Hey man, I was testing a new mod out called Zombie plague2 for 1.7.10 and noticed that your skinport mod doesn't let this mod do its swimming or holding gun animation. I was wondering if this could be fixed? or edited so it can be a little bit compatible with this mod?

That is to be expected as SkinPort replaces the player model, it would require specific patches for mods with player animations to be compatible.
I don't really do these compatibilities though, sorry.
If you know how to code or have someone who can do it for you, you are welcome to fork the code to make it compatible, as SkinPort is licensed under MIT License.

ok thanks for your help and I will just deal with the animation issue. Thanks again for the advice and will use it in the future
