Where are the modifier scripts in the Blender package contents folder? I need to find where Blender has applied their modifiers and physics scripts within their program so that I can install and place my own that I have. Either it has been a very long day already or I am simply blind because I have looked through every file and every option available for several hours now and am about to go crazy. If someone has a file path or can send a screenshot of where it is it would be much appreciated.
Blender's modifiers and physics related routines are written in C/C++, you won't find them in the scripts directory. Download Blender's source here as an archive or use GIT
