How can i change height multiplier of the region when importing heightmap?

[Geskawary234]

Rn i am making a procedurally generated world with this extension, I really love it and documentation helped me out a lot, however i cant seem to understand how can i scale height multiplier for individual regions when setting heigtmap to that one region? I am using FastNoiseLite to generate noise image. When i import heightmap to the whole terrain with "import_images()" its alright cuz it have a parameter for height multiplier, but when i set heightmap for individual region, i cant seem to find a function to scale the noise. Is it possible? Or should i some how modify the original heightmap?

Regions store real height. If you have a normalized heightmap, scale and offset it before you store it in the region. You don't need a function, multiply the values when setting the region data per pixel. You can also review the code for import_images.

I am using FastNoiseLite to generate noise image.

Then you should already be pulling data from FNL per pixel to get 32-bit noise, as shown in CodeGenerated.gd. Just multiply and offset it before storing it.

Okay, thank you. I will provide you with what i do

This way it works, but it generates ALL the regions, and i want to make something like minecraft where chunks are generated as player moves. What is the best way to do it? Sorry for maybe a stupid question, but i cant seem to solve it myself.

extends Terrain3D
var RNG : RandomNumberGenerator

var noise : FastNoiseLite
var heightmap : Image
var seed : int
var map_size : int = 1024
var height_multiplier : float = 30

func worldgen():
	noise = FastNoiseLite.new()
	RNG = RandomNumberGenerator.new()
	
	
	RNG.randomize()
	seed = RNG.randi()
	RNG.seed = seed
	
	
	noise.seed = seed
	noise.noise_type = FastNoiseLite.TYPE_PERLIN
	noise.frequency = 0.01
	
	
	heightmap = noise.get_image(map_size,map_size)
	
	data.import_images(
		[heightmap,
		null,
		null],
		-Vector3i(map_size / 2,0,map_size / 2),
		0,
		height_multiplier)
	data.calc_height_range(true)
	data.update_maps(Terrain3DRegion.TYPE_HEIGHT)

I thought you were adding data to regions? That's not in this code at all.
If you're going to use import_images, then just build off of CodeGenerated.gd which I already directed you to.

where chunks are generated as player moves. What is the best way to do it? Sorry for maybe a stupid question, but i cant seem to solve it myself.

You already described how to do it in your first message. But what you described, and your code are two different things. I was expecting to see in your code the creation of a Terrain3DRegion, populating it with data, and loading it into Terrain3DData.

I can't tell you what is best for your game. Your need is the best motivation to learn.

There's a ton of documentation and code for you to read and study to figure out the best way to do what you want. Read the code for import_images.

alright, in any case, thanks for reply, i appreciate your project, gotta be my favourite godot addon.
