How to assign/use ue4's default skeleton for my character?

i have made a character with skeleton and so on , and i want to use use ue4’s skeleton asset and animation for my character , does anyone have an idea how to do so ?
i have followed a tutorial but it didn’t work , i had several errors something like 'can’t merge ’

Hey there, if your rig has exactly the same bone structure as the UE 4 Skeleton you can do the following:

  1. Import the fbx
  2. Make sure skeletal mesh and import mesh options are ticked
  3. On the skeleton make sure you pick ue 4 skeleton asset.

If your rigged correctly you should be able to assign your character’s mesh with the same skeleton and play the animations that were imported for that skeleton.

no i didn’t use the exact bone structure , because im using blender and i used blender’s rigify tool to make a skeleton ,
and for now i would love to know how to use ue4 bone structure , because i tried to export the skeleton mesh from ue4 but it saved it as .COPY file
so any idea how to use ue4 bone structure with my custom character ?

If your skeleton doesn’t have the same bone structure as the ue 4 skeleton then either you change your bone structure or you have to retarget the ue 4 skeleton animations to your skeleton. You can find more about retargeting here.

, well for now i found a good tutorial , i followed it but the only problem i had was that if i go to the existing animation , right click , and then chose duplicate animation and retarget the animation duplicates but the animations were all dark , and when i applied it (according to the tutorial ) it showed like dark and some movement , cant really tell what is it

I see that you have opened a separate issue for this, so please mark the answer as correct to close it.
