Shotty, its nice to see you have some passion, however, I do think that you are misdirecting your frustration. KVogler was not offending you in any way, he was merely advising you that Unreal Engine 4’s bsp system is not up to the task of complex brushwork. It is one of a few areas of the engine that Epic have not spent as much time on compared to the rest of the engine. I believe Epic would love to refocus their attention on bsp, however most of the company are working on multiple game projects. Please be patient until Epic finds the time to introduce geometry 2.0, or wait for the Probuilder plugin when it arrives. Also, while you wait for these engine updates, you can download Blender for free. I, myself have been using Blender in my personal projects and find it to be just as good, if not better than some of the commercial 3d modeling options, which I have plenty of experience with.
I get frustrated all the time when my game design experiments do not turn out the way I would hope, but I think you should remind yourself that most of the Unreal Engine community are in the same position.
