I went to make a single player creative world that was flat, had no caverns, ores, vegetation, or animals, but had dungeons, cabins, underwater ruins, and pyramids. However, it seemed that the lack of caverns made it so that the Dungeons did not appear. Secondly, There were still the new-skinned animals in the world. The brown cows and the white goats. I didn't see any other animals, though.
I'm now trying out having a world with the places to put the dungeons and ruins. Still flat without animals, vegetation, or ores.
I have the dungeons underground again now, but still have the new type of animals.
Though it seems that with the flat nature of the land, I am not getting oceans or lakes. which, I suppose, is to be expected.
I found the black bears also, after some flying about
did you untick all the animals (yes I do mean 1 by 1 from the dropdown menu) during world creation?
Yes, I did. Also, saw no animals other than the new models.
However, it seemed that the lack of caverns made it so that the Dungeons did not appear
Dungeons still get generated, but if caves are disabled, underground dungeons aren't connected to the surface.
Secondly, There were still the new-skinned animals in the world. The brown cows and the white goats
Oh yes, it seems that these new animals are not affected by the animal restrictions... this will be fixed shortly
