Working on inspection and editing tools for #threejs (Needle Engine, R3F, vanilla, Spline, model-viewer). Early screenshots below, UI has already improved :) Everything is undo-able and is/will be AI compatible.

I'm very excited for this to land in Needle Engine.
It makes responsive timeline animations super easy and artist friendly. You can visually setup view-boxes + control animation based on HTML elements on screen.

We still have some work to do until it's ready but it's already very promising! #three

Some recent paintings... Last one (the frog) just finishing up. All #gouache. I'm glad i started doing this again - to process feelings or to calm down.
