Blender Geometry Nodes Are Awesome! And Now... Easy to Learn!

In this tutorial we show how easy (and powerful) Geometry Nodes in Blender (3) can be by creating a very simple Voxel tool. We also go quickly over what geometry nodes are, and show you how to enable depricated geometry nodes if you want to follow along to an existing but outdated tutorial.

There is a complete step by step text version linked below.

Catching up with Houdini now. I had been trying to follow tutorials on this, but the nodes were missing and i knew nothing about them being deprecated. Thank you for this, now i can go back and follow along and master geo nodes. Salute to you!

Cool demonstration! Though technically this is not voxelization. Voxelizing would be to sample the mesh uniformly while selectively filling a uniform 3D grid based on that.

Thank you so much this is exactly what I was looking for to get started with geometry nodes!

[Victimxofxprogress]

You have a very interesting definition of "Easy to Learn"

I'm sorry about my English. Thank you, Thank you, Thank you! I just followed the text. Great! (From Brazil)

That geometry nodes thing is interesting. Good demonstration.

This isn't how voxels work. You just scattered cubes on another geometry.

Mike is so much happier talking about Blender stuff than stuff like Lumberyard

I loved this! Geometry Nodes are getting further and further :D

[AndrewBrownK]

Love this. Would be good for scales on a creature e.g. snake or dragon

How does one take the node setups to something like Unity for instance.. always wondering that
Same for node based shaders that look great in blender..how would one use those in unity without rewriting it all over?

[summerWTFE]

What I’d like to have.
1. Import to game engines where I can programmatically set the node values. And distribute the engine with the game. Both things Houdini can’t.
2. Use one geometry node instance as input in another. I.e. make a concrete block node and use that in a wall node. Can be done in Houdini but is incredibly cumbersome.

I made a render of that hex map thing that I've been using as a wallpaper
the dude who made it is really good

[somedude]

What does this have to do with voxels?

[SYBIOTE]

is it possible to export the logic with the nodes to other game engines?

[wendten]

pixels dont overlap neither does voxels. You should be able to get around this using a round function on each produced vertex, and the a weld modifier to the end product.. anyhow great intro

[Ddos]

So it will be a free alternative to houdini too ?

What's ironic about this video is that I was actually needing a voxelize tutorial for a project of mine. Thanks.

Anybody know if they fixed UV outputs for the geometry nodes in 3.0? in 2.9x the node network deletes all uvs of meshes used as input, making it useless to distribute uv mapped meshes - which kind of makes the nodes very very limited in their use for game development. Lets say you want to make a bush out of planes or a roof out of shingles where you only made like three... won't work in 2.9x because there won't be any uvs. Well it works if you use certain artstyles but you know what I mean!

[jendabekCZ]

They will be awesome for game-development when it can prevent UVs and other mesh data ... I am pretty sure the author of the video didn't even try to use them for any real project, like in case of 99% tutorials demonstrating scattering on 10x10 meter "scenery".
