Blender: procedural buildings with geometry nodes fields | pt. 1

Hello, here we are again.
This is the updated tutorial for the Blender geometry nodes fields variant.
builder.blender.org/download/...
I used the alpha version of Blender 3.2.0 (95005bbe02cf) for this project
You can get the assets I will use in this build here: kammertone.gumroad.com/l/FieldAssets
Check me out on Patreon: / kammerbild
The full node setup will be released once the entirety of this series has been uploaded.
00:00 rambling
01:00 what you will need to model
03:53 basic setup
09:45 shift the building based on height
11:30 some 'fields' basics
13:20 the switch node
I will upload the next part quite soon. With all the setup there isn't too much happening in this part ^^

[@jeshuagomeznoriega7241]

how do you write ( equal ) in the node id? thanks, incredible video

[@Kammerbild]

Hello, The way I do it (using the searchmenu when i let go of the node connector) only works in newer Blender versions. You can still add the compare node the usual way of course. The important thing is to actually look for a node called 'compare' - not 'equal'. And don't confuse it with a math node. Once you added a compare node there is a dropdownmenu you can set to equal. Hope this helps!

[@jeshuagomeznoriega7241]

@@Kammerbild very helpful thanks, excellent video I love this channel 😋😋

[@NegaBema]

@@Kammerbild I'm running 3.0.1 and there is only a Compare floats node so to make that work is to add a Float to integer node between the compare nodes "Result" output and the switch's "Switch" input. The Compare floats node in 3.0.1. is missing the "integer" option used in this tutorial and it's the only compare node I could find. Nevertheless, works like in this tutorial with the exception that you're working with decimal numbers. I used the default "Round" option found in the Float to integer node. Just thought this might help someone. Thanks for the lesson!

[@Kammerbild]

I will upload the next part asap. With all the setup there ain't too much happening here :D Just have to edit it first.

[@Kammerbild]

Its up btw.

[@PatriceFERLET]

Just one thing. You can drag and drop objects from the object list tree to the node view. That's a bit easier than selecting object info and select objects 😉

Thank you for making an updated version, most tutorial don't take the time to do it and you waste time trying to follow something outdated. So thank you !

[@oneaspiringartist5822]

I made my own version for 3.0 using your last tutorial. A lot of the steps/nodes you showed us were unusable but I was able to make a simple procedural building. Now I'm working on a much more complicated version which is just way too big to even work with unless I group all of the nodes. But the results looks good. Thank you😀

Your first procedural building video introduced me to geometry nodes and trying successfully to rebuild it in blender 3.0 taught me a lot. So I thought: Why not a procedural window for the building and while doing so I learned even more. Thanks for the euler rotation tip. I ran into the same issue with my window and hadn't solved it yet. Finally I know how to fix it. Thanks a lot for your great tutorials. Vielen Dank, mach weiter so. Ich bin gespannt auf den nächsten Teil.

[@ESD8000]

Very, very happy you came back to this tutorial series after the fields rework, especially since the last one must have been a very big time investment to create . Curious what i can guess right for the changing parts this time, thank you for your videos!

[@Kammerbild]

Yeah, there are definetely some changes. A lot of stuff has become a little stiff and complicated twith the fields update - other things are easier now. It will be hard to tell how it will end up, as fields is really quite new still.

[@ZexMaxwell]

​@@Kammerbild then why are you making tutorials now when everything is still up in the air? did you get word from the devs that everything is in final form?

[@ESD8000]

@@ZexMaxwell Fields is the settled on system to go forward with, AFAIK. Blender 3.1 and 3.2 both added ontop of the system, most likely nothing major will change from now aside maybe a more condensed setup in the future with new nodes or some name/category changes for nodes, as he said in the video.

[@Kammerbild]

@@ZexMaxwell Well - by this measure I could never make any tutorial then. Yes - It'll might change... That can happen and it sucks, but that just means I have to update the tutorial. . When I did my original tutorial there was no sign that they would completely change the system the way they did it. So believing that everything will be set and done by the developers does not mean anything. In the case of fields they have clearly said that it is the system they'll go with - so it would be reasonable to assume that while names and minor functions might change the overall workflow will remain the same. I learn something new anytime I do a project - so I don't mind. Keeping things up to date is just part of making KZbin tutorials. If I don't do it, someone else will. And I wanna be the one to do it. I have already done it once and Blender is a lot of fun :)

[@ZexMaxwell]

​@@Kammerbild I'm not saying don't make the tutorial video. what I am saying is to make the video when its not a Alpha build. when you did it the last time, the entire tutorial was pointless since the alpha build didn't have the features that the release candidate had. which makes it really frustrating for a new user to understand the system, when the teacher is using a system that is not the standard. make the video. when the product is done.

[@bearbones7913]

Hi so i'm on the basic setup chapter and theres a hiccup with the placeholder cubes. When i use obj info the geo node cube is separated into several different cubes and when i try and correct the measurements so that they appear to be combined but when i increase the width the cubes overlap. Have i missed a step?

Thanks. Do you have an introductory tutorial on geometry nodes?

[@michaelwilliams5719]

Could you do a tutorial on modeling the pieces?

