Import-Export

Menu:

File ‣ Import/Export ‣ Stanford (.ply)

Use the operator to import ASCII or binary PLY-files, you can select multiple files at once. For exporting, you can choose to enable or disable the modifiers during the export and you can choose which data you want to export (UV textures, Color Attributes, …).

Import

Scale

Value by which to scale the imported objects in relation to the world’s origin.

Scene Unit

Apply current scene’s unit (as defined by unit scale) to imported data.

Forward Axis, Up Axis

Since many applications use a different axis for ’Up’, these are axis conversion for these settings, Forward and Up axes – By mapping these to different axes you can convert rotations between applications default up and forward axes.

Blender uses Y Forward, Z Up (since the front view looks along the +Y direction). For example, it’s common for applications to use Y as the up axis, in that case -Z Forward, Y Up is needed.

Merge Vertices

Attempts to combine co-located vertices where possible.

Import Vertex Colors

The color space that the color data in the ply-file was saved in.

None:

Does not import vertex color data.

sRGB:

Vertex colors in the file are in sRGB Color Space

Linear:

Vertex colors in the file are in Linear Color Space

Export

Format: ASCII

Formats the file using the simple a ASCII format. This option might be helpful if the program that will later import the file does not support the binary file format.

Limit to: Selected Only

Only selected objects are exported. Instanced objects, for example collections that are instanced in the scene, are considered ’selected’ when their instancer is selected.

Scale

Value by which to scale the exported objects in relation to the world’s origin.

Forward Axis, Up Axis

Since many applications use a different axis for ’Up’, these are axis conversion for these settings, Forward and Up axes – By mapping these to different axes you can convert rotations between applications default up and forward axes.

Blender uses Y Forward, Z Up (since the front view looks along the +Y direction). For example, it’s common for applications to use Y as the up axis, in that case -Z Forward, Y Up is needed.

Objects: Apply Modifiers

Export objects using the evaluated mesh, meaning the resulting mesh after all Modifiers have been calculated.

Geometry: UV Coordinates

Write out the active UV layers coordinates from Blender.

Geometry: Normals

Write out Blender’s face and vertex normals (depending on the faces smooth setting).

Mostly this isn’t needed since most applications will calculate their own normals but to match Blender’s normal map textures you will need to write these too.

Import Vertex Colors

The color space that the color data in the ply-file was saved in.

None:

Does not import vertex color data.

sRGB:

Vertex colors in the file are in sRGB Color Space

Linear:

Vertex colors in the file are in Linear Color Space

Triangulated Mesh

All N-gons with four or more vertices will be triangulated. Meshes in the scene will not be affected. Behaves like Triangulate Modifier with the following settings:

• N-gon-method: «Beauty»

• Quad-method: «Shortest Diagonal»

• Min vertices: 4
