For 0.17.18 this will just generate a warning instead of crashing the game. Thanks for the report!

Next release will treat empty expression names the same as lack of an entry, meaning 'use the default'. Thanks for the report!

Hmm, sounds like a bug.

For now, try removing the key/value "elevation" pair altogether.

The 'seed1' parameter to the basis noise functions is an 8-bit value. I'm guessing some mod is generating them dynamically or based on noise layer ID and blowing past the 255 limit.

We could just allow larger numbers ignore the upper bits, maybe with a warning. Or provide better error messages.

If I want to have cliffs, but less of them around the start, is there a way to do that? Not from the GUI, but we could just change the 'cliffiness' function to give lower values near starting points. multiply by distance / 1000 or somesuch. (And if we really wanted, that could then be made into an ...

What's the mood like in the office? Do you play any games during breaks? Are you eating pizza? If not pizza, what are you eating? I'm drinking Soylent and have a cat on my lap.

Derp. Integer division of 2 by the number of peaks when calculating peak influence results in 0 when there are more than 2 peaks.

None of the autoplace specifications in vanilla use more than 2 peaks, apparently, which is why this wasn't caught.

Should be fixed for 0.17.9.

Thanks for the report!

The "bug" was that the basis noise function was being applied to integer coordinates, which always returns 0, which isn't actually a bug.

Should be fixed for 0.17.9. Thanks for the report!

Something I've noticed with the map generator in 0.17.6 is the weighting of "Cliff Frequency" below 100% has no noticeable effect on the map generated. Is this just an issue with the map preview, or does the generated map have cliffs present as well? This has been brought up to me on mult...

The peak/dimension-based autoplace specifications being hard to control are the reason probability_expression was added to bypass all of that stuff. max_probability and random_probability_penalty do not have any effect if probability_expression is provided. That is by design. That said, the behavior...

Trying to read the ore_protype.autoplace_specification attributes ( https://lua-api.factorio.com/0.17.3/Concepts.html#AutoplaceSpecification ) at runtime doesn't work. Expected attributes like "placement_density" and "max_probability" are nil. Previously, my mods could access th...

I have found something that does work: { type = "noise-expression", name = "debug-temperature", intended_property = "temperature", expression = noise.define_noise_function( function(x,y,tile,map) return clamp_temperature(x * (1 / 4) * noise.var("control-setting:te...

Having 0.17.6 up and running on my machine now, I'm trying to figure out the right collection of options to reproduce the "3 Islands / PvP Islands" picture. Is that doable with the vanilla interface, or is some modding required? You don't need mods, but you might need to --create a save f...

An updated map-gen-settings.example.json will be included in 0.17.6. For the impatient, { "_terrain_segmentation_comment": "Inverse of map scale", "terrain_segmentation": 1, "_water_comment": [ "Multiplier for water 'coverage' - higher increases the water...

What is going to happen to existing 0.16 maps during the upgrade? Will these keep using the old noise function after upgrade, and generate new chunks which match the old ones, or will there be sudden transitions like we've seen in the past? So TOGoS messaged me the old maps will keep using 0.16 gen...

Create a map without trees I've always wondered, when you do this, how do you get your first power pole? I suspect maybe logs will still be lying around. Though that makes me wonder... with no trees where would they come from? EDIT: No I just tried in and at least in 0.16 there is no wood anywhere....

Could map settings be adjusted during gameplay (like continue playing a map after a update) so you don't have to start over while tweaking your personal flavor? Yep! In 0.17 you'll be able to switch into the editor ("/editor" in the console) and change the surface settings any time. Of co...

Terrain generation updates

Will we still be able to do these things?

1. Create a map without trees
2. Create a map without cliffs
3. Restrict water to the starting area

Mmmmmmyes.
