Thanks so much for actually downloading and kicking the tires — and for braving the SmartScreen warning :] This is exactly the kind of feedback I was hoping for.
Gleba looks really cool, thanks for the link. Using CA output as a basis for concept art / worldbuilding rather than a final product is honestly one of the use cases I'm most excited about, so I'd love to see what you end up making with it.
The web demo being stuck on loading — that was 100% on my end, not yours. The CDN was silently re-compressing the demo's files in a way that broke the browser's integrity checks. It's fixed now (verified on desktop) — if you get a chance to retry, a hard refresh (Ctrl+Shift+R) may be needed the first time. Thanks for reporting it; you likely saved me a bunch of silent bounces.
On the eyedropper: Alt+Click already does exactly that from any tool — and you sold me on the GIMP muscle memory, so I've just implemented Ctrl+Click as a color picker while using the Pen, Eraser, or Fill tools too. It'll ship in the next update v0.15.12. (There's also a setting for which tool the eyedropper returns you to afterwards: stay / pen / eraser / fill.) And yes, the "draw in GIMP, bring it into Phluxel, iterate, go back" loop is a fully intended path — PNG/GIF import and clipboard paste both work.
On the rule language — totally fair, and you're not alone. A few things that might flatten the curve:
- Help ▸ Starter Gallery has 20 ready-made scenes/effects; applying one and reading its rule in the editor is the fastest way to learn by example.
- The Rule Editor has a plain-English breakdown panel that explains what each line of the current rule does, plus a cheatsheet of every token with tooltips.
- Many built-in rules expose live parameter sliders, so you can get a feel for cause-and-effect before writing anything.
- There's a Quick Start and a full language reference under Help as well.
If you hit a wall on a specific effect you're trying to make, tell me what you're going for — happy to sketch the rule for you, and those conversations usually turn into better docs/templates anyway. Thanks again for the thoughtful writeup!
