A way to adjust the snapping behaviour of the scale gizmo so the scaling is not applied to current values.
When scaling a mesh with snapping I want the scaling values to increment like so:
1500 → 1505 → 1510 → 1515 → …
When scaling a mesh using the gizmo scale snapping feature, the current behaviour is the following (snapDistance: 0.05):
1500 → 1575 → 1654 → 1737
The new “snapped” scaling value applies to the current scaling, so 1500 * 1.5 = 1575, and so on.
This makes it really hard to precisely align the scaling of 2 meshes to have the same value in the end.
A way to change this behaviour to incremental snapping would be a great addition to have for the scaling gizmo
