I’m extremely lost | I cannot understand anything | I don’t know how to do X

I highly recommend to check out the included samples. It has an example of a textured terrain on each of the pipelines, with vegetation and physics objects. There’s also an included displacement particle system scene for built-in to move the grass around. You can use and test with those assets to get a hang of how/what can be done.

If with that it’s still not enough head out to Scripting to see small tutorials. Finally, join our discord server! There’s plenty of people, including me, happy to guide you around.

World has no detail | World has too much detail

If you find yourself with a terrain with too much detail or almost none, you might be in one of the three situations:

  • Scales are too big or too small: You might have a noise layer with the wrong scale. A scale too small will compress the noise and make all ridges really close to each other. The same way, a scale too big will make the ridges to far from each other and maybe not even visible in scene. With a mesh scale of a 1000 units, you will need a scale that fits, around 400-500 units.
  • Min Max is too big or too small: The noise gets scaled according to the min max value. Scale it up and down to fit. With a mesh scale of a 1000 units, you will need a min max that fits, around 0 to 200-300 units.
  • Too many octaves: There are cases where the additional octaves will make the whole terrain over detailed. Reduce the amount of octaves or play with lacunarity and persistence to better fit your needs.

No detail

Too much detail

It goes pretty slow when inside PlayMode :(

Well, vegetation rendering is not free, and mesh can have a lot of triangles, so let’s go over some tweaks that can be done.

I want to do a custom implementation of X thing, but I can’t figure it out

First check the code and the already prexisting implementations. You might find some useful information and already written code that you can base your ideas from.

If with that it’s still not enough head out to Scripting to see small tutorials on how to make your own implementation.

Finally, worst case scenario, remember that you can join our discord server and ask any questions there!

Does it support X asset?

This is quite a complicated question. Generally i don’t own the asset mentioned so it’s hard to say if it fully works or not.

  • If the asset requires Unity Terrain probably doesn’t work since it relies on its custom solution of meshes. It’s possible to move my code to Unity Terrain but i haven’t yet.

  • If the asset relies on custom materials/shaders, it’s usually possible to modify them so that they are compatible

  • If the asset are meshes, 3d models or doesn’t require other assets probably yes!

  • If its your asset i would be happy to check out each other assets and build the appropriate changes that would improve both of those assets and make them compatible. DM if that’s the case!

Why should I use Infinite Lands chunks when you support Unity Terrain (or the other way)?

Well, I added Unity Terrain support mainly for compatibility reasons, and because I want to give the option to generate the terrain, export it, and allow users to manually modify it without the need of Infinite Lands. But here are some pros and cons of each system

  Infinite Lands Unity Chunk
Pros - Made for infinite view distance, allowing for Quad Tree structure that allows extreme chunk generation with really low impact.
- Made for infinite (or at least really high) rendering of vegetation
- Highly performant generation and rendering
- Memory friendly!
- Main branch of development, and therefore cool features will mainly be there		 - Its unity terrain therefore compatible out of the box with other assets
- You can use brushes to modify the terrain if exported
- You can export them to disk as is and use them without Infinite Lands
- It's more familiar with new users
Cons - Not familiar for new users
- Cannot use brushes or modify the terrain after generation
- You cannot export the meshes (although still export the height maps)
- It might not be compatible with other assets in the Unity Asset Store (prone to change)		 - Way slower to generate the terrain
- Doesn't handle well millions of vegetation instances
- Doesn't handle well long rendering distances
- Not memory friendly
- Not the main supported behaviour, and therefore might fall behind in some aspects

I just walked around really far and everything flickers! CHAOS!

Don’t worry! Welcome to Floating Point errors. Since you are really far from the origin, you will be seeing a lot of flickering because of how the math is done in the shaders. To solve this, you can add the Floating Origin component to your generator. Make sure that any object static or movable, has a Floating Point component added to it too! This will ensure that it is at the right position when the main character moves around.

Unity is stuck saving/reloading domain/other and I can’t work. It doesn’t finish!

There’s a weird bug hard to find and to fix because it’s hard to replicate, where unity gets stuck saving your scene or asset, and other similar actions. There’s a work around when that happens.

First open task manager and look for Unity Editor. alt text You will see two Unity Editor instances together, and down in the bottom the one saying “Not Responding”. Right click on the two instances that are together and Force Close them.

That should get Unity running up to speed again.

I need more help!
