3:40 you can set visible=off and then scroll a little down to "optimization" and "advanced" and set "Visibility based anim tick option" to "Always tick pose and refresh bones" so the animations work even when the parent's visibility is set off!
If you want your metahuman to do the retarget live when als mesh is hidden you have to set the skeleton mesh to always tick and refresh bones, by default it will be only when rendered.
Thanks for the tutorial! I'm having some glitches in ragdoll though... I have tried 3 more tutorials and it was the same outcome in all, ALS character that we hid at the end doesnt perform the same issue if we set it visible and scope both at the same time....
Many thanks for putting this together! I just wanted to mention that I've found that including the Face component as a Target for the Set Leader Pose Component (3:20) seems to prevent the face control board from working properly in Sequencer and prevents facial animations from being played back in general. Disconnecting it appears to correct the problem. Has anyone else experienced this? Should I expect any side-effects?
Unreal now has an option to hide the original ALS mesh. Around 3:28 just select the ALS mesh, go into Details and search Visib... or look under Rendering > Visible. I copied over my metahuman and the head separated from the body, but I think I just got unlucky with the metahuman I chose.
Hi there! I can't make my character do any animations while playing, even if the ALS animations work fine in the Retargeter I can't understand why is that, can someone help me? Thank you
Please help, I did everything as you indicated, but when starting the game, it still starts as a standard blue character, and my metahuman just stands on the map where I placed it and turns towards the standard character. I tried to set the default character to metahuman in gamenstas, but it doesn't help. What should I do so that the game starts with the new blue print that we created and not with the standard one?
Take it out. See if it breaks. It likely will, as it is the parent of the Metahuman but it might be worth playing with. With the mesh not visible, there wouldn't be any graphic overhead anyway.
Hey, great tutorial! This aaaalmost works for me, but the hands are unfortunately messed up, both for climbing and holding weapons. The gun floats off to the right and even after playing around with the scale, it doesn't seem to work well with hanging on ledges etc. Any idea how to fix this?
By the sounds of it, you may need to update the virtual bones / bone names in use to use your skeletons bones / virtual bones and not the original. Using this approach, that original skeleton still exists, your new skeleton is just copying it. So you need to find in the code where those bone names are being called and direct them to your new skeleton :)
I would recommend deleting the metacarpal bone chains to not get auto mapped chains, which will mess up the hands. Additionally I assume this will not fix the overlay states right? The ik bones and virtual bones get messed up.
The overlay states still work as intended but it should be noted that they'd be using the original meshes transforms .etc anyway so they'll be offset. You can go into the overlay state code itself (exposed and implemented in Blueprint) to adjust the target to the new mesh.
When you say hand placement - I assume you mean the actual hand placements in animations using this method? If so, as we're emulating the position of the original via this method, the original (as seen in the video) has longer arms which explains why arms aren't reaching to the destination. If that IS what you mean, you could use a Control Rig (or IK nodes) after the "Retarget Pose From Mesh" in the AnimBP to adjust the emulated animation to move the shoulders or arms forward a little to compensate for the shorter arms.
My question is how do you even get the project to run in Ue5.1? I've followed the wiki, and I'm not going to lie. This is not beginner friendly. I have essentially no c++ experience. I know basics of installing visual studios, but that's it. And there aren't any tutorials that will even walk you through the steps of doing this. Would be nice if people would actually explain this a bit better.
@@KITATUS Yes please, that would be amazing. I am on the github page and have no clue how to install the plugin. If you could make a full beginner friendly tutorial from start to finish?
Original is a marketplace Blueprint project, Community version is a C++ version of that blueprint project aimed at improving performance and fixing bugs. The community version is made and maintained by the community and not the original creator.
It's a bit more tedious but should be possible. Once you've got the IK rigs, retarget the main Anim Blueprint (which should auto retarget the children) and try and recreate any references elsewhere. You'll have to adjust curves and whatnot that depend on the original mesh though.
I would wait an official 5.1 version but if you can't wait, edit the .uplugin file with your text editor and change engine version to empty instead of "5.0.0" - ensure the project this plugin is installed to has any c++ in it so it can force recompile the plugin.
Yet another 'tutorial' that doesn't explain anything, doesn't mention the extra performance cost of live retargeting. No mention of the overlays or the items, because they don't work.
The written version of this guide (available in the description) mentions that on the performance front, I have only anecdotal notes from doing this that in my personal use-case there was no significant performance impact but that your mileage may vary. If you would like a deeper dive into performance costs, I can happily look into it for you. Overlays should work out of the box - the issues you're having with items (without seeing your project) is that they're being attached to the hidden rig and not your MetaHuman. You can fix this by overriding the OnStateChanged and replacing the reference to the old mesh to your MetaHuman. If there is any system or feature or step about this you'd like a deeper dive into to understand the systems more, I'm happy to put a guide together. Thanks for the feedback!
@@KITATUS There is a relatively significant performance cost for 'live' retargeting. Somewhere around .01-.1ms added to frame render time per instance iirc. Which makes the less than ideal in many situations. The constraint bones (e.g. IK and virtual) are not converted by the retargeter currently. So even if the item appears to be close to the socket, it will be out of place. This is only fixed by editing the animations. Additionally, the skeleton retargeting options should help with skeletons of different proportions (looking at your other comment).
@@ostrava_ .01-.1 is a massive variation, at some point I can look into specific numbers and possible ways to get more consistent results if that is content you're interested in. The IK bones can technically be accounted for via the retargeter iirc (atm most people don't use it, they chain map the same IK bone to itself but technically it should be possible from root?) but that still leaves the virtual bone issue - Technically some of these can be altered in the blueprint itself but not all of them. I believe over time the IK Retargeter will get better (we've already seen massive improvements) but Advanced Locomotion itself is not intended to be a basis but an inspiration for the start of your own movement system - thus I think if performance were an imperative metric that an alternative solution should be found; be that from baking out the animations via the IK Retargeter or by making a system from scratch.
@@KITATUS .1ms is the quoted value, but it would be machine specific to some extent. In my experience the retargeter doesn't correctly handle the IK bone positions, e.g. even in your example they aren't translated at all to the new animation. You can set up a 'Constraint Solver' in the retargeter to handle this. This will also constrain the VB to the correct bone, assuming you know which bone to constrain it too. I have only actually fixed hand placement issues by editing the animations in control rig or sequencer, but I think there is a tool from Tuatec that automates this. Yeah, it seems to be part of the larger effort by epic to add first class animation support in engine, or near enough. I don't really agree with the last bit. As even the original ALS is described as a good starting point. adding on the optimizations with the community version, and then even further optimization in the ALS Refactored version. It still isn't the most performant system, but that is the trade-off for the complexity of the animation system. Performance is always going to be a relative metric. But yes 'offline retargeting' as epic calls it, e.g. duplicating & retargeting the animation assets, is the optimal way.
The Metahuman Creator from Unreal is useless. There are only the pre sets. How can I make a new face in UE 5.1? The Metahuman Plugin is not available for UE 5.1. Let's say I want to build my face. How do I do that?

Once I set visibility to off, it was no more working. So I got to go back to transparent material.
@@koko-nl5tp you have to enable anothee option after that for it to work when it's not visible, it's in my comment too

for some reason torso and shorts of my character are not animating as the rest of the body and feet
Hi there! I can't make my character do any animations while playing, even if the ALS animations work fine in the Retargeter
I can't understand why is that, can someone help me? Thank you
also is working with just copy /paste the parts with no retargetting nothing

How do I find out the variable for the camera mode, 3rd or 1st Person? So I can hide only the head...
This seems cool and all, but when I try to create the IK Retargeter with your ALS rig, it just fails and says "couldn't create asset". :/
in ikr_als set the preview mesh to Anim_man
@XBcreations Not a super noob-friendly tutorial, then. All good I made my own IK rig from scratch. 👍
13.05 and its saddly not working
maybe drop updated video?
Does hiding (not removing) mesh have any impact on performance? Is it that hard to just replace it?
Take it out. See if it breaks. It likely will, as it is the parent of the Metahuman but it might be worth playing with. With the mesh not visible, there wouldn't be any graphic overhead anyway.

Does 5.1 have the hand placement problem? I used a similar solution in 5.0.3, the hand placement is not working correctly.
