Hey Product Hunt 👋 Today we are launching Dimension - a world building agent. I've spent the past 3 years building and training diffusion and super resolution models, and I saw creators hit the same wall over and over: $6+ for a 10-second clip that takes 5-10 minutes to generate, and one bad take means starting all over. In essence, creators dump hours re-prompting for a few-second clip. The real bottleneck isn't the model. It's the input modality. Here's how dimension solve this: the agent builds a full pre-vis that replicates the exact object physics, rigging/animation, environment, camera paths - every detail locked in before generation ever starts. Think of it as a low-poly but still detailed version of your final shot with the actual choreography already baked in. From there, the diffusion model isn't guessing at motion or composition anymore - it's simply responsible for what you'd expect out of post-production: photorealistic texturing and materials, subsurface scattering on skin, physically accurate lighting, etc... Its so simple too: - Log in - Create a new canvas - Enter the 3D stage - Build your world with the agent - Hit Finalize, bringing your pre-vis to the canvas - Pass it to any diffusion model Its completely free to try: https://dimension.so/ We are still early, and any feedback would be really helpful! If the problem and the promise resonate - I’d love for you to try Dimension and tell me what you think. How are the outputs? Does it fit into your creative workflow? What is missing? That feedback would help a lot! Let's kill the stigma around AI Video generation!
