Looks like some internal updates* within Shadertoy is messing up the (otherwise useful) examples:
https://playcanvas.com/editor/scene/1548486
https://playcanvas.com/editor/scene/1548557

• both project’s backgrounds/shaders fail

*) or wherever the dependent libraries lay - Chrome or likewise

Hi @Thomas_Due_Nielsen,

The shader chunks API is still unofficial so it’s expected to break from time to time, especially for older shaders.

You can check the following shader migration guide to learn how to update these effects to work with the latest engine version:
