Procedural Grease Pencil Animation with Geometry Nodes in Blender 4.3

A step by step tutorial that shows you how to created a soaring and satisfying geometry node simulation with Grease Pencil geometry in Blender 4.3. New to nodes but handy with a Grease Pencil? Well this might be the video you've been waiting for.

The way you explain complicated stuff about blender is awesome. I truly enjoy the whole vibe around it as well. Clean, clear voice, no useless extra stuff. Great great work, truly!

[RTKdarling]

Your ability to use blender to EXPLAIN blender to me is unparalleled, and it feels like you've gone a bit deeper here. That just means I'll have to watch it twice

The quality of these videos is INSANE! I want a tutorial on how you make these tutorials! This level of detail and the animations are incredible! the dad jokes arent to bad either. Thank you so much for these videos these are my favorite thing on youtube! you are amazing! and thanks for making the videos so accessable those of us who are blenderly challanged are very appreciative of the thought!

Really very interesting and informative, thank you!!!! As the Geometry Node approach is relatively new to me, I had a bit of trouble understanding everything on first viewing. But when I saw the video again, translated into ancient Greek and in reverse, everything became clearer.

[Kram]

the production value of your videos is utterly bonkers - how long does it take to edit a video like this?

[laemon]

your visualizations are the next level of educational content, I am sincerely glad that content of such a high level appears these days. Thank you very much!

Being into computer graphics since the 1980s I've always been afraid of vectors because despite using them lots all the time, I never fully understood what they are and how exactly they work.
That changed in a matter of seconds after you started explaining them and it seems so stupidly simple now! Words can't describe how thankful I am for that!

Fun tip for those who make this:
the *Roughness* on the noise texture, increases twitching motions.
Setting the Multiply node designated for, "Speed, " into a negative (like -2), makes the lines seem to crawl away.
Getting some really satisfying squirmy-worm and scattering-bug like animations by tweaking these two values.

A new Harry Blends video, suddenly it's a good day.

Both simulation zone and repeat zone allows you to pass attributes directly into the unnamed node slot on the entry and exit nodes. You do not need to use store named attribute

[ZeroDean]

Your videos are just... Amazing. Man, I love everything about these.

This is awesome Harry! I've finally committed to diving into Blender nodes and this video is coming out at the perfect time to bolster my learning. All the props for a video somehow turns boxes and noodles into an engaging and entertaining time!

Something that I was a bit caught up about was the control point indeces. You mention they help to know "who is who" but don't exactly mention HOW they are ordered (in a certain direction along the spline based on the grease pencil stroke and what order they were drawn?)

Explaining this might have also made the concept of repeating for every index to drag the "previous" point along make a bit more sense, because otherwise it just makes it seem like you are iterating over this large number and then magically the splines stay connected. Just a quck mention of how grease pencil is stored would help clear up the flipping of the tangent attributes as well.

Still amazing stuff, Derek was such a lovely surprise I need more of him.

You are chronically undersubscribed to mate... the video quality is just amazing!

[joshuab]

I truly truly love your videos! I always learn so much and they are immensely entertaining. Well done good sir and thank you!

[Thiagz]

You are a Genius! And you take your Time! Thank you so much

[lutzilutz]

Please Jack, we need to go back !
(Nice video btw)

[hyruleorchestra]

This is so next level! Thx so much mate! I can't even fathom how your brain comes up with those solutions. Really impressive.

Please, if possible. Can you explain how you make those node tree animations and what tools you use for that? It's so unique how the nodes slide into place.

I definitely don't wanna copy your style, just wanna learn, how this can be achieved.

[AntoCharles]

banger good shit -- I have so much respect for the editing it must of taken for the clean video and concise explanations

[chluaid]

Harry was very tired, so for those who had a stroke reading the description, allow me: "A step by step tutorial that shows you how to create a soaring and satisfying geometry node simulation with Grease Pencil geometry in Blender 4.3..."

I usualy watch the first half of your videos coz i am interested in and i am following along in my mind…than i always get lost somewhere on the way but i will still listening to the end coz of your humor 😊

But in this case i will probanly rebuilt it coz i have some usecases in my mind. to bad i will never understand what i am realy building :)
But if it works, it works!

Thanks
