Introduction to Maya - Rendering in Arnold
This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i

2 different joint types in an IK skeleton setup?
In an IK joint chain, there are 2 ‘joints’: the actual Joint (bone) and the IK FK Joint, one lying on top of the other.
But when i move the IK handle the 'other' joint doesn't follow. How do I solve this and what does it mean?
thanks

the FK IK joint (bone) display is just for reference. You can turn it off in prefs>kinematics if it bothers you
cheers

There are actually 3 joint chains:
- brown/maroon for IK
- dark blue for FK
- purple for the resulting blend of the IK and FK
Just to elaborate on this:
It's usefull when u want to overextend a joint what the IK handle won't allow (e.g. for an arm or leg).
You'd better use Animate>Ik/Fk Keys>Set Ik/FK key on the IK handle (never on the bones!!) to animate your blends and FK. Both Ik handle and the joints need to be keyframed or else freaky things start to happen with your IK solver.
Steps to blend from IK to FK:
1. Set IK/FK Key on the IK handle when Ik Blend in Channel box is still 1
2. move timeslider
3. set Ik Blend in Channel box to 0
4. Rotate joint
5. Set IK/FK Key on the IK handle
Do your FK animation using Set IK/FK Key on the IK handle
Steps to blend from FK to IK:
1. Set IK/FK Key on the IK handle when Ik Blend in Channel box is still 0
2. move timeslider
3. set Ik Blend in Channel box to 1
4. Rotate joint
5. Set IK/FK Key on the IK handle
Before and after your FK animation, you could just use regular Set Key to animate. Though this is when u will see a dark blue FK joint chain hanging from the top joint of your IK.
Attached is an illustration from the Maya manual.

for anyone else viewing this post, you can also turn off the display of the FK/IK bones (if it bothers you) in the preferences (Kinematics) section.
