How It Works

From Prompt to Nightmare

A complete walkthrough of the CRTM Codex pipeline, no experience required.

The CRTM Codex is a step-by-step prompt course that turns AI image and video tools into a real creature-design pipeline. Here's exactly what that looks like, from a blank prompt to a finished creature in motion.

What Is a Prompt?

A prompt is just a written instruction, a few sentences telling an AI image tool exactly what to create. You don't need to know any special syntax or code. The CRTM Codex gives you 73 tested, ready-to-use prompts across 7 full sections, so you're never starting from a blank page or guessing what to type. Just follow along.

What You Need to Get Started

✓A Google Gemini account (free tier covers most exploration)
✓A KlingAI account (for bringing creatures to motion; this is where credits get used more seriously, as a natural next step)
✓No prior AI experience
✓Whatever art background you bring (from decades of sculpting and design to none at all) works here

Real example

The CRTM Codex Creature Creation Pipeline

Chimeran Splicer pipeline: four clown and contortionist reference photos fused into a clown creature, then composed into an abandoned carnival at sunset

AI Prompt: Chimeran Splicer — combine Muscular Body build with Red-Haired Clown face paint and features, Evil Clown expression, and Contortionist limb structure.

Result: Chimeran Splicer — the fused creature design, before any environment is applied.

AI Prompt: Chimeran Crafted Environment — composites your creature into an environment built entirely from its own design. The full prompt lives inside the Codex.

Step 1: Source Material

Muscular Body (Pexels-Mike-Jones) + Creepy Clown, Red Hair (Pixabay-kalhh) + Evil Clown, Black Hair & Yellow Teeth (Pixabay-Ernesto-Rodriguez) + Contortionist Couple (Pixabay-trungkhang)

Step 2: Chimeran Splicer Result

AI Prompt: [Chimeran Splicer] Combine [Muscular Body] build with [Red-Haired Clown] face paint and features, [Evil Clown] expression, and [Contortionist] limb structure.

→ Result: the fused creature design, before any environment is applied.

Step 3: Chimeran Crafted Environment Composition

AI Prompt: [Chimeran Crafted Environment] Composites your creature into an environment built entirely from its own design. The full prompt lives inside the Codex.

→ Result: the finished creature, composited into its own environment.

Every source photo used to build the examples throughout this toolkit comes from Unsplash, Pexels, and Pixabay, all platforms where photographers have knowingly licensed their work for free use like this, commercial included.
