Input: video or words
Plask turns a video of someone moving into 3D motion, which is ideal when you can perform the action. Nira generates motion from a text brief, which is ideal when you cannot, or when you want many variations quickly.
Characters
Nira auto-rigs the mesh you upload, including quadrupeds, birds, dragons, and other non-humanoids, and animates them from text. Plask is built around capturing human performance and applying it to humanoid characters.
Export
Plask exports GLB, FBX, and BVH. Nira exports GLB and GLTF. If your pipeline needs BVH or FBX specifically, Plask has the edge.
