ImGuizmo scale hover/drag relies on ray-plane intersection with the axis as plane normal; in front views (axis ⟂ camera-to-object) the intersection numerator is identically zero, so handles can't be grabbed and values jump randomly; axes parallel to the view have zero screen displacement. Submodule is read-only and AxisMask can only hide degenerate axes, not replace them. Replace the library scale path entirely with a screen-space gizmo: - three axis rods (line + end square) + center uniform-scale square, constant screen size in any view - axis drag: mouse delta projected onto the axis' screen direction - axis pointing at camera: radial mapping (drag away = grow) - center square: uniform scale (library MT_SCALE_XYZ semantics) - Ctrl snapping quantizes the result; scale clamped >= 0.01 - pick suppressed while hovering/dragging the self-drawn handles
