[SOLVED] Shader chunks - Shadertoy internal updates

[Thomas_Due_Nielsen]

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

please help - the examples refer to these links:

Shadertoy to PlayCanvas: River

Hi, Shadertoy to PlayCanvas: Shader - Shadertoy BETA Project: https://playcanvas.com/project/677852/overview/a-river--by-raymarching Build: A River - by raymarching - PLAYCANVAS Feel free to fork. Regards, Saad

• and though externally to
  Shadertoy to PlayCanvas: Sirenian Dawn | Playing in Canvas
  (al though the last one being more external, one can imagine that you/Leonidas wants the website examples to work etc )

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:
