Loving the first three ideas there they could be fantastic use cases and lightweight!

Single biome masks sounds fantastic too! I can already see the drop down menu haha.

Enjoy your coffee, a tea for me soon

• Fake “tectonics” to create procedural but cohesive landmass and mountain range shapes
• Rain shadow/Rainfall prediction
• Biome prediction (based on rainfall, proximity to major rivers etc)
• Population density prediction
• A single node for multiple biome masks (e.g. from koppen climate classification)

I’m sure I’ll think of more once I’ve had a coffee!

You’ll want to do that first and any subsequent masks/colour drag and drop a wire onto the node, you’ll get a context menu to add it to the unreal node

Hope that helps

So long story short, Im trying to set everything up for export to unreal and this is the first time using the Gaea2unreal plugin. Everytime I try exporting my final color mask using the unreal node either it goes geometry chaos when choosing default or height field, or it gets completely grayed out when I use mask. How to solve this please?

I’m really glad by how the erosion and flow maps translate into stylized shapes with some simple trick, you can even use the colors to make really good stylized effect and more.

Well said Ty!
I still do this to visualize scale better, Custom scaled shape that you can bomb on top of the terrain to get a sense of scale. This here is a 30m wide and 10m tall cylinder. Human scale would be too small, but you can import familiar shapes or use basic shapes at different scales 10m, 50m, 100m for visualization. Height is easy as you can autolevel + clamp to input precise values but for width, I first used overlay + grid to roughly get the scale I want.

Thank you for your reply. Your method is excellent and very helpful. Creating a custom macro might simplify things, but it still requires calibration for different terrain sizes. I’d like a reference point with absolute height values ​​that can accurately display a scale close to reality regardless of terrain size, thus optimizing this reference process. Currently, the software uses meters, and calculating scaling values ​​confirms the map scale. However, I’d appreciate a more efficient way to accomplish this.

I create rather complicated node graphs, and I’d have to revisit/improve them because to someone who’s learning and didn’t create them it probably looks like a confusing mess haha.

The idea of more examples etc. has been discussed. might take some time to refine a few terrains into simpler versions for more examples.

Regarding this it’s mostly just a time management thing. I am 1 person. I need to research ways to create terrains, then record edit and upload tutorials, test SEO stuff, record, edit, upload documentation videos, create art for thumbnails, blogs, covers. So it will likely happen in the future when time allows for it. But for now documentation and content are the priorities.

To help maximise some usage If you’re learning I highly recommend further exploration based on it, think of it as lego just using blockas and filling your imagination and leveling you up too

Here i took all the keywords and references mentioned and spent 10/15mins coming up with my own idea from it for the terrain shape.

Hope that helps some

or the file nodes?

• In both cases one answer is the file node, it’s not licensed to just share ( megascans asset) you can just replace this with anything mind, or get the megascans asset, but if it were shipped without the file or a different one, then someone follwoing step by step woudl still be confused and just not understand.

• Another could be for tutorials like this ( step mby step) some of the goals are to make a users step by step themselves to understand why and apply the ideas themselves ( a learning process)

• Finally it may be something the team want to refine to add to the examples

There could be even more reasons but these are a few logical ones.

[!note]
Here is the Original File Node input

In cases where Maarten has shared files and deep learning.

Check out out his post here and his latest starter guide on YT

Hope that helps

To the Gaea team. I came across a tutorial you published and I am wondering why you don’t share the file associated with your tutorials so we can follow what happening and become better using the software ? is the file a secret?

Cheer

Your best best is what Klaus has said.

However just to help you both further understand contcepts:

Terrain Scale + Human Scale

To give you some perspecitive the video i have here is a human scale or 160cm tall and 1m wide in the default terrain scale as you can imagine, you just cant see it.

Hill Scale + Human Scale

If you scale the terrain def down to 100x100m you can also add a 2x2m cube and the same 1.6m height which could represent a hill fairly well.

[!Tip]
If you are using terrain def relative scales, many nodes support metre values inputs as well as decimal or percentage

It is time to switch career to a poet.

This all started because I am making a Valheim map and decided I wanted to full send learning this program so I could make it epic but also remake some of my older maps with those skills as well.

The terrains require you to draw a valley, and for the heavy file please bake the first half of the shaping once you get it to a place you like!

Thanks for replying, Sorry I didn’t see your message until now, It’s been a busy day.

Here is a screen recording I made showing how I imported the tiles into blender (the way I have been taught is best) https://www.youtube.com/watch?v=RQI4Aj3e9II

I will note that the few times I was clicking around randomly and blender did nothing, I was loading in the 25% overlap exr files (that window was showing some private details so it was hidden).

If you would like the files from my orgional post you can get them here (Password: Gaea, link expires 1st of April)

But yes, I will check this out in the morning just in case I have missed something on my end.
I can’t imagine auto leveled anything there mind.

I will update them here for latest versions

And let you know if I find anything different as well.

I am not really a blender user, mind giving me a quick step-by getting to the point you have the issue?

In several of the tests that I have done for this issue I have made sure to do the “Bake required nodes” each time and that has made no difference. Here is what the file looks like (I belive it’s the file you provided on discord a while back)

When you set up a node for export by default, you mark all of its output ports ( right side ports on nodes)

So in your Heigh Map named node it has the output ports

• Out
• Layers

it’ll build 4 tiles for each.

That’s confirmed on your screenshot.

You can configure what output ports you want to build and export in the 'lil configure icon left of each node name there.

[!TIP]
You can quickly mark just the main out by selecting Primary Only on nodes with lots of output ports.

Hope that helps!

No promises but don’t want to leave you hanging.

In the build folder, I find four slope maps, four tree mask maps and eight 8k height maps ( 4 “Map_layers” and 4 "Map_out) all different ?!?

Close enough I think, Mods can move the topic if it needs more clarity or exposure

Mods have these shields if you need to identify quickly

I’ve already started working through the resources available, especially YouTube videos, but I learn best when I can ask questions and get guidance tailored to the specific workflows I’m trying to build. I’m looking for a way to accelerate the learning process and build a solid foundation with help from someone more experienced.
