Hello!

I'm trying to port a map from blender eevee and how do port mats from cycles to blender internal?

Every time i try to install the source tool addon it always says: Traceback (most recent call last):
File "C:\Program Files\Blender Foundation\Blender\2.79\scripts\modules\addon_utils.py", line 331, in enable

File "C:\Users\User\Appdata\Roaming\Blender Foundation\Blender\2.79\scripts\addonsio_scene_valvesource\_inet_.py", line 60 ob_type : StringProperty()
^
SyntaxError: invalid syntax.

And i do not know what to do? Can anyone help me?
