Monday, February twentieth, 2023 | Posted by Jim Thacker
Ubisoft Singapore senior technical artist Mohsen Tabasi has launched StableDiffusion_Houdini 2.0, the newest model of his free software that hyperlinks Steady Diffusion into Blender.
The plugin makes it attainable to make use of the open-source AI image-generation mannequin inside Houdini, to be able to use 3D scenes to information the picture that Steady Diffusion generates.
With it, customers can convert renders of straightforward blocking geometry into detailed illustrations and idea artwork.
Model 1.0 required a web-based Stability AI DreamStudio account to generate photos, however model 2.0 makes it attainable to arrange a server based mostly on open-source software AUTOMATIC1111 and run completely on an area machine.

Convert easy 3D geometry into illustrations or idea artwork in a variety of visible kinds
Open-sourced final yr, and a part of a new wave of AI artwork instruments, Stability AI’s Steady Diffusion mannequin generates 2D photos based mostly on consumer’s textual content prompts and, optionally, information photos.
StableDiffusion_Houdini makes it possble to make use of a 3D scene to generate that information picture, utilizing Houdini’s Procedural Dependency Graph (PDG) to submit a local Houdini render of the scene because the init_image.
That makes it attainable to make use of easy blocking geometry to generate detailed idea artwork or illustrations.
The 3D scene largely dictates the composition of the picture, to which Steady Diffusion transfers a brand new visible model – one thing that may be guided by coming into textual content prompts inside Houdini.
The preliminary picture and the Steady Diffusion output are each proven in a Houdini compositing viewer, and you too can modify Steady Diffusion parameters inside Houdini to regulate the look of the ultimate picture.
Can now run completely on an area machine
On its unique launch final yr, StableDiffusion_Houdini required you to attach an official Stability AI DreamStudio account to be able to generate photos.
Signing up for an account is free, however producing photos consumes credit, and DreamStudio generates photos below a CC0 licence, which limits their use in industrial tasks.
Nonetheless, StableDiffusion_Houdini 2.0 provides the choice to put in a server working open-source Steady Diffusion UI AUTOMATIC1111 in your PC, and connect with that native server.
(AUTOMATIC1111 additionally consists of a variety of helpful extras together with AI-based picture upscaling and face restoration instruments, though we aren’t certain whether or not you may management them straight from inside Houdini.)
Additional studying and associated instruments
As ever, earlier than utilizing Steady Diffusion, it’s value studying up about its strengths and limitations: The Verge has abstract of the broader copyright and moral points posed by AI artwork instruments.
In case you’re wanting to make use of Steady Diffusion with different DCC purposes, we’ve beforehand lined AI Render, a free add-on that integrates Steady Diffusion into Blender in a similiar means.
Licensing and system necessities
StableDiffusion_Houdini 2.0 is on the market as a Houdini Indie .hdalc file below a MIT licence.
AUTOMATIC1111 is on the market as a compiled binary for Home windows 10 and Nvidia GPUs solely, although it additionally runs on AMD and Apple Silicon in case you set up from supply. It’s out there below at Affero GPL licence.
