Thanks! Very straight forward and flawless. I spent days trying to get this done on my own and ended up with a jumbled mess, a character that face plants when she lands, with arms that occasionally flip out and point backward, IK feet that do not work...the list continues. All the workaround I tried were mostly ineffective. After watching your tutorial, I only tried it once and bam! The end of frustration, frantic attempts to pull out my hair that were really shaved off and the relentless utterances of very colorful words. Thanks again. I have to say that this whole character re-targeting business in Unreal is rather convoluted and needlessly elaborate. In Unity it is simply “Make Humanoid, assign root...the end”. However, when things are finally working as they should, the gratification is a hell of a drug.

We could definitely use more mirror modifiers for managing bones. It's so awkward on some skeletons to get the right rotations to make the a-pose.

That was interesting. Thank you

Thanks for the Tutorial Matt. But do you think it is practical having 2 Mesh running on tick for game performance. and for a more practical scenario where we have to use BASE Class blueprint for multiple childs (as in multiple enemies, npcs) and call Mesh Component in Blueprints. Having TWO mesh will really mess up any other component, Spawn actors needed to attach on the mesh.

Nice thanks! Do you know if we can use animations from both skeleton? Ex. I want the animation created from Swat Skel to Aim, but I want the animation to run from Manny

Also click "Auto create retarget chains" UE5.4 knows what Mixamo skele looks like

Is this a good practice for packaged games? Seems like runtime retargeting is a resourced hog when I check unreal insights

@tehf00n 6 ай бұрын

Honestly when I use runtime retargetting with Metahumans I can package but when I run the packaged game it will crash randomly, rather quickly, due to an Async IK issue.

Please would it be possible for you to make a video that shows the exact opposite? I'm using GASP with Metahuman and an armor/weapons system, and the live retargeter is creating a problem. The gloves are slightly offset and so is the weapon at times. I'm sure it's the live retargeter that is the problem. Please

Thanks as always for the great tutorial! I have found auto-retargeting in 5.4.3 to be hit or miss. So, I'm still retargeting using the older method. I have a question: After retargeting all the anim assets from the source to the destination, I haven't been in the habit of manually assigning the exported anims to the actual skeleton of the destination character. Nevertheless, most of the time I get very good results. I always make IK Rigs. Is it redundant to assign the retargeted anim assets to the skeleton of the destination skeletal mesh? One more question, if you don't mind. I noticed that in your IK rig you didn't skip the twist bones in some of your chains. I've always skipped them. Is there an advantage to including them? The only thing I do differently is that I usually create a full-body solver, so I add end effectors on the hands and feet. I just bought a certain anim pack from the marketplace, and used the new workflow to a Metahuman (for a cinematic). They mostly work, but in some of the retargeted sequences, certain parts of her body visibly intersect. For example, if she's crossing her arms, or of maybe even both hands penetrate her torso. So I wonder if this is a result of not directly assigning these anims to the Metahuman skeleton. I assumed that that would happen automatically when using a correctly set-up retargeter and meticulous IK rigs for both the source and the destination. Can anyone who understands what I'm talking about set me straight? Thanks so much in advance!

You can sometimes get away with it if the skeletons are similar enough, however it’s always best practice to use the correct skeleton in case something goes wrong or a specific animation doesn’t work properly. The twist bones are used for more control over limb rotation, so I like to include them usually. However, I’m not the main animator on our team so there are definitely others who know more than me on that topic. But from my experience, I’ve had better results from including them as opposed to excluding them. Sometimes it’s trial and error to see what works best for your character, skeleton, and animations.

If you wanted to do this for multiple characters you would need to duplicate the 3rd person BP for each one to have them all in game at once?

is this tutorial for under ue5.4 versions? cause in ue5.4 there is a way more simpler way of doing this.

@MattAspland 6 ай бұрын

This was made in 5.3, that’s interesting though, I’ll have to take a look

@iateawaffle8184 6 ай бұрын

@@MattAsplandyea lmao in 5.4 if you open the retarget animations window and click on “export retarget assets” It will auto create the RTG assets with out you having to do it manually. (The only way that I know is to open the retarget window is to right click on any animation and click “retarget animations”)
