IK/FK Snap addon for Blender

[@GregoryBrownAnimation]

Just added it to my project. It works great! Thanks for the amazing work. This is going to save so much time for my animations. P.S. For those who are getting errors when trying to snap! (I'm not sure if this was addressed in the video or not. If so my apologies) Make sure the name of your Armature in the object properties tab (The orange box) and the Armature Object DATA properties tab (The green Armature figure) are the same otherwise the script can't find the armature you're trying to use.

[@AnimatorBlender]

Have you tried using it for the legs (it works perfectly on the arms)

[@halilkunge9295]

Snapping from FK to IK works fine but from Ik to fk doesn't work. I'm running blender 3.2. Could that be the problem?

[@Callvix]

Thank you!!!!!!!!!!

[@GANONdork123]

This addon looks fantastic! It's kind of baffling that Blender doesn't have a feature built in to handle IK-FK snapping automatically, as it seems like such an obvious thing to include.

[@excessoats]

What incredible timing to drop this 🥲

[@Nyubug]

Why can't there be something similar to the "Auto IK" toggle button that allows you to simply toggle the IK or FK seamlessly?

[@CosmicCupidForges]

I have the 4.2 addon that's branched from your code, and I gotta say thank you so much for letting me skip integrating python code into my project!

Great Job！It's really useful，Thank you!

[@teneesh3376]

I wonder how well this for more non traditional human characters or non human characters. Like ones with 3 elbows, or the fk is bendy bones

[@MondyTS]

Can't wait to try it out!

[@alan112223]

Thanks man, this is very helpful

[@soirema]

This is amazing, thank you so much!

[@pistoleiropapaco5178]

Amazing, thank you so much!

[@georgegibson707]

Thanks for this, can you or anyone suggest a tutorial or info on how to convert a standard FK metarig to add IK control, compatible with this add on ?

[@Thunder_Owl]

Thank you for work and sharing !

[@CrackedCreativity]

Hey! im having some issues setting it up with a mixamo addon rig. I cant seem to find the IK bones in the bone list(Its not there) if anyone can help it would be highly appreciated thanks

[@EstherSuus]

Hi there, thank you very much for the video and the addon. I do have a chalenge with the addon and that is that I have 4 bones in a leg instead of 3. Can you tell me how i could use/ change the addon for a situation like that?

[@qasai3840]

Hey could you help me out. Im trying to apply your script to my rig but its giving me an error everytime I try to snap the fk/iks. KeyError: 'bpy_prop_collection[key]: key "Armature (pmc-4.qc_skeleton)" not found' Armature (pmc-4.qc_skeleton) being my armature name. Any idea how I could fix this?

[@Sandyy_sandy]

rename the Armature the same as the object name

[@AnimatorBlender]

LOVELY!!!!😉😊

[@shivangipriya4153]

Any picker for IU bone picker ?? add on ?? I could not find only with auto rig I need to for meta Rig

[@Kayosupergamer]

I using this addon so much and its really helpful, but I have one tip and feedback, in armature filed where you input your armature and after the all config to switch , you need to create a preset to change between arm fk-ik left and right side, and the same thing to legs, so you will have 4 preset, but, I note that the preset is saved in the blender preferences, so when I open other project with other character and other armature the same preset is there, and I think this is a problem, because if I change the preset and return to my first project, will be change too I think, so how save the preset only in the one project ??? have any idea?? or it will be implement some solution in the future?

[@Mystfit]

Thanks for the feedback, I'll see if I can make an option to save addon presets relative to a project file.

[@soirema]

I see that you have been doing p2design tutorial :D

[@isaacfields7923]

Whenever I attempt to use the snap it gives me a key error: bpy_prop_collection[key]: key "(character name) Robot Rig" not found. I could use some help. Edit: I fixed it. The error was because my rig and armature's name within the container were not identical. It works now. P.S. if and when you make an updated version, may I suggest you add functionality to snap additional bones such as foot roll bones. Because as is if the ik foot is foot rolled and you snap IK to FK you have to manually reset the foot roll. Preferably the IK to FK snap could be set up to reset any amount of additional bones as my rigs usually have two foot roll controllers. One to tilt the foot side-to-side, roll forward and back, and rotate in and out on the heel and a second bone to move and pivot the foot by the tip of the toes. As is it isn't the end of the world. It would just be nice.

[@jonevarty2205]

Thank you so much. Was running into this same issue.

[@stephanenicault4939]

Thank you very much.

[@OfficialAEPBR]

Does this work with rigs with just one arm setup and not 2 where one is fk and one is ik?

[@alimoworld8295]

Thanks a lot, I have a question. in leg we have 4 fk bone , how we can setup that? (feet + toe)

[@Mystfit]

At the moment the addon only works with two-bone chains. I'd like to add support in the future to have an arbitrary number of IK/FK bones in a chain plus the end control

[@AnimatorBlender]

what about for the legs?

[@AnimatorBlender]

i can't find an extra slot to accomodate all4 leg bones

[@AnimatorBlender]

is there a way to add a slot?

[@Mystfit]

Unfortunately not easily at this stage, the script at the moment is limited to two-bone IK chains. How many bones in your leg do you have? I'll investigate if it is possible to use an array of bones instead.

[@AnimatorBlender]

@@Mystfit my leg has four bones

[@apraxas]

@@Mystfit Hello Hello! Any update in this regard? I was checking and Rigify's code seems to handle snap functions for longer chains well, so the code maybe could be referenced?

[@edisoncastaneda3327]

OK now question. Will it work if there is a multiple rig on the scene or it's just good for 1 character per scene?

[@Mystfit]

Each preset you save should have the armature saved as well. This does mean you can use this with multiple characters but the presets list may get a bit full. I'd like to add per-armature preset filtering at some stage.

[@danielaguila4085]

save my life!!! thanks

[@TinNguyen-wx4fq]

Good job

[@ninhthinh4028]

I can snap FK-IK but IK-FK doesn't work

[@ninhthinh4028]

I figured it out, if you want IK snap to FK you have to put Up-Arm FK and IK in the same place
