omg I spent all day trying to figure out the root bone scaling issue. Thank you for this!!
Thank you for this one, these issues are so common and can cause you many sleepless nights trying to figuring out yourself
06:10 root scale 100
06:40 unit scale 0.01 thank you!
Very useful video! Thank you very much, I spent several days looking for an answer on how to correctly export from Blender to Unreal Engine.
Bro. The root bone fix is a life saver. Thanks I was having problems retargeting the root everytime.
You just saved me hours upon hours of headaches looking for this fix. Granted, I don't doubt I'll run into more problems in the future due to being a novice at both Blender & UE5, but I was genuinely losing my mind w/ this issue. Thank you so much!
I spent 10 hours trying to get a simple chest to open up with an animation in unreal. This is the only video that gave beginning to end correct information. Thanks
10 hours? jesus
Thanks for the tutorial, you saved me a lot of time with the x100 scale issue, cannot thank you enough!
Thank you so much for this tutorial. The x100 scale problem was driving me crazy. Thank you!
Well made. 20 minutes and packed with information.
You have saved my life, thank you! Spent all day struggling with this and control rigs not working.
Hi!
I know this is an old video but i was looking all day to find away to figure this out!
Big thanks for this awsome video!
Thank you very much you are the only one who found the solution and shared it. The 100 scale was screwing up my control rig.
Cool! Thank you~ Finally, I understood what is LeafBone!
Seriously, thank you for the root bone scale fix!!!
Legend. Watching this a few hours ago would have saved me a big headache
I have been searching WHY my root bone added so much offset all the time. Thank you so much for this video 0.0
Super agradecido por tan buen tutorial!!!
Thank you. It's the best tutorial. Thank you.
Thanks a lot!I have been stuck with importing issues for a couple of hours.This clears up most of my confusion.
Great Job!
Much love. Thank you!
This is really helpful, thanks!
Thank you very much! It’s good to hear from you 😊
I was having issues with my control rig where on FK compilation the scale went all wack, ended up finding the scale issue by chance, which led me here, and this fixed it.
Life saver, thank you
Super helpful tutorial, thank you Daniel. Such annoying work arounds to get Blender rigging to work in standard game engines (Unreal/Unity).
Would be a dream if the Blender devs update the skeletal system some day to match industry standards. Or so your rig doesn't have to look like a crazy person made it with the leaf bones sticking out in every direction just to work when exported.
You gotta scour the internet just to piece together some common sense to get this basic stuff working. Every person has different settings and a different way that works for them. Its so ridiculous.
the bone system and units in blender + fbx format are to blame. its a nightmare
Would love to see some tutorials of you working with the models in unreal engine 5!
Thank you!! I've moved to Blender from Max and, although I like the interface, responsiveness and all, it does lack on some basic things like proper FBX handling.
Your video not only fixed the root x100 issue I was having, but it did it in the best way! Showing one issue at a time then how to fix each one. That's how we learn naturally, when we face the issues ourselves and I believe that's how I won't forget it so soon.
It also prepared me for the next time I start an Unreal scene in Blender. I'll know to set those units from the get go.
Again, thanks a lot!
Thank you!
Thank you so much man saved me
Thank you best video yet even though it’s long haha
Thank you!!!
OMG..Your are God!! Thank you for the tutorial it is much appreciated
great video
Thank you
Thanks for the tutorial! I have a question, I've tried retargeting my Blender character and the animation seems fine even though the orientation doesn't match the source mesh. Can you elaborate more about the problems that can be caused by the mismatch of orientation? Thanks!
It bet it was not easy to find this. Thank you very much. Like,Sub.
Hey great vids, im not 100% sure if this could work and dont have time atm to test myself.. but when it comes to the bone orientation (within belender) i wouldnt think you need to un-parent all the bones them manually rotate them to match orientations within unreal.. you can change the orientation of the bones within "edit mode" and clicking on "armature, bone roll, recalculate bone roll" to a certain axis without having to manually do it (i keep this added to my Q - quickfav menu).
maybe worth a try?
Great!
read every commend on commend section and multiply all thanks now you may understand all my respect toward you. Many Many THANKS. going to save as startup settings.
It took me an AI Google Assistant, to a Google search to RUclips on the internet browser, to RUclips on the internet browser in a new window to open in the app, to watch three ads, Just to watch this video 🎉🎉🎉🎉🎉🎉
comment for the algorithm. good vid
It blows my mind that this is the solution. It makes absolutely no sense to set the world scale to 0.01... I'm not angry at you at all. I'm angry at Blender... I have tried everything, and this seems like the only solution right now... Have you tried that Blender-To-Unreal-plugin?
Subscribed!
Do all of these problems also exist with Maya exporting to Unreal? I've only used Blender but I'm curious how other tools handle all these little annoying issues we keep running into.
5:08 But you did make that bone at 1:20 ??
14:30 what you mean by can't turn it? rotate it or roll it? in edit mode you can roll it with CTRL+R. While in pose mode just press R and the axis(X,Y,Z) you want it roll on two times. It will put rotation in local mode so you can roll the bone in place.
As I've seen bones work like that everywhere, parents affect child bones, I can't seem to get your point.
Just a heads up! having your bone orientations in Blender not aligned with that of Unreal won't become a problem when creating control/ik rigs, since you can set each ik controller's primary and secondary axis.
Tutorial of the Year 2023 ! Just one thing, when I rotate the bones and I came back to object mode, I rotate my mesh !
