Hey, have you read the Epic’s guide to retarget anims form the mannequin to the metahuman skeleton?
Epic’s guide for the Metahuman from the Marketplace
Epic’s guide for the Metahuman from the Metahuman Creator
I have just retargeted my idle M4 anim to the metahuman from the Marketplace (of course, deleting the virtual bones form my skeleton first, as I explained here **- EDIT: With the new update you no longer need to delete and re-add virtual bones! Please let your Epic Launcher download the new update). Please tell me if you’re able to retarget after reading the Epic’s guides. If not, tomorrow I’ll record a video of me doing the retargeting.
Also remember that when it comes to retargeting, hands position on the weapon are never supposed to be exactly as original, because different skeletons have different bone sizes. It’s usually ok for 3rd person games, but for 1st person games you’ll probably need to adjust your final result (or use anims made specifically for that character).
