THIS TOOL IS AMAZING AND WORKS GREAT!!! just used it in maya 2019 with the LookRig characters! (only thing that you could maybe add is an attribute that transfers the Stretch values across between FK and IK in case the artist used limb Stretch. Other than that its an AMAZING tool !Thank you so much !

[@RedBull4Spirit]

Thank you for your Freedback Joe! I am happy the Tool helps you with your Animation. Feel free to rate the Tool on Highend3d, Gumroad or KZbin and share it with fellow animators. I note your request to add an attribute for Stretch value and add it to the next update if possible. Best wishes

Just bought this - its already saved my ass. Thanks for the great product.

[@RedBull4Spirit]

Thank you for the feedback. I am happy you find the tool helpful!

[@neohayabusa13]

I can't recommend this Enough! Get the Pro version, you will be glad you got it. Ps. I am very picky and if something sucks, I will right out say it, but this isn't the case. I bought the Pro version to help me Match from Ik to FK for my entire 500+ Frame animation. This tool saved me a huge headache on fixing spacing and momentum. My animation was complicated because I also even had translation enabled on my fk joints to cheat some stuff, and it still worked! Thank you very much to Monika for such an awesome Tool !

One issue I'm having is that the wrist control always moves to a different weird rotation whenever I switch from IK to FK

[@RedBull4Spirit]

You can use the Rotation offset attributes in the UI to fix this

[@matthewryfa]

For some reason, my Match IK >> FK works, but when I Match FK >> IK, it just reverts the FK arm back to its standard T-pose (neutral 0's on translations and rotations) and doesn't do anything to the IK control. It also creates a new "snapGrp," and I'm unsure what that is. The rig I'm using does have a Gimbal upper arm control (FK) in addition to the regular upper arm control (FK), so I'm wondering if that has something to do with it? But at the same time, it's the same setup for the legs, and the legs seem to work perfectly fine. The rig I'm using is the Rocket Girl Rig by vmcomix. Any suggestions?

[@tigrebttg]

I'm loving the plugin but can't get it to work with IK Wrist/Foot being anything else than the actual IK handle. Does the added Ik control shape thingy needs to be of a specific constraint/parent type? Thanks

[@theapexpredator157]

I'm actually trying to figure out how to Match the IK and FK of the default HumanIK Rig in Maya... Any help would be appreciated...

[@ahmetahmet4296]

Hi Monika. thank you for a perfect script. As a user of "Advanced Skeleton" rig system, I tried it. But I am getting error on hands. Arms fitting are ok But hands goes opposite rotation all the time. Advanced Sk. rig system as the same as you used in the video. Even the attributes etc.. But I am getting this unexpected result. What can be reason?

[@RedBull4Spirit]

Hello Ahmet, and thank you for your positve words. A arm rotation offset can be solved by adjusting the 'Rotation offset' attribute in the Setup section. I can say if there have been updates made on Advanced Skeleton that change the needed values for my script, but you can email me your Rig and I can test it for you. You write opposite rotation, so I would start with trying the values (180, 0, 0), or (0, 180, 0). Hope I can help

[@emirturkkal6833]

What rotation offset should I use to work (CGTarian’s) Ray rig's hands work properly?

[@zinne1978]

[@damocles5047]

Hello Monica Sensei. Can i ask you a question? Did you ever use animschool picker? there is this add command function in that small script, one simply can add mel or python events occured in the script editor. For example i set key on eyes default state then making the eyes blink and copying those both setattr lines. now i'm creating two buttons one default one blinked. so this is a great way to speed up the work but the problem is i just want to get the setattr lines occured in the script editor for fingers or other multiple controllers on a character. after posing fingers in different states like relax, fist, one finger pointed etc i just have to press enter for every finger controller one by one to get the setattr lines in the editor and paste them in the picker command button. so is there such script to select all finger controllers and get their values from chanel box? i just need rotate and translate but including other attributes would be great too.. The reason i'm asking this to you because i saw that your script's got this detect the matching switch attr function from channelbox.

[@Phen0o]

Amazing plugin, it helped me so much to save time in my workflow, instead of struggling. Thanks a lot Monika. I have a question still ^^ On the pro version, when you're baking from IK to FK, or the reverse, does it put keys on each frames of the controllers ? The free version works on Maya 2016, is the pro version work with Maya 2016 to ? Thanks for your answer ;)

[@RedBull4Spirit]

Thank you for your comment and using the IkFkSwitch. For you question, the pro version 'bake range' bakes the ik/fk controller on every frame. And yes, the pro works for 2016 too. Enjoy the tool and hit me up if you have further questions.

