I just downloaded blender 2.70 windows 64. I want to convert .obj files to .X files to use then in the pmd editor and MMD. I cant find an export to .x file. the tutorial that I am looking at is for an older version of Blender.
Enabling Import & Export of DirectX 3D Model file format .X
Blender 2.70 comes with the "DirectX X Format" Export addon built-in.
However, the "DirectX Importer" Import addon is not built-in. If you'd like to have the ability to import .X files, you can download it in this addon bundle. (Note: that post describes how to add the addon to Blender's scripts folder.)
To enable these:
Info header -> File -> User Preferences
Then, in the search box, type Direct. Two DirectX addons will appear:
The one named "DirectX Importer" provides the ability to Import .X files
The one named "DirectX X Format" provides the ability to Export .X files
Check the checkbox at the right hand side of the addon to enable it
If you want to always have these import/export options in your File menu, then click on the Save User Settings button at the bottom of the screen:
You will then have the .X file format as import & export options:
