just a few notes on exporting, we should make a proper tutorial someday

guide

• first you need to install the blender ogre exported :
  • download Blender Exporter v1.4.0
  • unpack and move the everything inside it into (win:)YOUR_BLENDER_DIR/.blender/scripts or (linux:) YOURHOME/.blender/scripts.
  • start blender
  • 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, you can find the exporter under "Export":"OGRE Meshes"
  • this just exports to meshes from Blender to Ogre XML
  • you need OgreXMLConverter contained in the OgreCommandLineTools_v1.4.0.msi to turn the XML (item.mesh.xml) into a runtime binary mesh (item.mesh).
    • set the path to the OgreCommandLineTools folder in the blender mesh exported window under preferences : click manual
  • you also need to get a full python installation ( http://python.org )

• open the .blend file you want to export (or close blender and start it by double clicking 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)
• on the lowest panel, select "buttons window" on the menu on the left.
• on the "Panels" menu next to it select "Object"
• set a unique object name in the panel on the lower left (avoid spaces and special letters, something like ke_gpl_biotube01 is good)
• on the "Panels" menu select "Editing"
• in the "Link and Materials" panel, change the name to somethimg meaningful, like ke_gpl_biotube01

• on the "Panels" menu select "Shading":"Material"
• on the second subtab, "Links and Pipeline", edit the name of every material to start with something unique for this model, like "ke_biotube_mat0", to avoid conflicts with materials of other models

• if you have renamed some texture files :
  • on the "Panels" menu select "Shading":"Texture"
  • correct the imagepath of every texture using images

• rename all texture filenames to be prefixed with something unique for the model, e.g. ke_gpl_biotube01_tex.png
  • adjust file path references in the blender model

• export :
  • in the script view panel, select "Scripts":"Export":"OGRE Meshes"
  • change "Material File: Scene.material" to a better filename, like ke_gpl_biotube01.material
  • the broad "copy texture" button should be active/pressed
  • select a directory where to export (.material and .mesh file, and materials are also copied, i suggest an 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, see OgreCommandLineTools_v1.4.0.msi above.

• the model will probably have to be rescaled, recentered and rotated ... see below

• see HowToTestModelsIngame

old notes

resizing, rotating and recentering has to be done in blender until we find the time to implement an editor for something like this in sfz.

• press n : transform window,
  • set pos to 0
  • lower right of the transform window should be near 1,1,1 for one ingame tile (press s to scale the model)
• move the middlepoint to a position on the grid
• go to edit mode and move the mesh so that it is aligned to a unit-sized grid

• this forum thread in iris2 about exporting ogre models might also be interesting : http://www.iris2.de/forums/viewtopic.php?t=1061
