I’ve got the blender source, I’ve visited and I’ve read everything on that website but I still don’t know who to modify the code.

Can anyone help me???

what are you trying to do?

And most important of all, even though it might be a silly question. Are your skills with C/C++ any good? Ever done anything with it before?
I haven’t tried modifying the blender source myself but any application this complex can’t be easy to program without the right knowledge (and time, it’s always about time when you’re in front of a computer xD).

If you are actually quite competent with C and C++ just disregard this ^^
