If your programmer must have other people on forums find hacks for him, and does not have the skills to read through the source code and find the answer himself, then perhaps you need to skill him up?
When I ask a question in the Unreal Forums, and sometimes don’t get an answer (because my questions are often not on the mainline path,) I’ve always managed to find the area of the engine that implements the feature in quesiton, and read through it and understand what’s going on.
That being said, if your programmer isn’t great at C++, then Unreal may not be a great fit for him/her.
