the tutorials can very quickly get outdated due to the fact
- if you use the MH nightly builds which can break or add things
- Blender gets updated , can add issues with fbx exporting
- UE4 gets updated/hotfix can cause issues when importing blender fbx files !!!
trust me it annoys the hell out of me after doing hours of tests and working out who/whats at fault and working out how to get round them. my answer is if its not broke why fix it , but the bottom line is that there are issues from all 3 programms and the devs don’t work together.
just post a tread or pm/email the people that posted the tutorials, you’ll actually find some people who are willing to help you along
