Grip Studio
Hand Pose + Object Grip Authoring
Weapons, tools, props, and interactables should remember how they are held. Grip Studio turns that relationship into reusable, object-owned data you can author, inspect, prove on the full character, and apply at runtime.
VERSION 1.0.0 EDITOR Unity 6+ SOURCE Included STATUS Release stage
The central idea
The grip belongs to the object.
A pistol knows where its primary palm lands. A rifle knows where its support hand belongs. A carried prop knows its hold pose. Characters consume that relationship instead of each rebuilding it from scratch.
Change characters, animation clips, or runtime systems without losing the authored intent that lives with the prop.

The authoring loop
From raw prop to a grip you can trust.
One continuous workflow, with the hard questions surfaced before runtime.
02
Place Set the palm in context
Click directly on the object to establish the physical grip point and its object-local relationship.
03
Shape Wrap, then refine
Use contact-aware finger wrapping, portable semantic curls, or exact three-axis joint controls when needed.
04
Prove Check the whole character
Review reach, wrists, stance, clearance, movement, and primary/support hand roles on the complete Humanoid.
05
Apply Ship the relationship
Save the grip with the object, test it in the generated Playground, then drive it through the included runtime APIs.
System capabilities
Precision without the ritual.
Start with the fast path. Reach for exact control only where the asset actually needs it.
OBJECT / OWNED 01
The object carries the truth
GripProfile, GripPose, GripSocket, and GripObject keep grip data with the prop that owns it—not scattered across character prefabs and controller states.
CONTACT / AWARE 02
Place once. Wrap intelligently.
Palm click placement and mesh-aware finger wrapping turn the repetitive first pass into a focused authoring step.
DUAL / HAND 03
Primary and support roles
Author pistols, rifles, carries, tools, and other two-handed relationships without flattening both hands into one pose.
RIG / PORTABLE 04
Portable where it matters
Object-space palms and semantic finger channels carry across compatible Humanoids, while exact rig-local overrides stay available for precision work.
WHOLE / BODY 05
A hand pose is not enough
Check arm reach, wrist alignment, stance, movement, and clearance before the grip gets anywhere near production.
RUNTIME / OPEN 06
Your gameplay stays yours
GripReceiver, GripApplier, and GripSession handle grip application and transitions without replacing inventory, networking, input, or animation state logic.

Readable evidence
Every grip can explain itself.
Grip Passports turn authored data into deterministic blueprint-style previews for the launcher, library, Grip Story, and image export. The result is quicker review and less guesswork when a profile moves between teammates, characters, and scenes.

SCOPE / HONEST
It authors the grip. It does not take over your game.
Grip Studio does not replace inventory, networking, input, weapon logic, pooling, or your animation state machine. Its compatibility evidence applies to the exact character and pose context you review. Surface fit, rig-local joint rotations, and body reach should be checked on every character you intend to ship. That boundary is deliberate.
Questions, answered
Before you author the first grip.
Does Grip Studio replace my inventory or weapon system?
No. Grip Studio authors and applies grip relationships. Your inventory, networking, input, weapon logic, pooling, and animation state machine remain yours.
Can one object have more than one grip?
Yes. An object can own multiple named poses, including one- and two-handed variants with explicit primary and support roles.
Will one pose work on every Humanoid?
Object-space palms and semantic finger channels are designed for portability across compatible Humanoids. Exact joint overrides, body rotations, reach, and surface fit still deserve review on every character you ship.
Is an IK package required?
No. The core has no third-party dependency. Optional bridges are included for Unity Animation Rigging and other supported integrations when your project already uses them.
Why is the Asset Store button not active yet?
Grip Studio is in the release stage. The product page is live while final package validation and the Asset Store listing are completed.
