PartCrafter vs Scenario

PartCrafter is a free, open-source model that generates multiple 3D parts and objects from a single RGB image. It can handle individual objects and complex scenes, producing distinct meshes with meaningful part structure without requiring a pre-segmented image. Its architecture represents parts with disentangled latent tokens and uses hierarchical attention to pass information within and across parts. Local inference scripts can remove backgrounds and optionally apply style transfer to adapt real-world photos toward the rendered-image domain used for training. An optional vision-language feature can suggest the number of parts; Gemini is the default provider, and the provider architecture can be extended. Pretrained object-level and scene-level weights are hosted on Hugging Face. Installation is from the GitHub repository in a Python environment, and inference requires a CUDA-enabled GPU with at least 8 GB of VRAM. The linked Hugging Face demo is paused, though its page says users can ask the authors to restart it. The repository lists an MIT license and provides the software as-is, without warranty.

Scenario is a creative AI platform for making workflows across image, video, audio, and 3D content, available through a web app and API. Its tools include media generation and editing, model training, upscaling, and background removal. Users can train custom LoRA models on reference images to align generated assets with a creative style or brand guidelines. The library offers models from more than 50 providers, with visual node-based workflows, batch generation, reusable templates, and API-connected agents. Scenario says its API can integrate with Unity, Unreal, or custom pipelines. The company states that it is SOC 2 Type II certified, supports SSO/SAML, and does not reuse customer data to train its models; its Trust Center lists encryption at rest and in transit. The free tier provides 50 daily credits for personal and evaluation use. Paid plans include a full commercial license and start at $15 a month for Starter; Pro is $45 a month and Max is $75 a month. Credits depend on model and output settings, and unused credits do not roll over.
