I can confirm the bug. Looking if @Joshua Leung (aligorith) 's fix is breaking something else.

Not sure it's a complete solution tough.
Then if hand_fk is not visible the problem remains. I guess exposing a separate bone at the limb's first bone to handle all the properties is a better idea. This bone can be on both FK and IK rig-layer meaning it's always visibile if at least one of them is.
Will look further into that.

This is fixed in 2.79. Now the property is moved to a visible bone laying at the base of the limb.

• New rigs created starting from 2.79 code will work automatically.
• Old rigs should be upgraded re-assigning the rigify-types property in pose mode.

Sorry for asking here, why does blender documentation talk about v 0.5 while blender comes with v0.4?

@Rombout Versluijs (rombout)
Rigify 0.5 is bundled with blender 2.79. The documentation is referred to the upcoming 2.79 release. Since 0.5 is a major change and the old rigify was never documented and its code is going to be deprecated anyway, we decided to refer the documentation explicitly to Rigify 0.5.
If you want to test it grab your test build here: Blender 2.79 RC1

btw this wasn't the right place to ask.

cheers,

Thanks! Sorry about the fuzz. But a little text there cant do harm. Know i went searching and searching, when i could have a little piece of text saying "this documentation is for the upcoming 2.79".

@Rombout Versluijs (rombout), maybe you missed the first lines of the page. There's a header that states the version of the add-on and the blender release.

Sorry but what page are you talking about? I think your talking about inside pages. Go check the link in the addon in lbender and see what info is there

@Rombout Versluijs (rombout) is the official rigify wiki page and, as i wrote previously, there's no other one since it documented for the first time in 0.5. Please look further before posting next time. And stop posting here if your question is not relevant to the topic and you already had support.

i'll post again the useful information you already had in the previous post in case you missed it:

that page is irrelevant to the the current version, acknowledge it, just saying. I took me quite some time to fin dout out this is coming for 2.79. How hard is to put 1 line on that page. Perhaps it was changed in recent days. But it was not saying blender 2.79 2 days ago. I now see blender 2.79

@Rombout Versluijs (rombout), the header was done before the documentation, so the only chance is you missed it.
I think there are only two different scenarios here:

1. the user has blender2.78 or previous. In this case he can easily see the bundled version is 0.4 and mismatches the documentation header. The documentation and release changelog state also with extreme clarity what's changed in 0.5 (Please Read: What's new in Rigify 0.5) so if the feature you are looking for is in 0.5 updates list he just grab the 2.79 and goes. As long as he can read english i can't see a real problem.
2. the user has blender2.79 or newer. The problem doesn't exist at all.

I am spending time on this, hoping to leave a trace for other user may have missed that lines too giving them useful information on how to approach to versioning and documentation by themselves, but is my last post on this OFF-TOPIC thread. I am asking you again to please stop posting here if your question is not relevant to the topic and you already had support.
If you do, you know why you will get no other answers from me.

Cheers,

okay i understand. But i think there other uesres out here with the same "problem".

This line perhaps needs to be a bit more clear;
"WARNING!
RIGIFY 0.5 DOCUMENTATION PROCESS IS STILL ONGOING! WILL HOPEFULLY BE FULLY ONLINE BEFORE 2.79 FINAL RELEASE DATE.
