First, I just want to say that if you're going to show off the terrain generator, show off terrain generator. Seeing the shaders mod just makes it harder to see the terrain generation.

Second, the music is very distracting. I'd rather hear you talk about what you are seeing than music like that.

Third: the terrain generation. For all the hype I've been seeing, this was disappointing. In the Mesa area, I saw perfectly flat striations. The only time I saw cliff faces was in the Mesa area. Everywhere else, I did not see any overhangs, I just saw "stepwise pyramids". There were lots of 45 degrees slopes, and very uniform height changes.

As someone who lives up at 4000 feet, in a 5 mile across flat plains, I can assure you that mountains do have flat areas. Seeing nothing but height changes does not fit "realistic".

I will try and contact him cause if he also has in depth knowledge about how to create the terrain with it he will most definitely not be frustrated anymore

• Terrain with overhangs generated using 3D noise
• Multi-octave ridged mountains (possibly combined with the above technique)
• A cave system overhaul with tunnels leading to stalactite and stalagmite-laden chasms (unless we want to support other cave mods)
• Alter the three-layer cliff biome so that rather than three distinct heights, the three layers slope around connect (Still need to figure out the math for this, but I think I'm close)

simplex vs perlin, the benefit comes from simplex being a lighter algorithm.

The algorithm in this case is OpenSimplex (very similiar in 2D but a bit different in 3D). The concern is less about performance and more about appearance. Perlin is an older algorithm that tends to exhibit visually-significant directional artifacts. This can be seen in-game as mountains, valleys, and islands all lining up north/south and east/west. Of particular importance to a project like this is visual isotropy: for it not to be easy to pick out an underlying grid structure by looking at the alignment of features. In fact in most projects, I'd say it takes very specific cases to warrant the use of Perlin over some of the newer more-artifact-free noise functions, and there aren't any of such specific cases here.

On a note about performance though, it turns out Simplex and OpenSimplex can be optimized in a way that Perlin cannot: bulk-area evaluations. Because the contributions from each lattice point are combined using addition to achieve the final result, one can generate a list of every lattice point that will contribute to the area within a chunk, and process each lattice point individually rather than re-computing the geometry for every point that needs a noise evaluation. Should performance be an issue, this optimization is something that can be implemented.

Also keep in mind that OpenSimplex is already present inside this mod. Before Ted disappeared forever, he merged a pull-request containing, among other changes by another contributer, a replacement PerlinNoise.java that generates OpenSimplex noise instead of Perlin noise. He never built it and posted it, but it was in the github repo by the time it was forked for this project, so everything you're seeing in the version being worked on right now (besides caves and the handful of stuff being generated using cellular noise) is OpenSimplex.

If you're referring to the various plants that have generated on the surface, I'm pretty sure that's typical PMP behaviour and not a bug at all. In fact, I just had a quick look at the default 'decorator' config files for PMP, and there are about 20 or so different plants that can spawn on Mushroom Island biomes.

If you'd rather not have any plants generating on Mushroom Islands, you can go into the \config\plantmegapack\decorators folder and tweak the settings on a per-biome basis.

• RTG has a 'T' in its name; RWG does not.

Lmao, this gave me a laugh.

Yes, coastal cliffs are planned for the future, but they might end up being an addon to RTG instead of being integrated into core. Still too early to say one way or the other.

Yes, we're really struggling with getting GenLayers integrated into the rest of the code base. If anyone has any experience with GenLayers, we'd love to hear from you.

The main differences between RWG and RTG are:

• RTG doesn't add any new biomes; RWG does.
• RTG generates vanilla biomes; RWG does not.
• RTG uses OpenSimplex noise to generate its terrain; RWG uses Perlin noise.
• RTG generates scattered features such as Desert Temples, Jungle Temples and Witch Huts; RWG does not.
• RTG is compatible with most mods; RWG is incompatible with many popular mods, especially mods that rely on the presence of vanilla biomes in the world.
• RTG is in active development; RWG is not.
• RTG has a 'T' in its name; RWG does not.

Rivers, yes. The rivers in RTG are long and winding and usually end up running into a larger body of water, including oceans.

As for oceans, well... they're realistic in the sense that they're a huge body of water, but that's about it. We've experimented with some different types of ocean floors, so maybe that's something we can introduce in the next release. We're also experimenting with tropical islands in the Deep Ocean biome, which also include volcanoes... but we're not sure how they're going to fit into the mod just yet.
