MeshImport

In This Article:

MeshImport is a tool for converting formats of geometry and animation data.

MeshImport tool is used:

  • To convert meshes of external formats to Unigine-supported mesh formats.
  • To upgrade the Unigine-based project meshes, which are outdated, to the up-to-date mesh formats.

You can use the Unigine upgrade script for batch upgrading of the outdated meshes.

Usage

To invoke MeshImport, run meshimport_x86.exe (in Windows) or meshimport_x86 (in Linux) from the command line (the Windows command prompt and the Linux Terminal) (the 64-bit version has x64 postfix).

  • Under Windows, type at the command prompt:
    Shell commands
    meshimport_x86.exe OPTIONS FILE
  • Under Linux, type into the Terminal:
    Shell commands
    meshimport_x86 OPTIONS FILE

Command-Line Options

MeshImport recognizes the following command-line options:

  • -o NAME — name of the output file.
    Notice
    If the -o option is not specified, the default .mesh extension is used.
  • -s SCALE — scale a mesh. The default is1.0, no scaling. The option value is float.
  • -tx VALUE — translate a mesh along theX axis. The option value is a float number.
  • -ty VALUE — translate a mesh along theY axis. The option value is a float number.
  • -tz VALUE — translate a mesh along theZ axis. The option value is a float number.
  • -f — flip the Y and Z mesh axes.

Input Data Formats

The following formats of geometry and animation data can be converted by MeshImport:

  • Wavefront (.obj)
  • COLLADA (.dae)
  • FBX (.fbx)
  • Unigine mesh (.mesh)

Output Data Formats

The following output formats are supported:

  • Unigine mesh (.mesh)
  • Wavefront (.obj)

Examples

Convert an External Mesh

Let's suppose that you want to convert a mesh called mesh.obj to the Unigine-supported data format. If it is located, for example, in the D:\my_project\external_meshes folder, you need to invoke MeshImport as follows:

Shell commands
meshimport_x86.exe "D:\my_project\external_meshes\mesh.obj"
The external mesh file is converted to the Unigine-supported mesh format file with the same name:
Output
D:\my_project\external_meshes\mesh.obj -> D:\my_project\external_meshes\mesh.mesh
Notice
The tool supports batch files conversion. You can specify a list of files to convert them at once. But if you use the -o option, you can specify only one file to convert.
For example, to convert my_mesh1.obj and my_mesh2.obj use the following:
Shell commands
meshimport_x86.exe "D:\my_project\meshes\my_mesh1.obj" "D:\my_project\meshes\my_mesh2.obj"

Upgrade an Outdated Mesh

Assuming that you need to upgrade the Unigine outdated mesh called my_mesh.mesh to the up-to-date mesh format. For example, if the file is located in the D:\my_project\meshes folder, then you need to invoke MeshImport as follows:

Shell commands
meshimport_x86.exe "D:\my_project\meshes\my_mesh.mesh"
Now, my_mesh.mesh file is upgraded.
Notice
The tool supports batch upgrade of mesh files. You can specify a list of files to upgrade them at once. But if you use the -o option, you can specify only one file to upgrade.
For example, to upgrade my_mesh1.mesh and my_mesh2.mesh use the following:
Shell commands
meshimport_x86.exe "D:\my_project\meshes\my_mesh1.mesh" "D:\my_project\meshes\my_mesh2.mesh"
