DIY Rendering Engine Like It’s 1975

What do you do when you need fast info passes rendered out but are too stupid to set up something in ROPs and too lazy to use Solaris? Right – you build yourself a 1970s render engine straight in SOPs. Clever? Not sure. Useful? Definitely. […]

Geometry Nodes Simulation: Relax Points

Often you’ll need point distributions with non-overlapping points. Be it that you want to pack scales onto the surface of a fish or distribute vegetation on your procedural terrain. Although the “distribute points on faces” node comes with a poisson disc mode to remove overlapping […]

Geometry Nodes Simulation: Advect by Curl Noise

Simulation inside of Geometry Nodes is finally possible with this “buffer” hack. After setting up the sim environment, Manuel explains to you what the curl of a vector field is all about and implements a version of curl noise to drive some simulated particles. Download […]

Connect The Dots with Geometry Nodes, The “Plexus” Effect

This time we’ll create the “plexus” effect with Geometry Nodes inside of Blender. Manuel shows you how to abuse geometry to fake a loop, that tests all connections between the points of an incoming point cloud and compares their lengths. Then, only the ones are […]

Geometry Nodes Ep02 – Working with Geometry

Now it’s time to get our hands dirty with Geometry Nodes. Let’s create our first procedural setup, that turns a triangulated model into an alien mesh structure. In this lesson you’ll learn how to use Geometry nodes to modify existing geometry and how to branch […]

Geometry Nodes Ep01 – Intro to Geometry Nodes

In this episode we’ll look into how geometry is stored inside of Blender, how polygons define the connectivity of vertices and how Geometry Nodes is just another modifier, but one that can be customized without limits. To follow the lessons you’ll need at least Blender […]

Geometry Nodes Ep00 – Overview

Blender rencently added a brand new procedural system to its feature set: Geometry Nodes. While being quite powerful it’s not necessarily easily accessible, especially if you are new to procedural workflows. So we decided to cover this system in depth with a new patreon course. […]

Geometry Nodes 3.0 – Cube Grid with Fields

The Geometry Nodes Team decided to redo the architecture of Geometry Nodes for the Blender 3.0 release. Fortunately we can have a look at the new way of working immediately by using the 3.0 Alpha. This tutorial creates a similar effect as my older Cube […]

No VEX Houdini: Organic Modelling Using Winding Numbers

Continuing our “No VEX Houdini” tutorials, Mo covers implementing a very clever technique to model organic surfaces using a mesh’s winding number, as presented in this thread on Twitter by Daniel Piker. In this quick (sub 10 min) tutorial, Mo will use one of Houdini’s […]

Nerd Rant 2.0 – Ep.1: Blender Geometry Nodes

Yes we still have some black frames in there, yes the audio is still slightly offset, no we don’t have a proper intro yet… but… you get the idea. In our second (or first depending on how you count) episode of our new nerd rants, […]

Cube Grid – Use Color on Geometry Nodes Instances

Geometry Nodes inside of Blender is constantly updated and expanded on. Using the latest Blender 3.0 Alpha we can now transfer color to geometry generated through instances. This wasn’t possible before and opens a wide range of possibilities for creative expression in Blender. Follow Manuel […]

Guest Tutorial – Jeroen Claus: Origami Bunny

Super happy to have Phospho’s Jeroen Claus back to present one of his production setups, this time covering how to turn any geometry into an origami version of itself, inspired by the amazing work of Robby Kraft. Project Assets Download Project File

Keycap Sculptures (Disco Ball Tiling)

When we received an E-Mail by Eduard, asking if we had any idea about disco ball packing, we were intrigued. Eduard pointed out that his (apparently very patient) wife manually tiled this sculpture and was wondering if there’s any way to automate it. He also […]

Bubbles Yet Again: Implementing Glassner’s Bubble Triplets in VEX

Bubbles. Again. How thrilling. Wait – before you leave hear me out: Building this setup was one major step for me towards becoming brave enough to tackle implementing my first computer graphics paper. Andrew Glassner wrote a fantastic article about how soap bubble triplets form […]

Sloppy Unreal 03: Correcting Mistakes & Bevelling Legos

EDIT: Damn it, I think specular in UE and me are cursed. When I was testing this setup I had post processing exposure cranked up, which messed up my results. Turns out that specular expects a value between 0 and 1 which internally is remapped […]

Guest Tutorial: Path Solver

We’re thrilled to have Houdini artist supreme Vladyslav Lavrenov for a guest tutorial. And quite a hefty one! Vlad takes us through his reasoning and steps to build a path solver in Houdini to have seemingly random momevements on a grid form a coherent behaviour. […]

Houdini 17 Quicktip: Packing Geometry Using the UV-Layout SOP

With the Houdini 17 party still going, let’s have a look at a somewhat hidden gem in H17’s tools: The UV-Layout SOP. “Wait! I don’t care about ’em UVs!” you might say. We hear you, but they are not really the focus of this tutorial. […]

Knitting in 3D – Building a UV deformer

Knitting in 3D is quite popular these days. Although it is not too hard to achieve, building a knitting setup presents some challenges to the TD. In this tutorial Manuel shows you one way of modeling a knitted 3D object and a method of making […]

Differential Mesh Growth

As some of you already found out, it is quite possible to set up differential growth not only on a line but also on a mesh. This tutorial goes into the details of doing exactly that while allowing for some degree of art-directability (is that […]
