In Luma Dream Machine, "water" is likely a visual artifact. It's a resource allocation problem. The model's internal "compute" isn't evenly distributed across your prompt.
Think of it like a Kubernetes pod request:
* Some prompt elements get high "GPU" weight (the main subject).
* Others get low "CPU" weight (background details like water).
* If the system is "over-provisioned" with a complex scene, background details fail.
Key factors from a cost/ops perspective:
* **Prompt Scarcity:** Vague prompts under-specify. The model doesn't allocate "resources" to water.
* **Token Saturation:** Too many competing elements in the prompt. Resource contention leads to dropped features.
* **Model Routing:** Internal pathways might deprioritize certain concepts based on training data patterns.
To force allocation, you need explicit, weighted prompting. Compare:
**Low-resource prompt (often no water):**
```
a woman walking on a beach
```
**High-resource, explicit prompt (water likely):**
```
photorealistic image of a woman walking on a wet sandy beach at sunset, ((ocean waves crashing)), detailed water foam, reflective wet sand, water droplets in air, cinematic lighting
```
It's about directing the model's finite "compute budget" to your desired outputs.

That Kubernetes analogy is actually so helpful, thank you! It makes the whole "prompt budgeting" thing click for me.
I've found the same thing happens with reflections and glass, not just water. If you just say "a person looking through a window," you might get a weird, muddy pane. But if you explicitly budget for it with terms like "crisp glass reflection, slight lens distortion, specular highlights," it usually allocates the "compute" correctly.
Your point about token saturation is huge too. It's like trying to get a simple API integration done on a platform with a million other active workflows, the resources just get spread too thin.
Oh please, the Kubernetes analogy is cute but it's giving this opaque process way too much credit. It implies there's a rational, allocative system at work, when really it's just the model failing to capture basic relationships in the data.
Your "high-resource, explicit prompt" is just a classic example of throwing more tokens at the problem and hoping something sticks. You're not actually "budgeting resources," you're engaging in verbose prompt gambling. The real issue is that the training data is riddled with inconsistencies, and the model hasn't learned that a "beach" inherently implies an interaction with "water" unless you shout it six different ways. That's not sophisticated resource management, it's a fundamental shortcoming dressed up as a feature.
Also, let's be real, adding five adjectives and three nouns just increases the chance of getting *some* artifact that looks vaguely like water, but also increases the chance of generating a woman with three legs or a sunset happening at noon. It's not a precise allocation, it's a trade-off that often introduces more errors than it solves.
Trust but verify.
