4. Exporting Importing

(WIP)

Exporting

1. Select the VF_Volume_X object you want to export (the floating points)
2. Use UE4 Vector Field (.fga) in the export menu
3. There are two sets of options for exporting:

Export Options:

Method 1: Use settings from editor/object (Default)

• Use this method to export the vector field using its current shape and location in the scene.

Export Scale

• a multiplier for the size of the vector field in UE4.
• The actual size in UE4 will be: Bounds Scale x (the vector field's resolution) cm^3
• defaults to 100, making a default scaled 16^3 vector field into a 16m^3 volume in UE4

Scale Velocity

• scale the velocity with bounds scale during export

Export Location Offsets

• Allow the vector field's location in the scene to affect the exported bounding volume
• This only works with Location trnasforms that have not been applied.

Method 2: Manual Bounds (Advanced)

• Use this method if you want to manually define the bounding box and velocity scale of the exported file.

Enabling manual bounds will remove the above options and replace them with:

Minimum, Maximum

• Bounds in cm
• manually set the values for the vector field's bounding box.
• min should always be less than max

Scale Velocity

• Multiplier for velocity

Importing

• Use UE4 Vector Field (.fga) in the import menu

#####Import Options:

Import Scale

• Scale to apply to the file's bounds
• Used to shrink UE4 volumes to a more easily manageable size in Blender

Scale Velocity

• Scale the velocities during import

Get Offset

• Calculate and import the offset of the volume's bounds from the file
