What if I don't want to spend a few weeks learning Blender? What if I just want to spend a couple of hours and get something that's good enough?

If you think the results in that page are "good enough", then I assure you, as a heavy blender and Gen AI user, that it would take you much less time to get this good at blender (about Logo turtle level) than it would to figure out how to run this model yourself locally, with all the headaches attached.

Without question.

Sounds like you're looking for something like an asset store, or open source models.

The best thing you can do is to just make money. I am serious.

The current 3D GenAI isn't that good. And if when they eventually become good enough they won't be very cheap to run locally, at least for quite a while. You just need to wait & hoard spare cash. Learning how to use the current models is like trying to get GPT1 to write code for you.

Then you don't get any positive recognitions for the product anyway.

... is like...

What if I don't want to learn guitar? What if I just want to spend a couple of hours and get something that sounds like guitar?

I tend to say in this situation: you can do that. Nobody's stopping you. But you shouldn't expect wider culture to treat you like you've done the work. So what new creative work are you seeking to do with the time you've saved?
