General information

• The XML on this page is compatible with OniSplit v0.9.61.0 and 0.9.68.0.
• TURR files are stored globally in level0_Final.dat.
• TURR instances for a level are stored in BINACJBOTurret.
• The M3GM in <BaseGeometry> isn't used; instead the turret body is part of the AKEV level geometry.

File structure

Vanilla classes

3D model

Export (new method)

With OniSplit v0.9.94.0+ (and possibly a few older versions), you can extract the DAE together with the XML from the .oni.

onisplit -extract:xml output_folder input_folder\TURRfile.oni

Export (old method)

You would need to trim the TURR instance so that only the M3GM and its connected instances remain, and save that as a .oni file.

onisplit -extract:xml output_folder input_folder\TURRfile.oni

onisplit -create output_folder input_folder\cutfile.xml

Version advice:

OniSplit v0.9.61.0 and v0.9.68.0 can extract M3GM only as OBJ.

OniSplit v0.9.41.0 can extract M3GM as OBJ or DAE.

Convert the M3GMfile.oni to OBJ:

onisplit -extract:obj output_folder input_folder\M3GMfile.oni

Import (new method)

There's a bug in OniSplit: before you can convert the DAE and XML back into a .oni, you must clean up some tags in the XML file.

For example, looking at TURRvdg_turret_wall.xml…

<ParticleCount>4</ParticleCount>

…that means 4 <ParticleClass> are used and the rest are not. However, those unused elements contain garbage like "<ParticleClass>�ޭޭޭޭޭޭޭ�</ParticleClass>". Remove that content, making it "<ParticleClass></ParticleClass>". Then you can re-import.

Import (old method)

You can replace the M3GM content with data from another M3GM.

You first create M3GM meshes from OBJ files.

onisplit -create:m3gm output_folder -tex:weapon_tex input_folder/weapon.obj

-tex is optional

The TXMP file must created separately (if needed).

Then you can convert the file to XML and replace the TURR's old M3GM XML code. Remember to change the links (#N) and instance IDs of the new data.
