My god, this is the fourth tutorial I've watched and your solution finally worked for me! Thank you!

[@makeyourgame2210]

OMG Dude thanks you this is the best tutorial ive ever seen about IK!

[@crisppxls]

Fantastic tutorial. Managed to get my 4 legged character working with this setup, appreciate the help

[@muller_digital]

Nice work! Glad it helped!

[@procrastinator24]

Great Video, Thank you so much! One thing I was wondering is why you did not expose the rotation of the goals and threw the rotation directly in there, but other than that everything was perfectly understandable :) thanks again!

[@YEAHSURETHINGMAN]

The timing of this tutorial couldn't have been any better! I followed your last tutorial (which was amazing btw) and yes, this is exactly what I wanted to implement next, but most IK tutorials I have seen only use ue5 manny - THANK YOU :)

[@muller_digital]

Supper happy you like it! 😎

[@olliverkatana4168]

Very cool and clear tutorial. Thank's.

[@letsplayprojektorix545]

I had the problem that the character started to fidget at a certain distance when you moved away from him. If anyone has this problem, it occurs when the next LOD level becomes active. The solution for me was to increase the "min Lod Model" in the character from 0 to 4. And the problem was solved.

thanks bro i was wondering on doing this in my game

[@rezaj.mousavi7310]

Thank you for your training, only which numbers can be changed if the amount of stairs is higher? Thank you for your attention.

[@lasciviousembrace]

Could someone please tell me how to also do this with the whole body? I followed the same steps after doing the feet, but when I align the body to the floor too, the feet move all over the place.

[@SergeyBel]

I dont know what I am doing wrong but the foot does not move lower or higher nor the root nor the pelvis/hips

[@Gravigenesis]

Я использовал вместо break vector 3f просто break vector,у меня нет такой функции и не сгибаются колени

[@paleobiome]

great tutorial, but it took me 3 days to find out how to re use the ik rig to a secondary character, the problem was that in AnimBP - EventGraph you used casting and it meant i could only be used for that single character, i'm looking to alternatives for casting now

[@lianna5483]

Hello there, thanks for the video. :) I can't find Atan2 in my blueprint functions. According to unreal 5.3 documentation, it is in Kismet Math library but I cannot manage how to activate this in blueprint. Could you help me with that please ?

[@FPChris]

Great tutorial.

[@tshanks3741]

Thank you!

[@crs11becausecrs10wastaken]

Pelvis issues, it won't offset to the lower foot and causes over exertion. :( To fix this, (an over simplification) I did a branch to compare if the left or right foot was lower than the other. If so, then offset the pelvis position by -2.

[@DJDeity17]

Its crazy how complicated it can be to just keep your characters feet on the GROUND!!

[@muller_digital]

Right!

[@jimmyjones3200]

Hey, Sorry i have another question and this one, i cant quite figure out. When on a slope. My characters legs don't move up/down enough to counter the slopes angle. Anyone know how i can edit this? Thanks

[@jamaalsineke2405]

Lekker Bru!Shot for the tut

[@allalongthewatchtwer]

could you replicate this with a horse model? the pack I took it from says that it's rigged for the ik

[@ABentPaperclip]

curious why you are using IKRig for this when most of the newer examples seem to be using control rig? for example- the third person mannequin uses a control rig for this- is there a benefit to using one over the other?

[@muller_digital]

I find this solution a bit simpler, both work. Sometimes control rigs can be buggy with certain characters. A good control rig is definitely better in the long run id say

[@FPChris]

At the end 22:45 ish when he is walking on flat ground it looks "off" to me. Can you disable it when Z is 0 so that the original walk anim isn't effected?

[@al-tayf]

Hey bro , Im finding something to fix the hands going inside the objects while ongoing animation. Is there any fix?, Im newbie and i dont know alot about ue5.. It will be so grateful for me if you show your kindness, Hoping for your response, Thanks.

[@jimmyjones3200]

Hello, for some reason after adding the goals. When I go to move them around to test, even the slightest of movement make my characters whole body freak out. Can anyone offer any help?

[@jimmyjones3200]

anyone else comes across the issue. Click full body IK. Then in the inspector tab, change mass multiplier to 1 instead 0.1. The problem was due to my character being imported in a different size to regular mannakins.

[@trueforgefathervulkanhesta4045]

-I don't get why my IK rig in animgraph does not change when i pick IK rig.- Okay figured. This method worked on imported monster.

[@Ababa3256]

How did you solve it?

[@trueforgefathervulkanhesta4045]

@@Ababa3256 There was something wrong picked in animgraph if i remember right.

[@YEAHSURETHINGMAN]

Haha I tried using mixamo to upload the steam boat willie character from sketchfab but it was all messed up, just curious where you got that model? :) Thanks

[@muller_digital]

I got it from sketchfab aswell. I just imported into blender and removed the tail, then exported it from blender again. That export settings from my previous video ussally always work. And the tail is put back afterwards with cloth simulation. Its for an upcoming video im working on😎😎

hit game idea micro mini multiverse cells a game about creating cells that produce micro mini multiverses

[@TheNutsNetwork]

Any chance this would work on a 4 legged skeletal mesh? :)

[@muller_digital]

Im sure it would! I would add 2 sockets instead of one for the reference to root. And then just repeat the process for front legs and the back legs. So code will be a bit longer. But if you got a good grasp on whats going on you should be able to figure it out! Let me know how it goes and maybe I can help you along the way

[@TheNutsNetwork]

Thanks for the quick response! I will try this :) @@muller_digital
