Works in Divi without touching code
Every download includes a ready-made Divi 5 section for each shader (packs also include one file with all five). Import it, change the words, save. Hand the page to a client and they edit it like any other section, while the shader keeps running behind it.
01
Import
In the Visual Builder, open Portability, choose Import and pick the .divi.json file.
02
Edit
Heading, text and button are normal Divi modules. Set height in Design > Spacing or Sizing.
03
Publish
Save. The animated background shows on the live page and in preview.
// Plan B Code module fallback. If the import doesn't work on your Divi version, paste code-module/<shader>.html into a Code module at the top of any section. Needs an Administrator account so WordPress keeps the script.
// Not on Divi? HTML drop-in. Upload one .js file, add <div class="shader-bg" data-shader="…"> and the background mounts behind its content. Works on any HTML site.
// 02 Overview
What it does
A slow sideways drift through falling ash and rising embers over a burning horizon and ruined skyline, with heat haze, out-of-focus bokeh and one pulsing chartreuse warning lamp on a radio mast.
Part of Shader Pack 4: Cinematic.
What’s included
- Original standalone HTML page (
04-ash-and-embers.html) - HTML drop-in: one JavaScript file, a copy-paste snippet and a demo page
- Divi 5 section (JSON import via Portability) plus a manual Code module fallback
- README files with install steps and settings
- LICENSE.txt (Schimke Studios Shader License)
Formats
HTML: a JavaScript file that mounts the shader as a full-bleed background behind a container such as <div class="shader-bg" data-shader="ash-and-embers">.
Divi 5: a section layout (JSON, imported through Divi Portability) with the shader as the section background behind a heading, text and button.
Settings: colours, speed and intensity can be set with a data-config attribute or in the CONFIG object at the top of the code. README files document the install steps and settings for both formats.
Under the hood
Single-pass 2.5D layered compositing: domain-warped fBm smoke lit from below, heat-haze refraction, a procedural skyline with parallax layers and up to nine depth-of-field particle layers (thin-lens bokeh), through a shared cinematic lens pass. Plain WebGL2 with inline GLSL ES 3.00, no external libraries.
Settings: colours, speed, fireGlow, smoke, heatHaze, embers, ash, layers, focus, aperture, drift, neonAmount, parallax.
Performance and accessibility

Safe to hand off
Plain WebGL2 with no external libraries. Every shader steps down on its own, so a client's visitors never get a broken section.
