Why we like it

Transform Quantizer earns its place in the superhive library by handling a narrow job directly: it performs a purely mathematical rounding of values without trying to be smart, so elements sitting too far from their intended placement may still need manual cleanup.

What is Transform Quantizer?

Transform Quantizer quantizes coordinate values — position, rotation, or scale — to a definable numerical precision threshold, using mathematical rounding or truncation. Rounding the coordinates of elements to the closest grid-aligned point aligns geometry to an orthogonal grid of adjustable size, and the same applies to rotation and scale values.

The add-on is aimed at a few situations: aligning manually placed elements with eyeballed positions or neglected precision, rounding off position, rotation, or scale values, fixing float-point precision issues by cleaning up slightly off values so 1.9999 becomes 2.0, and forcing property values to be integers. It is often used in architecture or when rough, approximate values from manual placement, snapping errors, or imports from other software need cleaning up.

Supported element types include objects (position, rotation, and scale on each XYZ axis), mesh vertex positions, and bezier curve vertex positions, with the option to include or exclude curve handles. Mesh and curve vertices are quantized in Edit Mode, and a Clear Locations command moves selected points to the object's local origin. Documentation is included.

Who is Transform Quantizer best for?

Transform Quantizer is best for cleaning up scenes or models with rough, eyeballed, or imprecise positions, and aligning objects, mesh vertices, or curve points to a grid of adjustable spacing.

How much does Transform Quantizer cost?

Transform Quantizer is completely free to download and use.

Key features

  • Quantizes object position, rotation, and scale for each X, Y, and Z axis, with a separate threshold per axis
  • Quantizes mesh vertex positions per axis in Edit Mode; larger threshold values produce an effect similar to voxelizing the shape
  • Quantizes bezier curve vertex positions per axis, with optional inclusion or exclusion of curve handles
  • Fixes float-point precision issues by cleaning up slightly off values, so 1.9999 becomes 2.0
  • Forces property values to be integers
  • Clear Locations moves selected mesh or curve points to the object's local origin, an Edit Mode equivalent of Alt + G that vanilla Blender lacks
  • Toggles activate individual vectors for easy exclusion from the operation

Frequently asked questions

Does Transform Quantizer work on mesh and curve vertices in Edit Mode?

Transform Quantizer quantizes mesh vertex positions and bezier curve vertex positions along each X, Y, and Z axis in Edit Mode, with a separate threshold available per axis. For bezier curves you can optionally include or exclude the curve handles when quantizing. Applying larger threshold values to a mesh produces an effect similar to voxelizing the shape. Object position, rotation, and scale can also be quantized outside Edit Mode, so the add-on covers both object-level and vertex-level work.

Can Transform Quantizer set a different precision value per axis?

Transform Quantizer lets you set independently adjustable quantization values for the X, Y, and Z axes, so each axis can round to a different threshold. This applies to object position, rotation, and scale, as well as mesh and bezier curve vertex positions. Toggles to the left activate different vectors, making it easy to exclude an axis from the operation. Defining a precision value tends to align elements to a grid of adjustable spacing as a practical consequence.

What does the Clear Locations command in Transform Quantizer do?

Transform Quantizer includes a Clear Locations command that clears the location of selected vertices for both mesh and curves, moving all selected points to the object's local origin. It works as the Edit Mode equivalent of pressing Alt + G in Object Mode, a shortcut that is unavailable in Edit Mode in vanilla Blender. This gives you a way to reset selected point positions to the origin directly while you are editing geometry, rather than switching modes.

Why does Transform Quantizer sometimes leave objects overlapping?

Transform Quantizer performs a purely mathematical rounding of values and does not try to be smart about the result. If elements sit too far from their intended placement, you may end up with overlapping objects or missing grid spaces. When that happens, the wrong results are best fixed by hand, either by moving the objects closer to their desired final position before quantizing, or by snapping them into place afterward once the rounding is applied.

Is Transform Quantizer free to download?

Transform Quantizer is listed as free in this catalog. Licensing terms can change over time, so check the developer's page for the current details before you download. The add-on ships with documentation, and its scope is focused on rounding or truncating coordinate values to a precision threshold you define. It supports quantizing position, rotation, and scale for objects, along with mesh and bezier curve vertex positions in Edit Mode.
