When starting up the echo windwalker character from unreal marketplace, the character has no hair and the hair groom blueprint is broken. There were errors on the hair and eyebrow grooms but this seems to have been fixed by converting them to local variables. Though I can’t seem to connect the groom assets to the rest of the blueprint. I’ve tried re-downloading the character multiple times but this issue remains, no idea how to fix this.

I also have that problem, I noticed that some assets were not correctly loaded, I also tried to download the project multiple times but no success, I think there is a bug in that package. If you find out a solution let me know please :3
Did you find any solution to this yet?
All hair assets seems to be broken.
Right click the .uproject and open the file in a text editor. In “Plugins” : add the following:
{
"Name": "HairStrands",
"Enabled": true
},
{
"Name": "AlembicHairImporter",
"Enabled": true
},
Alternatively you can enable the plugins through the Plugins panel

DID YOU TRY TO ’ CTRL + LEFT MOUSE BUTTON DOWN ’ ON THOSE RED CONNECTION PINS?
AND THEN RECONNECT THEM?
RIGHT CLICK ANY NODE TO SELECT ’ REFRESH … ’
Is there a solution for this, for UE 5.4? I’ve turned on all the right plugins and still can’t seem to get her hair loaded for the Control Rig. Thanks in advance 
Open it with a 5.2 version or lower enabling the plugins. Then migrate the BP_Echo blueprint (right mouse button → Assert Actions → Migrate) to a 5.4 version with the same plugins enabled. It worked for me.
For 5.4.2 this worked for me: In the groom asset set LOD Mode to Manual and set Curve Decimation and Vertex Decimation to 1.0
Let me know if it helped
ETA:
I’ve kept on trying different things and in the end decided to download UE 4.27. There the character WAS correct. I upgraded (via making a copy) the project to UE 5.2 and now the hair is perfectly normal. Problem solved!
Previous answer:
Opening this project in 5.2 already gives all the errors, so migrating the blueprint to 5.4 seems useless. I’ve installed the missing plugin, I’ve tried @axl_man’s suggestion for 5.4.2, but that unfortunately didn’t help in 5.2
I’ve tried finding the correct connections, but I have no clue what to look for.
Refreshing the nodes doesn’t seem to do a thing either as that seems to give me an empty node (It’s probably because I don’t quite understand how it works)
I’m just a newbie trying out things. I was hoping to use this character in a future project of mine.
These are the errors I get:

Thank you so much for the help!