Hie, I'm not sure if it's covered here but I'm noticing that in my FBX animations that the thigh bones and calf bones are scaling and that cause like bobble movement on the foot in Unreal. Is this an export issue? Because I followed everything right with baked animations, no leaf bones and just deform bones.
my character still gets stretched and distorted for some reason when ever its from blender.. what else can i model with and export to ue5??
Calling the armature "Armature" is actually really important, otherwise you get an extra root bone level
Waju q buena escena
I can't understand how anyone could possibly consider this process acceptable. It's horrendous! There _must_ be a better way. There's no way in hell any modern game company goes through this nightmare of a process.
Not a single company uses blender . in fact no professional uses blender. Blender is not used at all in the industry. Even engineers of unreal engine uses 3ds max
@@adibrahman3321 That's simply not true. Blender is used all the time in the industry. Maya and Max are obviously much more common, but Blender is absolutely used.
@@clonkex Blender is used in the industry. But they have engineers to fix problems like this for them, in most cases. Or they know tricks a lot of times they have learned over the years that sometimes dont get shared outward
I’m having Some issues. First there are big spheres at the joints, about 100 times the size they should be. I also can’t use additive animations, I’ve done this before in other skeleton.
I’m using rigify quadruped and game rig tools core.
I know my comment is a little late, but what is the point of rotating the axis for each bone? Is it just for convenience sake when you go to animate later?
on the blender I have several objects put in a mesh, on unreal 4 everything is ok but when I send it on unreal 5 there is not a single mesh
I have a character where the eyes and hair mesh are child of the head bone, I tried importing it and the skeletal mesh looks weird, with the eyes missing and the hair with offset. However, the model looks fine in the animations!
but how to fix rotation, should be 0 0 0 but is 90,000000000000008 0,00000000000004 -0,00000000000004
Is there a way to fix the root bone scale WITHOUT breaking translations in animations?
I have a character that uses translation data in its animations, and applying the scale to the armature breaks those translations, and only rotation data is kept! I do not want to redo all my animations!
did you ever fixed this? im having same problem :/
Export/Import Failed , possible version issue?
how did you figure this out>?
X-axis: Forward
Y-axis: Right
Z-axis: Up
thats the right unreal settings. if you dont do that your orientation will be wrong. and do not maually scale you need to set up blender the correct way
谢谢，解决很多问题。请继续讲导出动画部分遇到的问题，这很重要_(:з」∠)_
you orientation z up x forward is 100% wrong in blender. do you accually know what oritation Unreal uses?
гуд
fooking microsoft xD
Thank u so much for the video, I struggled with the skeletal mesh for 2 days)
This did not work for me and broke my animations and character in engine
When i apply to scale to armature, the parented objects look like theyve been blown up. I am not clearing and reparenting as ive probably done it 5 times already trying to fix other problems. At this point im just going to ditch blender and use 3ds max.
Followed the same units/scale/export settings and Unreal is still making the root scale to 100. I've tried just about everyone's "solution" to the problem outside of buy the Better FBX plugin for Blender.
UPDATE! So my problems were that I had "Stretch to" constraints in my rig that were messing things up. For some reason applying the scale to the armature makes those constraints go haywire. To fix that, I disabled the constraint, added a new one and copied the exact settings and removed the previous bugged out constraint. Also, if you're using custom shapes for your control bones, be sure to scale those up too! If you don't then the bone controllers will become super tiny.
This is what I got after "Apply Scale": ruclips.net/video/SyxI6FeB-MU/видео.html
Well, I did everything and after all I realized something from this tutorial ruined my animation: and after few minutes and removing all my animation sets I found the issue: When I apply Scales on my Armature it does something weird with my animations, they all start to play like root bone is not on the middle of the character, his body now moves from center can can't move left
ight\up\down on animation it stays still on one point and just move bones like a doll, and also it even changed my animations FPS, it went to 30 instead of original 24....
So after all my inspects I tried to use "Ctrl+A->Scale To Deltas" instead of "Scale". And it works in the blender but after I import model to Unreal Engine it still has the x100 scale...
Any ideas how to fix scale and save animations?
Same problem here...
OK I fixed my problem. The problem here is when we "Apply Scale", everything get squashed except for the transforms in the keyframes of our animations. After I applied the same scale (x100) on the root bone's transforms of each keyframe as well (I used scripting), everything looks normal again.
Hello, can you help us with our project ? Like to have you with us with contract ?
Sounds very good and hopefully, but it doesn't work for my case, unfortunately. Struggling the exporting for three days already. Just a simple rig for IK control. All imported well, but when I try to connect effector control to Full Body IK node - mesh starts terrible wrapping. And the slightest movement of the effector leads to terrible, unpredictable movements of geometry.
The IK works correctly only when I keep the model very tiny (don't scale it by 100 skeleton and mesh). If I scale and then apply transforms - IK doesn't work, although the root bone scale is 1, in UE.
For some reason even doing the scaling trick still gives me a root scale of 1.75
Import Uniform Scale is an option and for some reason it was set to 1.75 as default.
check your email Daniel Kreuter pls
I have declined several times. Please stop sending me mails.
@@DanielKreuter so how can i contact you?
Just a heads up! having your bone orientations in Blender not aligned with that of Unreal won't become a problem when creating control/ik rigs, since you can set each ik controller's primary and secondary axis.
if bones in the chain have different primary/secondary axes tho its still a problem
