Quick answer: Author aim offset poses additively against the base pose, drive the blend space with correct aim angles, and apply it on the right bones.

An aim offset not blending is an additive or blend-input problem. Here is how to fix it.

How to fix it

1. Author additively against the base

Aim offsets are additive poses layered on the base aim pose. Author them against the correct reference so they add the aim delta, not a full pose. A wrong reference distorts the result.

2. Drive with correct aim angles

Feed the blend space the correct horizontal and vertical aim angles (clamped to a natural range) so it interpolates between the offset poses smoothly. Wrong or jumpy inputs make the aim snap.

3. Apply on the right bones

Apply the aim offset to the upper body bones (spine, arms) so the character aims while the legs keep their locomotion. Applying it to the whole body, or the wrong bones, breaks the pose.

Catching the ones you can't reproduce

The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.

Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.

This is where a tool like Bugnet earns its place. Its SDK captures every error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.

Reproduce it once with full context and the fix writes itself. The hunt is the expensive part.
