Hi,

in my tweaked ancient profile stacking leave blocks get generated next to buildings, which are they more worn than the leave would suggest.

Well a picture describes more than a thousands words could do:

Slightly related, sometimes you get a layer of air between the blocks and the buildings:

Here is my adapted profile: https://gist.github.com/tyra314/aa3ce4d64c26dc719c1ff6ad9d1f0e14
I'm using 1.10.2 with 0.0.13beta

I changed those values on purpose in the first place. However, changed them back and I think the problems persist, but you don't see them as explicit as with changed configs.

• I still see the gap:

• And I see the leave pillars.

Maybe rephrasing, what I think is the problem helps:

Those leaves at the walls of buildings should look like climbing plants, right?
And in general climbing plants need something to climb on. Therefore, when the
worldgen for example decides to gen a building even with ground, I wouldn't expect
climbing plants to be generated. Instead bushes would work well.

Oh, and a random suggestion, I always mix different leaves - oak and jungle blend well in vanilla textures -
and fences, such that they look like the trunk. :)
Like this:

Those variant leaf blocks are a cool idea. I will do that. I have not seen any of the other problems though

The leaves may even end up flying:

I'll check these out. That gap is weird. Haven't seen that yet. I'll see if I can find that in any of my worlds

For the high leaf blocks I think you were using old ancient configs and didn't delete them when upgrading lost cities. The corrects value should be:

# Chance that leafblocks will be generated at the border of a building and a street [range: 0.0 ~ 1.0, default: 0.05]
S:randomLeafBlockChance=0.05

# Frequency of leafblocks as seen from the sides of buildings [range: 1 ~ 8, default: 6]
I:randomLeafBlockThickness=6

Can you check that these are correct?
