Installing Python For Blender Users.

[jay pettitt]

Those of us using Blender to produce models for export to Doom3 Radiant will at some point need to install the Python programming language for the various plugin scripts that enable Blender to export to the file formats supported by Radiant. The process is not as streight forward as it could be, so here I am detailing the procedure for Windows users.

 

 

Updating Blender

Make sure you are running Blender 2.35 or later.

 

 

Downloading and installing Python

Download Python and run the setup program. Ensure that the destination directory for the install is the default: C:/Python23

 

 

Setting a System Variable for Python in Windows XP, 2000, NT

For Python to work correctly with other software (such as blender) a system variable must be set. Open the Control Panel (in classic rather than catagory view for XP users) and open the System properties dialogue box. Select the Adavanced tab and press the Environment Variables button.

 

Scroll through the list for System Variables and look for one called PYTHONPATH. If on does not exist you will need to create a new System Variable, otherwise you can edit the existing variable, by pressing the appropriate button.

 

In the System Variable dialogue box enter:

PYTHONPATH in the Variable Name text field and C:\Python23\lib;C:\Python23\;C:\Python23\DLLs;C:\Python23\tcl;C:\Python23\libs\ in the Variable Value text field.

 

 

Setting a System Variable for Python in Windows 9x

In notepad load the text file C:/autoexec.bat

Add the following line:

SET PYTHONPATH=C:\Python23\lib;C:\Python23\;C:\Python23\DLLs;C:\Python23\tcl;C:\Python23\libs\

(thats all one line by the way, without any line breaks that might appear in your browser)

Save, reboot and off you go
