You can use the +/- button to add / remove blend file to the libraries list. Press the Selector button to open the asset selector. You can also use default hotkey Shift + Enter.

Batch Import

You can batch import all assets (fbx, obj, 3ds, blend) in a folder with “Batch Import” panel. All subfolders is also imported to sub collections.

Rename Object	Rename the object with the file name.
Rename Mesh	Rename the mesh data with the object name.
Override Transform	Change the rotation and scale after import.
Apply Transform	Apply rotation and scale after import.
Align to grid	Align each asset row by row and column by column.
Row	Asset number for each column.
Adjust Location	Place the asset using bounds center.
Adjust Size	Resize the asset to fit one unit cube.
Restart Collection	Restart on each collection.
Rearrange	Rearrange exist assets in active collection.

Generate Preview

To has preview in asset selector, you need to generate preview in the blend library. The image is saved with the same name as the object and packed in blend file.

PNG / JPG	The image file format.
Size	The size of image.
Use scene world	Use the world in current scene; otherwise, a simple world with single color is used.
Use Alpha	Save with alpha in image.

Replace Materials

Help you batch replace materials assigned to objects. Select the material you want to replace to. Enter pattern (Regex) of materials name to replace with. All materials name match the pattern is replaced to the selected material.

Rigid Body Helper

Help you to create the rigid body proxy objects and settings. Most game assets pivot point is not in the center, and may contain children objects. Using that object with physics has wield result. “Rigid Body Helper” creates a proxy object join with all children and set the origin to center of mass. After simulation, the proxy data is transferred back to original objects.

Asset Selector

Asset Selector allows you to select asset and place the asset to the scene. Only objects without parent is shown in selector, all children of object is grouped as a single asset. The image with the same name as the object is shown as preview.

Ctrl	Hold Ctrl and move mouse to scale object.

Scatter Mode

Place the asset using scatter mode. Press 3 to activate.

Radius	The radius to scatter objects.
Density	The number of object to scatter.
Interval Scale	The ratio of radius that the minimum distance to scatter new objects.
Interval Min	The minimum distance to scatter new objects.

U	Toggle uniform.

Object Pool

All selected objects are shown in object pool.

Select Object Randomly	Spawn object randomly or sequentially.
Order	Custom order when using sequential, fill with the index with comma. You can use -1 to skip one step.
Slider	The weight of the object when choose randomly.
Three Dots	Press it to override object randomness.

Randomness

There are three randomness settings for grid mode, surface mode and scatter mode.

Global Hotkeys

Enter / Left Click	Place object.
Esc / Right Click	Exit Level Builder.
Space	Reselect object.
R	Reset offset / rotation / scale.
N	Use new randomness to spawn objects.
Mouse Wheel	Reselect object randomly or next object for sequential.
P	Hold P to select custom pivot point. Alt P to restore original pivot point. Shift P to apply custom pivot point to all object pool objects.
\	Hold \ to suspend Level Builder ui. You can change camera location and angle.

Custom Pivot Point

When selecting custom pivot point, you can use mouse wheel to change different selection mode. 1) edge / face center of the bounds. 2) project original pivot point to bounds. 3) same as 1 but exclude (0,0,0) in bounds. 4) same as 2 but exclude (0,0,0) in bounds.
