Biggvs_Richardvs: This looks very much like you don't have the default mod which means you have not used Minetest Game.
Ethereal NG will run on Minetest Game, and I think this is the recommended subgame. It MIGHT run (no guarantees!) on similar subgames (which have been forked from Minetest Game), but it will not run on completely different subgames.

TenPlus1: This thread is in Mod Releases. Please do the following:

- Change thread title to “[Mod] Ethereal NG [1.21] [ethereal]”
- List all dependencies in first post
- Add actual download link containing the mod folder

i read that grass now spreads to adjacent dirt nodes in default minetest, and that dirt with no adjacent grass would stay as it is.
does ethereal use this too? =(^.^)=

Posted: **Wed Aug 03, 2016 08:58**

Ethereal uses the same technique, changing dirt into the grass nearest or green grass by default.

Hi

The mod produces real fantastic landscape, very impressive. But for me there are too less normal biomes like forrests with normal trees or plain graslands.

Is there a possibility to manipulate how much or how often the different biomes are created? Can I delete or disable some of the biomes (like the lava-fields because the cause a lot of "action" when flooding down to the sea).

Thanks, Birgit

BTW: How did you get the big mal, that was shown in the first posting?

Posted: **Sun Oct 02, 2016 08:02**

Biomes are subject to the 'seed' used for the map... Some seeds will produce more grass areas while others glaciers etc.

Posted: **Sun Oct 02, 2016 08:16**

Hmm ... well, yes, I understand that, but as Ethereal is the mapgen mod to create the biomes shouldn't it be possible to manipulate the size and the frequency of a biom?

I had a short look at the file mapgen.lua but I do not really understand it?

Is there a possibility to manipulate the basic mapgen like v5? And if mapgen v5 uses the informations from the mod how does it decide what biom is created?

Posted: **Sun Oct 02, 2016 10:25**

It can be manipulated by changing the heat/humidity values on each of the registered biomes, that way you can make them bigger or smaller.

Posted: **Sun Oct 02, 2016 11:15**

Okay thanks .... I think I found that ... I'll try it to have better results ... or more worse ;-)

I had another question: how did you create the big map at the beginning of this thread? Is it a mod?

Posted: **Sun Oct 02, 2016 14:51**

The 2d map was made with minetest mapper: https://github.com/minetest/minetestmapper

Posted: **Sun Oct 02, 2016 17:26**

Okay ... I'll try to install it ... I wait for my personal guide, my husband.

BTW here is the voronoi diagramm for the Ethereal Mod Biomes. https://www.geogebra.org/m/u2ngcd5F
I'm not sure if I understand it correctly!?

Posted: **Sun Oct 02, 2016 20:08**

When I re-did ethereal biomes I tried to add a more realistic number for heat and humidity to the biomes rather than the spreading out of biomes.

Posted: **Mon Oct 03, 2016 07:20**

Well, but the problem is that the you can see in the Voronoi diagramm for the Mod that there are some Biom types that have a much bigger area and so the probability to have this area is much higher.

At the height of 5 for example you have a big area for Plains and Bamboo.

Or at the height of 0 or 1 a big area for fiery ocean. But isn't it a more strange area that should not be there too much?

I found in another thread the information:

Because heat and humidity are defined as 50 + noisevalue * 50, and noise values vary roughly between -1.5 to +1.5 if they have several octaves, dependant on persistence and number of octaves.
Heat and humidity have 3 octaves with 0.5 persistence, so the maximum amplitude is:
1 + 0.5 + 0.5*0.5 = 1.75 so the variation is from -1.75 to +1.75, but the extreme values are extremely rare, the usual variation is roughly a little larger than -1 to +1.

As I understand this, that means the everything around (50|50) will be choosen more often. But if you choose "normal" values from the earth for the bioms that are around 15°C (?) they will be too far away from the center of the minetest enviroment with an average temperatur of 50 ... lets call it °MT ;-)

If you like I can change my GeoGebra-Drawing to make the points moveable that you can adjust the center-point for the bioms to have the areas in the wanted size. In the existing drawing you need to change the values in the table.

Posted: **Mon Oct 03, 2016 16:53**

> to make the points moveable

This is what i'm doing in GeoGebra with MTGame biomes, moving the points around by mouse in realtime is essential for biomes design. Instructions for how are here https://forum.minetest.net/viewtopic.php?p=230857#p230857

Posted: **Wed Oct 05, 2016 16:27**

I played with the value in the GeoGera file. Make the points moveable is a bit difficult, because the are dependent of the height and therefore I would have to start the file from the beginning. But changing the values in the table isn't difficult and so I have founds values that produced a world with biomes that are ... well .... a bit more realistic. I have more normal grass biomes and less of the strange ones but they still appear. And furthermore the biomes are bigger and so the landscape is a bit more consistent.

Have fun :-)

I created grass for mushroom biome if anybody interest.

Instruction:
1. Add new grass texture files from "textures" directory to Minetest /mods/ethereal/textures/
2. Add source code from .lua files to exiting in Minetest /mods/ethereal/ .lua files with the same name

Posted: **Thu Nov 03, 2016 06:13**

TenPlus1, can i use illumishroom texture with another color in my mod?

Posted: **Thu Nov 03, 2016 07:40**

Amadin: I would prefer it if you would make add-on mods for Ethereal to add new grasses or whatever instead of making changes to the original mod and re-releasing... As for the illumishroom, yes you can re-colour but for a separate mod.

Posted: **Thu Nov 03, 2016 08:44**

I created separate Brewing stand mod with potions, i think use mushroom for base potion, but mushrooms from flowers mod is too easily to find and i not want add ethereal to my mod dependents for one "illumishroom". What you mean "add-on"? Add something in Ethereal by separate mod? For Ethereal i can add many grass for mushroom biome.

Posted: **Thu Nov 03, 2016 09:12**

amadin: yes, a separate mod that adds more things to Ethereal, so your mushroom grass for instance, you could register it in a mod and add decoration which appears only in mushroom biomes.

Posted: **Thu Nov 24, 2016 10:54**

Update:

- Added new Swamp biome.
- Bakedclay plants added to mapgen.

I'm having a problem that was asked efore, but the solutions mentioned didn't seems to work for me.
Mods: Ethereal NG, Technic, Moretrees, MyMonths.
Problem: Rubber trees won't grow
I've tried to grow a rubber tree sapling I got via /give, but the sapling won't grow, any ideas on how to fix it?

Posted: **Fri Dec 23, 2016 09:15**

XtremeHacker: It seems that rubber saplings are coded to grow only on dirt_with_grass which doesn't appear in an Ethereal world, but you can edit the line in the moretrees mod to include ethereal dirt:

https://github.com/minetest-mods/moretr ... s.lua#L139

...change to:

surface = {"default:dirt_with_grass", "ethereal:green_dirt"} -- or even group:soil to grow on ALL soil types.

Posted: **Mon Dec 26, 2016 10:02**

Two questions:

1 - Can this version replace 1.16, or does a new world need to be created?
2 - I noticed a configuration file. Do you have a list (or thread) for configuration options?

-=TommyTreasure=-

Posted: **Mon Dec 26, 2016 17:42**

One of the main updates to NG was the biomes but you shoudl be able to replace 1.16 with it and have things work, some weird biomes may form next to current one's though but nothing too drastic hopefully.
