@p0lybenderSomeone handed GPT-6 Astra an old drawing of a steam train and asked it to rebuild it in Blender. not a reference photo. not a 3D scan. a drawing. a few minutes later: 3,295 fully editable objects. complete geometry. every component individually selectable and modifiable. the wheels. the boiler. the smoke stack. the coupling rods. all of it reconstructed from a flat image into a working 3D asset. here's what that number means in practice a mid-level 3D artist modeling a detailed steam train from scratch takes 40-80 hours. they produce one mesh, maybe a few hundred objects if they're being thorough about modularity. Astra produced 3,295 in minutes. and every single one is editable. you can pull the wheel off and resize it. change the boiler length. swap the cab design. it didn't generate a static render - it generated a working file. the prompt at the end broke me: "go build your own transport tycoon" that's not a joke. the barrier between "i have an idea for a game" and "i have the 3D assets for a game" just collapsed to one image and a few minutes. an old drawing. a single session. 3,295 objects. the 3D modeling industry is not ready for what the next 12 months look like.
