Some of you fine folks asked for a tutorial on this blender work flow. (Which I haven't done, sorry)
But I'm considering to offer the blender file for download if there is interest. I just have to clean it up first.
Please let me know if that's something of value to you (before I waste my energy putting that together 😝)
Over the last 5 years, I’ve been figuring out how to make urban & cyberpunk environments using Blender.
Here are 3 of the most important things I’ve learned to make crazy neon filled scenes like this:
This was blender 3.3.2. For 4.2+ I use these settings:
Sampling:
Viewport → Samples: 64
Shadows →Steps: 16
Raytracing:
Method: Screen - Trace
Resolution: 1:1
Max Roughness 1
Raytracing → Denoising
Raytracing → Fast GI Approximation
Method: Global Illumination
Raytracing → Fast GI Approximation
Resolution 1:1
Rays: 4
Steps: 32
Precision: 1
Performance
Enable High Quality Normals
Viewport → Pixel Size: 1x
Colour Management
View Transform: AgX
Look: Medium High Contrast
Exposure: 1.5
Learn how to create procedural trailing light effects inspired by the PS5 Pro presentation—no keyframes, just Geometry Nodes.
Here’s how it works:
1️⃣ Start with curves: Define the shape using procedural values for easy adjustments.
2️⃣ Refine the details: Smooth the curve with Fillet Curve and Resample Curve nodes.
3️⃣ Stack the curves: Use Instance on Points to stack curves along the Z-axis, adding randomization and spacing with Merge by Distance.
4️⃣ Transform curves into cylinders: Combine Curve to Mesh and Curve Circle for clean light trails.
5️⃣ Bring it to life with materials: Animated wave textures and randomized emissions create the glowing effect.
One challenge was making the wave texture follow the curve path.
Solution: Use Spline Parameter + Store Named Attribute to drive the texture vector.
For animation, the #frame driver creates constant, adjustable speed variations.
