RendersCustom creature rig and animation

Hollowback rig

A custom skinned rig and animation set for Hollowback, our horror entity: 54 bones shaped to its too-long limbs, weights cleaned to Roblox's limits and tested in extreme poses, and three Roblox-ready clips: idle, creeping walk and lunge.

Commission something like this More rigging, animation & renders

Bones: 54; 52 deform, custom layout
Influences: ≤ 4; per vertex, Roblox limit
Clips: 3; idle, creep walk, lunge
Root weights: 0; vertices on Root / HRP
Delivered as: FBX + GLB

Roblox handoff

Hollowback v2's delivered 2048² PBR set, unchanged (+ the 1024² copies): albedo, normal (OpenGL), roughness, metalness, emissive (black)

54-bone custom armature fitted to the creature: two-bone neck, jaw, long four-bone arms, three-joint fingers with claw tips, toe bones
Roblox skinning rules met: max 4 influences per vertex, 0 unweighted vertices, nothing weighted to Root or HumanoidRootPart, weights normalised
Heat weights as a start, then hand-tuned joint falloffs at the elbows, knees, neck and armpits, checked in six extreme poses
Three clips at 30 fps: Idle (loops), CreepWalk (loops in place, about 2.9 studs per second), Lunge (starts and ends on the idle pose)
Feet solved with IK and baked, so planted feet don't slide; every clip round-trips through FBX within 8 µm of the Blender rig
One FBX per clip for Roblox's Animation Editor import, plus the rigged mesh FBX and a GLB with all three animations

How Hollowback was built.

Every stage of Hollowback rig, from the first cage to the Roblox check, recorded straight from the Blender viewport. 19 seconds, 15 stages.
