just a few notes on exporting, we should make a proper tutorial someday
- install OgreBlenderExport_v1.4.0_prefixpatch :
- download http://ghoulsblade.schattenkind.net/ogre/OgreBlenderExport_v1.4.0_prefixpatch.zip
- (this is a modified version i made to automatically prefix all material names and filenames with something to avoid conflicts with other models)
- unpack and move the everything inside (also subfolders) it into
- (win:) YOUR_BLENDER_DIR/.blender/scripts
- (linux:) YOURHOME/.blender/scripts
- install python
- for win : http://python.org/download/ : Python 2.5.1 Windows installer
- for linux : "apt-get install python" or something like that
- install OgreXMLConverter :
- for win : OgreCommandLineTools_v1.4.0.msi
- for linux : OgreXMLConverter is included in the ogre package or the ogre source
- open the .blend file you want to export (e.g. double click the .blend file)
- select the object you want to export using rightclick
- (you can only export single objects, but you can make multiple subobjects somehow)
- open the "script-window"
- rightclick the seperator between the 3d-view and the bottom panel and select split area
- on the left button of the new panel select "script-window"
- next to it a "scripts" button appears, select "Scripts":"Export":"OGRE Meshes" there
- enter a unique prefix for you model and materials in the line saying "Prefix all names with this :"
- (avoid spaces and special letters, something like ke_gpl_biotube_ is good)
- the broad "copy texture" button should be active/pressed
- select a directory where to export
- creates multiple files, .material and .mesh file, and texture images are also copied
- i suggest using a new empty directory
- the "OgreXMLConverter" button should be active/pressed so we get a .mesh instead of a .xml
- hit export
- if you only got a .mesh.xml file, but no .mesh file, then the exporter couldn't locate the path to the OgreXMLConverter
- to fix this, click "Preferences"
- in "OgreXMLConverter Location" : click "Manual"
- on win : select the path to the OgreXMLConverter.exe , e.g. C:\OgreCommandLineTools\OgreXmlConverter.exe
- if you can't find it you need to install OgreCommandLineTools_v1.4.0.msi , see above
- the model will probably have to be rescaled, recentered and rotated
- we created a specialized editor for that, see HowToAdjustMeshesForSFZ
- one object ingame is one object in blender, so you have to combine multiple parts to a single object to export it
- this can be done with ctrl + j : combine objects
- texture images should have a size that is a power of two, e.g. 32,64,128,256,512,1024,...
- don't make textures too large to save video ram ingame, 256x256 should be enough for most things, but please keep a backup of the original high-res texture
- most blender texture effects and shaders will not work ingame, a plain texture is the easiest to get to work
- on the lowest panel, select "buttons window" on the menu on the left.
- if you want to edit object and mesh names : on the "Panels" menu select "Editing" : "Link and Materials" panel
- if you want to edit material names : on the "Panels" menu select "Shading":"Material"
- if you want to edit texture names and image paths : on the "Panels" menu select "Shading":"Texture"
- transform window : press n
- lower right of the transform window should be near 1,1,1 for one ingame tile (press s to scale the model)
