Blender Geometry nodes - Procedural scales with flow control

In this video I'm showing how to procedurally create scales on an object with geometry nodes and use a hair system to help controlling there orientation.

This is the most outstanding tutorial, and it has low views? I can't believe it. Mate, this is an amazing solution!

Thanks mate, really appreciate it

Right what I needed for a completely different purpose though but that’s the beauty of geonodes

The Mesh to Points node can be set to Faces instead of Vertices. This places a point at the center of each face. Blender also does this faster internally than manipulating the original mesh.

Great tutorial, thank you! How to make them appear in certain places only, like using vertex weights?

@stefanmayr1983 4 ай бұрын

yeah, with vertex groups or even textures you could give a density mask

just perfect it would be great to add a fonction to scale also the scales with the length of the hair guide.

Hello, i had this initially in there. However there is no smooth length brush for the hair system, so i rather opted to do it with a texture instead

Is it possible to export the spikes and the object for 3D printing? From what ive tried I havent been able to export it.

@tomhoefken6675 3 ай бұрын

NVM, u can export as an OBJ into whatever program, then export that into an STL.

Will these move with the object when I pose it, or will I constantly have to align it to the pose?

@stefanmayr1983 Ай бұрын

They should move with your object. Maybe some need for adjustment here and there

I keep running into an issue... every time i try to scale for the first time, my scales look nothing like yours and i don't really know why... :/

@Frigus3D-Art 11 ай бұрын

Hmmm mb try click the sphere -> ctrl+A -> apply scale This would be the first what comes into my mind, but i would need more information on whats not working

@raedinsmore7732 10 ай бұрын

Did you double check your origin? And make sure to apply the scales and rotations to the scale instance? That was what was causing me a few issues.

@davidgeuens5236 4 ай бұрын

great tutorial! however I'm having some trouble, does anyone else have an issue with the rotation of the scales, it seems like mine can only take two positions, so when I comb my hair curves, nothing happens until I reach a certain treshold, than my scales affected by the hair snap a 180 degrees... Does anyone know where I made a mistake by any chance?

@stefanmayr1983 4 ай бұрын

Hello, and thank you very much. It's rather hard to pin point the issue without seeing the file. Rotations are a fiddly topic since they depend on axis order, radians vs degrees, vector vs rotation etc. i often don't know what I'm doing, but after a bit trial and error, i often get to the "Heureka moment". Sorry for that vague reply

@@stefanmayr1983 thanks ! of course I understand you can't help me without seing my nodes, I will continue to dig in my nodes and I'm sure I will end up finding the reason. thanks for the tutorials !

It happens with me in a similar way. When combing the guide curves, the scales rotate about one axis (normal vector), not two! As far as i understands, the author everything happens in a similar way. He sets the coordinate axes in the nodes so that the scales are more or less laid out, and then corrects their direction by combing. @stefanmayr1983 If I'm wrong, please correct me
