Hey guys, I am just finishing up a big update for the package which will include more modular road parts, a comprehensive breakdown (video & documentation), as well as a bunch of other improvements, bug fixes, few new assets and blueprint updates. The biggest thing is adding all the fbx files for further customization. I excluded these originally to keep package size down, but from the sounds of it, people want to export these assets into their 3d software and customize them accordingly.
I am just wrapping everything up today/tomorrow and hopefully get this update in some time this week. Sorry for the issues. In the future, please email , as I am much more likely to respond to that faster than this thread. But I think this update will fix all the problems your having.
