Unlike previous models, the pose-dependent blend shapes are a linear function of the elements of the pose rotation matrices. The parameters of the model are learned from data including the rest pose template, blend weights, pose-dependent blend shapes, identity-dependent blend shapes, and a regressor from vertices to joint locations. Our Skinned Multi-Person Linear model (SMPL) is a skinned vertex-based model that accurately represents a wide variety of body shapes in natural human poses.
Please send your queries to: or present a learned model of human body shape and pose-dependent shape variation that is more accurate than previous models and is compatible with existing graphics pipelines. The original 300-dimension shape space of SMPL and related models (MANO, SMPL+H, SMPL-X) is available upon request. You can download SMPL with up to 16 shape components, and in several standard versions (male, female, gender neutral). Please find more information for these at the links below: SMPL is also available with articulated hands and expressive faces, and can be estimated from images. For the latest upgrade to SMPL, check out the STAR Model (ECCV 2020) here: After registration you will be able to access the Downloads menu at the top menubar. Please register to download SMPL and related tools for using SMPL in different animation environments. This site provides resources to learn about SMPL, including example FBX files with animated SMPL models, and code for using SMPL in Python, Maya and Unity. That tutorial course was originally born out of collected knowledge from previous Open Movies such as Spring.īut since the features and workflows of realistic character creation are not as easy to follow and use, we decided to leave this in its current format until another time.SMPL is a realistic 3D model of the human body that is based on skinning and blend shapes and is learned from thousands of 3D body scans. The original intent was to turn this documentation into a full tutorial series similar to the Stylized Character Workflow. The main topic will also be on the sculpting and modeling process for animation, instead of the whole workflow of texturing, shading, grooming, rigging and animation. It will not go into detail like other tutorials on this platform. This documentation is focused on advanced techniques and general advice that was learned during production. This documentation will remain more generalised to apply to other characters outside of that production as well. Based on actual movie productionĪll the content is closely tied to Project Heist and will often use it as a visual reference. This section was mostly compiled from previous work and research from the Blender Studio. In this documentation we share all the current research and workflow techniques on creating highly realistic human characters in Blender.
