Hi, I’m working on a series of small material experiments using the Absolute World Position node in the materials editor.
The focus is on exploring the different kinds of effects that can be created through world space position data in the material graph. The experiments are all part of a single project on Github. Dropping the link below if anyone wants to dig into the node graphs:
Will be adding more as I go along with documentation covering the workflow. Happy to discuss any of the setups if something looks interesting.
First experiment is a Scan Pulse effect, a sweeping world scanner effect that propagates outward from a trigger point and lights up geometry as it passes through the scene.
I tried two different approaches to build it, both as post process materials using the Absolute World Position node. The first uses basic math nodes to compute distance from the pulse origin and derive a ring mask from it. The second replaces that distance logic with a Sphere Mask node and runs the result through a Sine to produce the ring pattern.
Sharing the workflow here for both implementations:
Added two more material experiments to the project.
The next one is a Shockwave Pulse effect, a ring that expands outwards across a plane from a trigger point.
Following that is a Ripple Effect, a continuously expanding set of concentric rings that radiate outward from the center of a plane, with the rings fading out towards the edges.