[@justpoppinthings]

I need you in my life

[@bobbyrichmond6691]

anyway to correct this if the modeling is not perfect 1x1x1 m scaling? mine seem to clip together, or be very far spread. I had been following the video in sequence so I modeled my middle floor, middle corner etc. first. and was wondering why when adding more width that I was clipping the mesh into each other. after a few hours or testing I found the problem being that it was doing so because it wasnt a 1m x1m x1m. any way this works for any scale geometry?

[@cornelius-harlem-alston-co562]

I applied a custom material to the object im using to create one of my wall modules, any idea why once the nodes generate the building, the textures arent visible?

[@indrakomara6966]

thank you...

[@TheJovialBrit]

@Kammerbild - I am thinking of becoming a Patreon. I also purchased this from your Gumroad but it says that it's now redundant... Can I ask you something? If I model the interiors of each part will that work or will it just mess it up? So, for example, if I model the parts to not just be exteriors but also have the associated interiors - would that work?

[@d1mling]

[@rafvanraevels]

Strange my 0 point is on the front right of the 3D cursor while yours is in the back left?

[@darkobakula5190]

I don't get how you would use an ID node to select sides of a cube or some other mesh unless the mesh was generated using GeoNodes and I would assume GeoNodes assing ID in some order from -X to X+, then iterate Y value and then Z.... basically some sort of nested loop to give good IDs to a mesh. And even then, you would need either complex logic node setup or a Node to output Arithmetic Sequences to get sides of a mesh. Good thing they have selections based on Normals of a mesh.

[@SnailSpaceWTF]

How much would this need to change if I knew my modules were 3.25m?

[@PolygonPapi]

Hello! For some reason I cannot get the basic cube to work, in terms of the proper size. Tried scaling down to 0.5, applied scale, etc. Still not matching. Any ideas?

[@LoudNoob]

Ohhh, yay

[@lucasfmfeit]

I am at 11:20 and my cube is worng =/ Can´t seem to make it right so that the faces have the same dimensions, it looks like they are one over the other

[@Ilumzar]

Thanks, very nice and on point tutorial. However one minor critique on your vocabulary, that unfortunately a lot of artists get wrong. the word 'vertice' doesn't exist. it's either vertices (plural) or vertex (singular)

[@scottsturdevant8400]

Yesssssss

[@mehimanshusaini]

[@deanjohnson7973]

what dimensions were your modular pieces, I assume 1m x 1m? apologies if you mentioned it in the video

[@Kammerbild]

Yes, they are 1mx1mx1m. That is making math easier. You can scale up the building to realistic proportions at the end using nodes when everything is done.

14:32 - Nooooooooooooo!!!!!!! 😭 You're aus Hamburg!!!!!!! We got _one_ word right in English! You get to say Euler, in its pure deutchen Form!!

We have so many exceptions in English, you cannot be blamed. 😉)

[@abedabusalha]

Can I follow this on 4.0????

[@angryangrystudi6818]

may I know why I can't drag compare node (like 12:06)??

[@Kammerbild]

Perhaps your Blender version does not have it yet. I don't know if it is in the most recent stable build, but if you download an experimental version this feature should be there ;)

[@DarkAutumn3D]

Why does it have to follow 1mx1m? I mean the average height of a room is at least 4m so how can this possible translate into a games engine? Can't I just use 3mx3m?

[@Kammerbild]

We use 1x1x1m to simplyfy the math. We will do a lot of calculation that gets needlessly complicated because we'd need to drop in additional nodes to Account for the bigger Size. Don't worry though. We will scale up the entire building in the last part to reflect a more realistic size. It's just simpler to Account for it once at the end instead of throughout the process.

can i make it if it's more or less than 1meter by 1 meter cuz that' s my problem

[@Kammerbild]

I wouldn't recommend using a different scale than 1x1x1m - it really complicates all math. It's possible, but provides no benefit. You can scale the entire building up in the end to get realistic proportions as I show in a later stage of the series.

I really love your tutoring style, explaining what and why we did it. But you are a little bit to fast for me. I have to go back and forwards on the video, which is a little bit annoying... but otherwise, great content!!!!

[@filamentio]

I would love to do that but I have two problems: 1) For a reason I don't know, 2 Cubes are always drawn for the width, even though I enter 1. Height and length work. 2) I have a bigger problem with the rotation. It seems that the compare nodes have been removed or changed. The only thing I can find is "Compare Floats" but I can't do it with that either. I have already discovered an explanation in the comments, but to be honest I do not understand this explanation at all :C Maybe someone can help an incompetent idiot like me? PS otherwise great video PPS: German?

[@Kammerbild]

Nabend Johannes, 1) A cube always has 8 vertices - otherwise it wouldn't be a cube of course... So even a cube with 0 subdivisions will always have neighbouring vertices. So I don't even know why your height and length can be turned down to 1 Element - theoretically that shouldn't be possible. In order to have a 1x1x1 building, the source can't be a cube, but only a singular vertex. 2) I can't affirm that. I have just downloaded both the most recent experimental release and the most recent stable release, and both have the compare node in them. Maybe see if you have an outdated blender version.
