Asked Opus 4.5 to make a marketing video for my OSS project, [@]firtoz/router-toolkit.

It wrote the script, generated voiceover + word-level timing (@elevenlabs.io), created the logo (Nano Banana), built animated scenes with Remotion.

All in one chat session.

What do you think?

Greybox Vision Frame is live! Using Greybox AI scene generator you can type a few words only to build a 3d scene, can go into Vision Frame and play around with your imagination with many variations!

We're looking for feedback and opinions, please give it a try!

If you're deploying on cloudflare, for some reason, the magic headers will not be in the responses for some assets, so you will need to make sure to deploy on a custom domain and then add response header modifications like this:

Teasing a live two way sync between @unity.com and @threejs.org, would be curious to hear thoughts on it! It works also between multiple unity computers or multiple web views. For collaboration in level creation etc. Integrating into @greybox.app soon.

Deployed TRELLIS, the image to 3D model from Microsoft on @replicate.com, you can find it at replicate.com/firtoz/trellis ! When it's warm, takes 30s to generate a 3d model from an image. Otherwise, cold boot takes a few mins.

Interesting... the VTT seems to be not really accessible (hiding below the controls) and the timing is off. Who do I ping about this? @support.bsky.team

New changes for @greybox.app, inspector panels and rotation gizmos. Inspired by the various UI controls such as Figma and Unity. We're trying to get to a comfy and useful UX. I'm very happy with the drag-based inspector value editing. Needs a few more iterations...

Saw a post from another place, had to share it here.

"been doing sim and vfx studies 4 yrs ... Bifrost MPM is just mind-blowing. The sim quality and performance are on another level. ... I think it's better than Houdini.
Made in Maya and Bifrost, rendered with Arnold"

Cursor's 0.43 update looks very exciting, with a new "agent" mode.

Undo/redo is hard, multiplayer 3D undo/redo is hard hard :/ but, I'm quite happy with the state so far! #buildinpublic

So excited to see that people are trying out our product which we just launched in alpha :D #buildinpublic

And very nervous about their feedback 😅

Calling all world builders - @greybox3d.bsky.social is out in alpha!
For #Blocktober last day, here’s a 20-min mockup of Arrakeen Palace from Dune, put together by our cofounders (not pro 3D artists, we promise 😉).
