So I have been tinkering around with a couple versions of the flans mod engine for 1.7.10 and I've come across some issues. One engine, will render the guns from a specific content pack as they should be rendered, while if I use the other engine they won't render at all. So I was wondering what the difference was with the files in them. For what I'm doing, I need to use the engine that isn't rendering said guns correctly, and I was hoping someone could tell me which class files to move over to said engine if it's that simple. However, if it isn't, I'm more than willing to open the class files in eclipse and try to understand how they differ and try to either edit or combine them somehow. Any help you guys can give me would be greatly appreciated!
(Also, sorry if that's a mess to read and understand, I wasn't quite sure how to convey my question)
