ACT is Many Tools for Game Asset Creation (Batch Export FBXs/GLTF for Unity/UE/Godot, Origin Aligment Tool, Renaming, UV Tools, Low-Poly Art workflow tools, etc.) for Blender.
- (2025.1) Blender 4.2+ (from Blender Extensions)
- (2025.1) Blender 4.2+ (from GitHub)
- ACT Unity Editor Script (for Unity 2022+)
If you want to support me you can buy this addon on Blender Market

[FIX] Clear Custom Normals apply on meshes with custom normal data only
[IMPROVEMENT] Rename UV: Set Default name for UV when "Name" Field is empty
Aligment Origin Point to:
- Max/Min/Middle point of object for X, Y or Z axis
- 3D Cursor (Separate Axis)
- Coordinates (Separate Axis)
Set Origin Point to Selected Element(s)
Delete Blender's default numbering and add new numbering by Axis/Outliner order with pattern:
- xxx_1, xxx_10, xxx_100
- xxx_01, xxx_10, xxx_100
- xxx_001, xxx_010, xxx_100
Add/replace/remove postfix _LOD* with a selected LOD level.
Quick add suffix .L or .R to Selected Bones.
- Batch Renaming UV by Index (example, Lightmap - second uv channel)
- Batch Add UV with custom name (copy UV from active, smart projection or lightmap uv)
- Batch Remove UV by Index
- Set Active UV Layer for Selected Objects in 3D View and Image/UV Editor by UV Index
Batch assignment of UV seams to models directly from Object Mode.
Tool for easier Atlas Packing.
- Scale UV with power of 2
- Move UV with steps
Batch Export Selected Objects for Unity, UE or Godot. Available some modes:
- Export All Selected Object into One file
- Export Each Object into Individual file
- Batch Objects by Parent
- Batch Objects by Collection
Now ACT has two different algorithms for export FBXs to Unity: "Unity" and "Unity (Legacy)".
This profile supports Objects with Linked Data, more acurate for rigs, animations, angles and axis. But this export profile requires additional steps with models in Unity. You have to set in model import settings "Scale Factor" to 100 and check in option "Bake Axis Conversion".
For automatization this steps I created Unity Editor Script and you can use this different ways:
- Select Models -> RMB -> ACT/Fix Models Transform.
- Open ACT Settings Window (Window -> ACT -> Settings) and enable Models Postprocessor. It automatically set import settings for each model (or for models whose names contain the specified string or character).
The Unity editor ACT script is distributed with the ACT Blender add-on.
But you can also use previous algorithm: This algorithm doesn't require additional actions in Unity and this Export Profile provide back-compatibility with already existing models.
Transfer Material Base Color to Viewport Color for Solid View Mode. Or Generate Random Colors for Materials for Viewport.
Just remove all UV Maps or all Vertex Colors from selected objects.
Delete from selected objects unused materials (not applyed to faces) and unused material slots.
Create Palette Textures (32x32px) for Selected Objects painted with colored materials. In one palette texture can be up to 256 colors (materials).
Assign active material to selected faces in MultiEdit Mode.
Remove duplicate materials (by name). Useful when importing many models with the same materials but from different files. In this case, Blender creates many copies of the materials. This function allows you to find and assign the original materials to all models.
Copy Object Name to Mesh/Font/Etc.(Data-Block) Name.
Transfer Collection Name to Object Name. You can use dirrernt ways for that:
- Added Collection name before or after current object name. For example, "CollectionName_ObjectName" or "ObjectName_CollectionName"
- Replace Object Name to "Collection Name + Type + Numbering", For example, "CollectionName_Mesh_001" or "CollectionName_MESH_001". Thanks @Oxicid for implementation!
Clear Custom Normals and set Autosmooth to 180 degrees for Selected Objects.
Flip or Recalculate Normals for Selected Objects in Object Mode.
Tool For Easy Simplifying Armature: Delete (or Dissolve) Selected Bones (Exclude Active) and Transfer Vertex Weights to Active Bone.
In game development, objects with negative scale should be avoided (especially colliders or other physical objects). This tool allows you to find such objects.
Removing empty spaces under which there are no objects and meshes without geometry.
Remove stitches one by one (starting from the selected edge). Perfect for simplifying cylindrical geometry.
Collapses edges one by one (along the loop). Perfect for simplifying spherical geometry.
