How I make Roblox VFX with Opus 5.5

I type a few sentences, and I get back a completed effect like the one you see above in 30-45 minutes.

Here's how it works:

1. Claude Opus 5.5 designs the effect and writes the Luau

2. Claude uses Blender to model custom meshes, flipbooks, and textures for each effect.

3. If I don't have textures from past effects I can use, Claude generates some textures using GPT image (Higgsfield or NanoBanana work too)

Then, an AI critic watches a screen-recording of the VFX frame-by-frame, and scores it out of 10. It sends back suggested fixes. I don't touch studio at all, Claude does all of this by itself.

4. Blender is used to give each effect a special "feel." For example, Claude used Blender to give the Chain Lightning effect circuit cracks, a shock band, and cinder chunks.

Well, you might be asking, does it actually improve on plain Claude?

Yes, but not in the way you might think.

With pipeline for the black hole effect: 70 mins (slow, I know), and $15 in API costs.

Without pipeline for the same effect: 2.6 hours, $45 in API costs.

Quality actually doesn't improve that much, but the pipeline is more than twice as fast and 3x as cheap.

I'm not going to share the prompts, the recipes, and how the critic decides. A client has already purchased, and it would be unfair for me to share it for free.
