What's new

Version 3.1

Release date: March 19, 2025

MacOS support

A long-awaited addition! Pixyz Plugin for Unity is now also supported with macOS, unleashing the power of Pixyz import and dataprep technology to Mac users 🍏.

See Compatibility page for more details.

Easy Ambient Occlusion baking

Ambient Occlusion (AO) improves realism by simulating real-world shadowing. Baking AO information in textures is crucial in real-time 3D applications for balancing performance, quality, and control, enabling the creation of rich models without sacrificing interactive performance. Asset Transformer Toolkit 3.1 introduces an easy-to-use action for baking Ambient Occlusion (AO) maps directly in the Editor without requiring artistry skills or the need of an external DCC tool.

Better support for large files

Asset Transformer Toolkit introduced a new import process which generates a prefab out of the source model, through the creation of an Importer asset. This method shows its limits when importing very large files containing a lot of objects, because of a limitation in the number of objects the AssetDatabase can reference, which increases import time significantly.

The 3.1 introduces back and improves the legacy method Import as a scene, where GameObjects are created directly in a new scene (instead of serialized in a prefab), allowing to import large models with performance.

Improved baking capabilities

Texture baking is at the core of many dataprep and optimization features of Asset Transformer Toolkit. In 3.1, it was improved on many aspects:

  • GPU-accelerated baking is now used by default and comptible with all features leveraging baking, making it faster than ever. For CPU fallback, a new Baker Mode project setting gives the ability to choose between GPU- and CPU- accelerated baking mode.
  • Lots of bug fixes making baking more robust (e.g. fixed textures baked too dark with HDRP)
  • A new Offset parameter was added to the Retopologize action, to reduce baking artifacts with overlapping/nearby surfaces:

Tight mesh impostors

Asset Transformer Toolkit 3.1 introduces "tight mesh" rendering for impostors, resulting in improved performance!

Previously, impostors were rendered on a quadrilateral mesh (quad), which, although functional, resulted in wasted space around the impostor that affected performance. Asset Transformer Toolkit now renders impostors directly on a mesh that better conforms to the shape of the original model, minimizing overdraw.

Other new features and improvements

  • New Asset management doc page, explaining behaviors with prefabs created or modified by Asset Transformer Toolkit.
  • New Save Textures as png project setting, saving baked and imported textures as separate png files.
  • Improved Rule Engine filters & actions (new filters, improved UI...).
  • Updates to latest versions for file formats supported at import.

Known issues

  • Importing FBX or Collada files with the macOS version may cause the Unity Editor to crash (patch in progress).
