I benefit from this plugin enough to maybe erase the Bryce from my image map, but hoping you can fix it.

Here is the Bryce Mesa with OTG:

And here's vanilla generation of the same region:

I used an image map created from AMIDST to get a seed I liked, and used FromImage to generate with OTG. So for completeness I am going to run a test now where OTG just lets loose with a seed, no image and use /otg biome tp to find an example for us... let's see what we get:

Took a while to find one way out at Z 22000 but there it is... that was done with /mv create otgtest normal -s [SEED] -g OpenTerrainGenerator, when no such folder as /plugins/OpenTerrainGenerator/worlds/otgtest existed, totally fresh : (

I guess this biome is rare enough that nobody noticed yet. Which is exactly why I'd like to have it for my players :D are you able to invest the resources in this?

PS. I know someone must be wondering why I used OTG for a vanilla seed... remove strongholds, increase villages, tweak mineshafts and ravines... etc. It should be used on every world, no?

Update: I've located a Mesa Bryce world in a fresh generation in my single player Forge client, both up-to-date and it came out with the same errors and no other mods enabled. Sorry but I can't find an example where this doesn't happen.

Hey, thanks for reporting this. There has been some funkyness with the mesa surface generator for a while now, sometimes it gets ugly unfortunately. I've got some more important things to fix atm, may take a while before this gets prio.

Yeah I have seen some straight lines in the surface of Mesa M specifically and a lack of trees that I don't really care about. This actually looks like some chunks have been rotated, though I can't be sure. All of the edges seen are on blocks 0 and 15 of the respective chunks. Mesa M by comparison is still totally passable (and can be fixed by admins with .bc tweaks anywhoo) but this seems like more than surface gen (as if I really know) and exclusively affects biome ID 165. I'll shut up now :D

For v8_r2 I've aligned the code for the mesa surface generator with vanilla's. Found a few differences that may have been causing problems, so hopefully things should look a bit better. I'm still seeing some wonkyness with mesa's though, straight lines and corners etc. I hope it's less pronounced than before though. Please try v8 and feel free to reopen or create a new issue if mesa's are still bugged.
