Playbook is an online service-based Stable Diffusion, trained specifically to generate output that looks like it was 3D rendered from textured meshes.
You can already do this on a local install of the free Stable Diffusion, with free LORA ‘plugins’. There thus seems no reason to pay for such a thing, unless Playbook…
– is remarkably better than normal Stable Diffusion;
– is more stable (at following text prompts);
– can generate 100% stable characters along with stable outfits and clothing colours;
– can also generate textured 3D meshes which can be exported.
I guess we test it and see.
