will the bp files match 4.7 version?
There is a few lighting model changes as to translucency between 4.6 and 4.8 that is making a lot of the reflections flat.
This is top notch! With this same quality, I’d like to see a modular gun system. A blueprint with drop down menus that can be used to switch out parts of the gun.
It wouldn’t even have to use parts modeled after a real life gun, just parts that allow you to make a variety of guns.
Just a thought for a future product. 
Thank you! We are making a new pack which will probably contins all what you suggest.
Mmmmm…, that’s unpredictable. We will make next pack compatible with this.
Sorry, since there are many changes with c++ code in every recent version of UE4, which foundementally affect BP, we can not keep updating BP files.
Even we make BPs compatible with 4.7, there will be 4.8, 4.9…
Therefore, in next pack, we will make all functions built with pure BPs. But still, it is possible that those BPs are imcompatible with some future versions of UE4. Only Epic knows 
can I noe how does the screen capture on the scope when not zooming work?
Is there a blueprint weapon preview in 4.8 on either Shooter Game or Generic Shooter ?
why I have infinite bullets?
how i can change this?
