what's stopping me from doing more stuff with geometry nodes is that I haven't found a tutorial that explains the logic of the nodes in a way that prepares me to play around with them confidently, it's always tutorials of doing something specific with them and when I try to make something different I feel like I haven't learned as much because I fundamentally don't understand them yet

2:48 "You can take very simple inputs" - shows the absolute big ass chungus tree

This convinced me to learn geometry nodes asap. Fantastic tool for gamedev.

I hope this also eases people into programming, both within Blender and outside of it. Like programming, there is math involved, but us creators don't need to actually solve the problems - we are just giving it the equation/how to solve it. Artists can really benefit understanding these concepts and how to utilize for their workflows.

"From a very simple input"- proceeds to connect 50 different modifiers in chain for a couple of blocks to move along a curve :D

Jokes aside, this has been a very intuitive explanation! Thanks :)

I’m very new to Blender and 3D, but it’s still evident to me just how powerful geometry nodes are. An enlightening moment for me was trying to figure out how to do something that seems very simple: take a mesh, repeat it evenly around a circle, and animate both that circle of meshes rotating/expanding and also animate each instance of the mesh rotating around its own geometric center along the axis tangent to the circle at that point. I’m certain an experienced Blender user could easily make that happen with a modifier-based workflow, but it wasn’t at all obvious to me how to go from either an array with object offset or an array constrained to a curve plus a curve modifier to what I wanted without either deforming the original mesh or having to do a lot of manual duplication. With geometry nodes, this was as easy as using instance on points over a circle, aligning each object to the normal of that circle, and then putting a transform node between the geometry input and and the instance input of the instance on points node to do the local rotation. With that all set up it was as easy as keyframing every slider I wanted to animate. If it’s that easy for me to see the possibilities, I can’t imagine how powerful this system could be in the hands of someone with real experience.

Buying this course. Love how this was explained.

Fantastic overview. I've only recently starting using geometry nodes and they've been an incredible tool. Thanks so much for the continious development of this incredible free tool!

It really dose feel like an achievement when you put something together with geometry nodes and have full controller over your models.

This is like that first lecture in class that gets you really excited for the material to come. I am definitely going to have fun with this.
