Having fun diving into UE Control Rig lately.

Epic’s new resources pushed me to explore more, especially physics and runtime animation.

I’ve also written a brief document explaining the PCG graphs

Finished my GPU-driven PCG mandala generator in UE.
The tool builds patterns using two approaches:
UV-Based: converts UV space into polar coordinates and samples patterns.
Point-Based: generates target points directly in polar space and uses them to copy and place patterns.

Generating mandala patterns is my next PCG experiment.
A custom HLSL node converts UVs to polar space and samples the texture.
Each pattern can also be masked using RGBA and used to scatter different static meshes based on those masks.
Still WIP, but getting close!

Stylized Rocks A group of stylized rocks for you to use as you prefer.

Started a new challenge in my free time, a kind of devlog journey around this spider mech character.

First step, walking procedurally! It can adapt its steps, and with custom gravity, it now sticks to surfaces and walks across any angle, even rocky, uneven ones.

Nanite Assemblies in UE5.7 let you reference thousands of meshes in a single Nanite StaticMesh.
I think it unlocks a new level of procedural content generation.
In this test, ~5,000 meshes became one asset, small file size, great performance!

I wrote a brief document about the tool, which you can find here:

I hope it’s useful for anyone exploring procedural workflows in Unreal Engine!

This is just a simple test, nothing advanced, more of a first look to understand how it works. I’ve shared the project on GitHub in case anyone else wants to try it out or build on it.

I’ve been playing around with the new GPU Texture node in Unreal Engine’s PCG system. It lets you sample texture data on the GPU. Super handy and full of potential!

I first calculated the edge of the previous book.
Then used a sphere-line intersection algorithm to find a hit point.
Finally, I measured the angle between the initial upright state and that hit point.
The final transform applies a rotation around a dynamic pivot point based on the lean direction.

Procedurally generating a row of books in Unreal Engine using PCG is fairly straightforward, but handling gaps and calculating lean angles was a fun challenge I explored in my free time.

New update of my StatWatch plugin!

Updates:
- ShowFlag commands to toggle the visibility of specific rendering features
- Custom input commands for fine-tuning engine settings
- Color-coded buttons for better usability

Still a work in progress but getting closer to something solid!

New update on my WIP Ivy Generator

Using Geometry Scripting in Unreal, I saved branch length and spawn time into a new UV channel during StaticMesh export.
Then used that data in a custom shader to animate ivy growth over time.

StatWatch is a Centralized Command Hub for Performance Analysis.
So far, I've built a library of commonly used STATs, but I already have more ideas in the pipeline.
It's fully data-driven, so users can easily add, manage, or categorize commands without touching the code or blueprint.

#UE5 #Tech-Art

Added some new features to my UE Ivy Generator:
Sub-branch generation for more natural growth
Size filtering to remove short branches
Merge & export to save ivy as a new static mesh

Still a work in progress, but getting closer!

Modeling organic branching structures with the space colonization algorithm and JavaScript Learn how you can procedurally generate realistic branches, vines, veins, roots, and other branching structures from nature using codel

Some resources that helped me along the way:

Implementing the Space Colonization Algorithm in Unreal Engine PCG has been an exciting challenge to tackle in my free time.
PCG generates the branch points, which are then sent to a blueprint to create branch meshes using spline mesh.
