What is the exact error?
Did you rename your armature to Armature?
Did you use the Game Engine skeleton and not one of the others?

I didn't know what armature was, but I figured it out.

I'm glad that the problem was solved.

You need to rename the armature object to "Armature". Problems may occur if you import characters into additional scenes that are not the default scenes. Post the modified script. Thanking for pointing that out.

[MrGoatsy]

I got most animations to work fine, however a few like rolling don't work.

This is how it is supposed to look:
https://i.imgur.com/NB71nej.gifv

This is how it looks with the mesh:
https://i.imgur.com/JCMirR6.gifv
https://drive.google.com/file/d/1EiJzwl ... p=drivesdk

In both images they use the same skeleton.

All other animations pretty much look exactly the same except climbing a ladder which is also messed up, I assume once I fix the rolling the ladder animation will also be fixed.

How do I fix this?

[MrGoatsy]

Sadly i have been unable to find a solution to the 'anchor' problem. Many, Many attempts. including or not including body parts, hair, etc. nothing is fixing it.
Perhaps the code that is posted on this page is slightly different than what you have locally on your computer?
Maybe you could post the script again, just to make sure.

Thank you

I used the script from this page.

It is weird though, most animations are fine, only a few are messed up.

Are you talking about ALS rolling? In the ALS description section of the epic marketplace, it says:
---
IMPORTANT: IT IS HIGHLY ADVISED THAT YOU HAVE A GOOD UNDERSTANDING OF BLUEPRINTS AND ARE FAMILIAR WITH HOW GAME ANIMATION WORKS PRIOR TO YOUR PURCHASE OF THIS PACK. THIS IS NOT A PLUG AND PLAY SYSTEM, AND WORKING WITH IT CAN BE CONFUSING IF YOU ARE NEW TO UE4.
---
Also personally, I'm using Unreal Engine 4.23 and the ALS version is 3.I will do additional research, but it may take some time.

The problem was solved more easily than I expected. I was able to solve it by rotating the Root bone.

This also fixed it, however when I put armour on my character the lower arm part gets messed up, when I use the other method I used previously it doesn't warp the lower arm part.

Q1: If I export a naked character, does it work fine by replacing it with a third person template character or an ALS4 character?

Q2: What is "armour"? Is it a make-human asset?

Q3: What is the "other method"?

I exported a character wearing long-sleeved clothes and replaced it with a third person template character or ALS4 character, but it seems that there is no particular problem.
