blending once the game is running, either on a trigger or on a regular basis?]
At the moment, the easiest option would be to use the dirt chunks, and remove the single top layer to use grass patches to replicate the natural look. Unfortunately this will only pass on the lowest elevation for now; if we get variants for each elevation and the dirt chunks were modified to include the striations (something for ACE to handle? @SnorrLaxZ for visibility), then it would be much easier to do convincing terraforming.
Personally, I use the chunkier landmarks such as the geyser and the rune site to hide my failed terraforming experiments. The stone chunks have proven very useful to me since the mountains are much more forgiving when it comes to matching things up; but Iâm lucky that all the things I wanted to patch up were on the bottom layers of the mountain â I suspect that the colours wonât match on the higher levels. Iâve given up on trying to change the shape of the grassy cliffs, or trying to undo the addition of the âflat stonesâ to an otherwise pristine grassy area (Iâm just going to build over the damage⌠thankfully itâs what I was planning to use the area for anyway, I was hoping to pretty it up first to inform the building design but after seeing the result and trying to undo it that backfired horribly hahah.)
Itâs a really cool feature, itâs just a huge shame that it couldnât get more time in the oven â it definitely feels under-baked right now. Luckily we can fix that through modding in good time; but Iâm worried that for a lot of players itâs going to turn the most-requested feature into a little bit of a let-down when they realise itâs not (YET) quite the perfect, intuitive, do-exactly-what-you-want-with-terrain system we imagined.
And for the record I 100% agree that single block summon stones would have been extremely useful. The patches are actually a bit more powerful and can fulfill that function with the right know-how, but single blocks would have been very intuitive, and would be a great way to level up a rookie geomancer too.
thanks neighbour!
