Thanks. Finally my coed worked !

[@daweiwang-tx6bq]

thanks a lot

[@marekbarski3708]

thanks! work fine

[@fade7955]

i really appreciate the tutorial. I was looking for a way to give get an idle animation. as far as I can tell, this example uses the "woman_idle_testJaw_2" animation sequence. Is there a way for me to get that animation somewhere?

[@metahumansdk]

Hi! You can find any idle animation in the public domain. For this case, the animation was created by our animator.

[@DaBarkle]

Hey mate, have looked everywhere on the internet for a fix, my issue is that occasionally the metahuman face animation repeats. Not sure if this is a bug. I have implemented it exactly as you have done. Restarting unreal engine seems to make the bug go away, but then it comes back. Running unreal 5.2. Wondering if you have encountered a similar issue. Example is it will play the face animation in sync with the sound, but then the face animation continues to repeat the same a few times over.

[@metahumansdk]

Hi! It looks like the state machine logic need some corrections. Perhaps avatar's face animation blueprint can't switch correctly between idle and generated animation. Try to add some merkers of the animation lenght like in this video at 3:50 More details about state machines you can find in the Unreal documentation docs.unrealengine.com/5.2/en-US/state-machines-in-unreal-engine/

[@enzorobillard8822]

Thank you for your help, your video is very useful!! Would it be possible to have the "WomanIdle_test_jaw" file? On what software was this FBX file made? Thanks in advance ! 😁

[@metahumansdk]

Hi! For this case, the animation was created by our animator. You can find any idle animation in the public domain and use it with our plugin with your character.

[@sinaflair]

the level being used here doesn't seem to exist anymore, there is a level called sound2talk but when clicking on level blueprint it looks different.

[@metahumansdk]

Hi! This is true but we prepared demo project for 5.2 with ChatGPT and shared it in our discord server. This project include MetahumanSDK and OpenAI plugins so you need to disable same plugins from marketplace to run project correctly. Also it will ask you to rebuild the plugins. To rebuild them you need to install VS 2019 with required parameters from Unreal Engine documentation docs.unrealengine.com/5.2/en-US/setting-up-visual-studio-development-environment-for-cplusplus-projects-in-unreal-engine/ Link to the discord message discord.com/channels/1010548957258186792/1068067265506967553/1143934803197034637

Thank you this was incredibly useful!

[@mumuhmuhaemin997]

Hi, very interesting. My work got stuck at 2:55 seconds when I had to enter womanIdle_testJaw_2 (Animation Sequence). What are the steps to making it? I've tried several idle animation in public domains, but with no luck. I really hope you can help by showing us how or by telling us which domains we can use. That way, we can complete this project perfectly. Thanks. I'm waiting for your reply

[@metahumansdk]

Hi! If you want to make fast idle animation you can use wave file without any sound and just create lipsync then play it forward and backward to cycling 😉

[@alexdjulin]

Exactly what I was looking for, thank you so much!

[@san-qn7ci]

Sir, I think this is not a tutorial about detachment issue from the body and head. It looks like just voice method that you guys working on it... Can you provide us ideal solution of detachment problem? face Animation and Body animation plays differently it selfs, not connected. face floating around all the time at sequence.

[@metahumansdk]

Hi! Main point of the video is Layered Blend Per Bone node in the Face AnimBP that you use on the head to play animations. If you trying to send animations to the head mesh directly like asset head will separate from the body and will play animation as independed mesh. If you need details about this guide please send your Face AnimBP to our discord or [e-mail]

[@vaibhavdevadiga9807]

For the chat bot integration, will this head detachment fix work? If so what are the changes that we need to make here.

[@metahumansdk]

Hi! The main point is conect your animation node to the Cached Body Pose node and connect Cached Body Pose to the Layered Blend Per Bone node. This tutorial shows much more details about work with animations but the main point is use Body Pose and Layered Blend Per Bone.

[@justinjin5675]

​@@metahumansdk Same question, still kind of new to UE, can you give a little bit more specific instructions about the part you mentioned above? Thank you.

[@metahumansdk]

@justinjin5675, we shared answer with screenshots in our discord discord.com/channels/1010548957258186792/1201940084279222332/1202751820187836446 You need to modify your facial animation blueprint to glue avatar's head to the body.

[@alejandroescudero565]

Hello, excellent tutorial! I have a problem; my idle animation doesn't blink. Is there any way to solve this? (I've checked the blink option during the animation creation process). thnks 4 all

[@metahumansdk]

Hi! If you create an idle from our plugin you need to enable Generate Eye Movement.

[@alejandroescudero565]

@@metahumansdk I found the problem, I had to have the "EPose" option enabled, since then it's blinking. Another question, do you know of any tutorial for doing "look at camera"? thnks you so much

Why doesn't the voice and the mouth shape match after each play, and the mouth shape ends first? Preparing Animation Sequences are displayed in the upper left corner.

[@metahumansdk]

Hi! This video filmed as screencast from the editor. Usually it goes fine on the rendered videos from the sequencer and in the packaged projects.

[@mustafayenerkol9958]

Hi, I am using unreal engin 5.3.2. There are 2 projects. I download the same metahuman from quixel and apply the same animation. In one project the head separates, in the other project it does not. I don't know what the difference is. Do you have any possible ideas?

[@metahumansdk]

Hi! Metahuman have different skeletons for the body and the face. If you send the animation to the head skeleton directly, the head will take the default position for its coordinate system. Therefore, it is necessary to use the animation Blueprint for the face and use the Blend Per Bone node to specify the root bones to map the head position to the body position.

[@xXArtCharXx]

This works, except my Face Blueprint is playing on start and playing after every question my chat bot asks. What setting am I missing?

[@metahumansdk]

Hi! There is too many ways where it can be broken. Can you share more details in our discord server? discord.gg/MJmAaqtdN8

[@inteligenciamilgrau]

2:12 For me, just don't have "Blend Pose 1", only 0 and the other! What I'm need to do? Thankxxxxx

[@metahumansdk]

You can manually add it in the Layered Blend Per Bone node

[@user-nn7mg3bp4u]

has to be an easier way!

[@themistermillson]

Hi, I can't get the body animation to work at 6.17. The anim file is fine but does not work when I play.

[@inteligenciamilgrau]

4:42 I didn't find this Event AnimNotify _EnterFaceAnim! What I missed?

[@metahumansdk]

Hi! At the 3:27 you can find short moment where we named Custom Blueprint Event as FaceAnim. It should fix your project.

[@xinzhangxin477]

Why is there only one action asset without Anim in the animation pose that appeared at 1:02?

[@metahumansdk]

Hi! In this video we will use animation later. At the 1:02 in the Mappings mode we set mapping for MetaHuman to make it work with MetaHumans.
