ACCOMMODATE SCAN & SCULPT POSES

Scan Poses

Scan poses come in various standards — depending on the camera setup of the scan studio — which AccuRIG is well-equipped to solve. Having handled hundreds of scanned ActorCore characters, AccuRIG has a proven track record of optimizing mass production and scan-to-animation workflows.

SCULPT POSES

3D models sculpted with the likes of Zbrush range in size, style, and posture. These unpredictable factors pose no challenge to AccuRIG’s ability to make accurate analysis and deploy the correct strategy for naturalistic rigging.

  • Axis Correction
  • Twist Bones

Arm and hand positioning can complicate the rigging process with mesh misalignment and awkward joint angles. AccuRIG responds with cutting-edge solutions for proper joint rotations that make dynamic performances anatomically correct.

Turning the palm to its limits can wring the forearm mesh. To overcome this unsightly artifact, AccuRIG allocates additional bone segments to smooth out the mesh by redistributing the skin weights.

ACCURATE BONE PLACEMENT

Apart from dealing with realistic human shapes, AccuRig excells at rigging models with oversized head, obscured shoulders, beast legs, even hand holding accessories, those unexpected character silhouette has failed most traditional auto-rigging technologies.

  • Head
  • Legs
  • Accessory

Amorphous Head Geometry

AccuRig correctly positions the head bone, even on characters with obstructed heads and necks. Let AccuRIG handle complex setups like hair covered shoulders and loosely-worn hoodies, then tweak the joint positions when needed.

Hind Legs

Not only does AccuRIG handle bipedal characters, it also correctly generates hind legs for fantasy creatures such as beastmen, minotaurs, goatmen, and even birds. Artists can further refine joint positions from the orthographic side view.

Accessory

AccuRIG differentiates the hand from the props being held so auto-generated bones don’t extend into inanimate objects. Instead of distorting the limbs, skin weights for the body remain intact and do not spill into other objects.

SKIN WEIGHTING

The animation quality of a rigged character is highly dependent on the proper skin-weight assignments related to its governing bones. AccuRIG mimics the weight-paint patterns of professional riggers for natural articulation of the body joints.

  • Accessory
  • Clothes

Oversized Hair

Deploy appropriate skin weights for the head and neck, despite the immensity of hair with outsized share of the overall mesh.

Knees

By partitioning skin weights, AccuRig retains volume around the knees that account for central bones and surrounding musculature so they bend with anatomic accuracy.

Elbows

With accurate skin weight distribution, AccuRig preserves elbow volumes to keep them solid and shapely as they bend to their maximum limits.

Hands

Bend finger joints with reckless abandon and leave the biomechanics to AccuRIG. Knuckles stay solid and angular while fingers remain fleshy and supple, even when the hands are clenched. Thumbs do not contort, rather, they bend naturally and settle in comfortable positions.

Accessory

Traditional auto-rigging techniques simply deploy skin weights by proximity. As a result, weights permeate surrounding areas to nearby meshes that distort when animated. By contrast, AccuRIG segregates skin weights by detecting individual surfaces and tracing back to their rightful parent bones.

Clothes

Complex portions of the clothes with equally clunky weights — particularly around the crotch and armpits — do not get pulled in all directions or favor one side over the other when spread apart.

PRECISE FINGER RIG

Finger Separation

By shrinking the finger voxel volumes before generating the hand joints, AccuRig accurately rigs the fingers even if they lie close together.

Diverse Finger Types

Artists can dream up character models of all shapes and sizes then deploy rigs without encountering limitations.

JOINT MASKING FOR OFFBEAT RIGGING

Mask away unwanted joints for partial rigs on models with incomplete limbs and non-standard poses.

CONVERT TO POPULAR FORMATS

Save characters rigged with AccuRIG in standard FBX and USD formats, then export to other popular 3D platforms such as Unreal Engine, Unity, Blender, iClone, Omniverse, Maya, 3ds Max, MotionBuilder, Cinema 4D, and any other 3D tools.
