XML TRSC << Other file types >> TXMB switch to OBD page

general information

• The xml code on this page is compatible with onisplit v0.9.61.0 and 0.9.68.0
• TURR file are stored globally (in AE/AEInstaller/vanilla/level0_Final.dat)
• M3GM <BaseGeometry> isn't used, the turret pod is part of the AKEV level geometry

embedded M3GM

new export method

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

onisplit -extract:xml output_folder input_folder\TURRfile.oni

old export method

You would need to cut TURR instance so that only the M3GM and its connected instances remain and convert it to oni.

onisplit -extract:xml output_folder input_folder\TURRfile.oni

onisplit -create output_folder input_folder\cutfile.xml

version hint:

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

new import method

There's a bug in OniSplit. Before you can re-convert dae and xml to oni, you must clean some tags in the xml file.

For example TURRvdg_turret_wall.xml

<ParticleCount>4</ParticleCount>

That means 4 <ParticleClass> are used, the others are not.

They contain garbage like <ParticleClass>�ޭޭޭޭޭޭޭ�</ParticleClass>. Remove that content, make it: <ParticleClass></ParticleClass>.

Then you can re-convert.

old import method

Are there some tags which make together the mesh but you basically need to know that you can replace that content with data from another M3GM.

You can 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.