[@Phen0o]

@@RedBull4Spirit Thanks for your answer

[@tonyisonfire]

is that working for rigs with more than 4 limbs? like spiders or dragons ( with wings ) for the baking option I'd add the "freeze viewport" option in the UI

[@RedBull4Spirit]

Thank you for your comment. The tool is only set up to work with 4 limbs. I am going to add the freeze viewport for the next iteration.

when i do the 'Match FK >> IK' I sometimes keep getting this error --> mog_ikFkSwitch.py line 488: invalid literal for int() with base 10: 'q'.. Most of the other times the location of the joints matches perfectly but the pole vector doesn't and this causes the leg or the arm to twist in a ridiculous angle. Thus, the pole vector is my only issue. Please could you help me out with this?

There have been several updates to the script. The error should be resolved. you can download the latest version of the script.

Monika, can you discuss if this script of yours works with Human IK in Maya and whether it provides any advantages in that environment? I'm still in pre-production so I'm trying to figure out which 'rig' to use. And I have the HIK stuff working but am thinking about Advanced Skeleton. Your tool appears to be very handy though for the animation workflows I am considering. LMK. Thanks.

I've tried this on two rigs including Beefy (www.highend3d.com/maya/downloads/character-rigs/c/ultimate-beefy-for-maya) and I can't get it to work properly. Upon trying to match my FK arms to my IK arm pose, the arm is rotated to a completely different position. And when matching IK to FK, the pole vector and elbow ends up in the wrong place. Could you please try it with this rig and let me know if you have this issue too?

Hello Big-Art Kolins. I am happy to help you solve your problem. Please send me an e-mail with screenshots of your UI Setup settings as well as information on the character you are using. Each rig is different and the script has ways to adjust for things via the rotation offset values in the Setup section. You can find my e-mail in the scripts source code or description file. Best, Monika

[@team-chonk6542]

Does not work in maya 2018 using the ultimate bony rig, the pole vector/elbow control flies off a mile away once converting FK to IK... and matching IK to FK sends the controls all over the place, i followed your steps exactly, i double checked, I also tested on another rig (Ray) and it works fine, why doesnt it work on the Bony rig?

[@RedBull4Spirit]

Hello. The Script depends on the controls pivot and transformation data set up by the Rigger. Zero FK controls should put the character in t-position I can calculate the angle from an rebuild the in/fk relationship. I can't tell why 'bony' rig in particular is not working. Is there anything locked or scaled on the controls? What does zeroing out the controls do? There are exceptions and different built rigs that won't work but I try to test as many Riggs as possible and update the script if I find a solution or workaround. Is this 'bony' rigg open source? Can you send me a link where I download it? I can do some testing and let you know why it won't work.

[@team-chonk6542]

@@RedBull4Spirit Yeah ultimate bony rig is free and common, here www.highend3d.com/maya/downloads/character-rigs/c/ultimate-bony-for-maya Zeroing out does put it back in t pose yes, I notice some rotations are in reverse to the opposite side (one rotates in positive and one in negative) As for the other questions im really not sure, little too advanced for me sorry lol

[@patrickhamu8146]

Thank you very much for this script. It worked perfectly for the arms but the legs it seems like there is a rotation problem from the knees. How can I fix?

[@RedBull4Spirit]

Hello Patrick. I am glad the script is useful for you. If there is a rotation offset, you need to put in a value to the Rotation Offset field in the Setup, then Update/Save before klicking the Match again. Ther value you need to put in is the inverse of the offset you get. So if you have i flip in X, the X Offset would be 180. I hope this makes sense and helps

[@cloudshifter]

What if the rig has 4 hands for example? I want to have 2 left hands and 2 right hands being able to switch fk / ik and vice versa. Is there a feature for this? If you don't have the pro mode do you have to set it up every time you open Maya?

[@RedBull4Spirit]

You can set up store nodes for all 4 hands and it will recognize based on selection on what Arm to switch. The setup is saved in the scene, also in the Free version, you just can't export it to other scenes with the Free. I recommend you test your multiple arm setup with the free version before purchasing

[@cloudshifter]

@@RedBull4Spirit I have one more question. For some reason when I press, match Fk to Ik and vice versa it does the opposite, it connects Ik to Fk (and vice versa as well) is it perhaps a error when choosing what the 0 value is (fk or Ik on the model)? Cause I think I did got the 0 value on the switch control correct. Also, out of the blue randomly when it worked just fine it told me via script editor that it can't translate the command into Maya binary or something. If that last one doesn't make sense I will inform you again if I get that message and write it down.
