aeTransform (iTransform_ae) is a lightweight Smart Transform Gizmo for small adjustments to elements without using heavy distortion methods. Unlike IDistort or GridWarp, it performs quick modifications without slowing down scripts.

Key Features

Ultra-Lightweight Processing – No need for warps or distortions
Precise Local Adjustments – Modify specific areas with masking controls
Ideal for Small Transformations – Perfect for minor shape adjustments
Fast Performance – Works efficiently without slowing down scripts

How It Works

Uses a basic transformation model instead of resource-heavy warping
Allows scaling, rotation, and positional adjustments efficiently
Masking support lets artists define specific transformation areas
Works independently of Nuke's distortion nodes

Best Use Cases

Refining rotoscoped elements – Small refinements to rotoscoped shapes
Correcting minor misalignments – Fix small shifts without excessive re-tracking
Masked transformations – Apply localized transforms to specific image areas
Fast motion adjustments – Aligning layers, match-moving, or quick position fixes

How to Use

Download from Nukepedia or GitHub; add the gizmo to your script and restart if needed
Connect the input image; adjust position, rotation, or scale
Enable the mask input to control which areas are affected
Toggle bypass to compare before and after

Best Practices

Use for small, precise transformations—avoid large-scale warping
Combine with RotoPaint, Tracker, and Transform nodes
Precomp static transformations when using multiple Smart Transform nodes

Common Mistakes

Applying large distortions (use GridWarp or IDistort instead)
Forgetting to use masking for targeted transforms
Stacking too many transformations (consider merging transforms)

For small transformations, aeTransform is faster than IDistort or GridWarp. For complex warping, use those tools instead.
