Manipulator not working

Milio · 6 August 2026 14:14

Hi! I have been trying to find a solution but couldn’t find anything.

I updated to the latest version 20206.07.30 and the manipulator does nothing.

The UI pops up, but clicking anywhere makes it disappear.

Am I missing anything?

Cheers.

Hi @Milio

I have tested on my side, but not sure what went wrong, so I need a bit more details from you

What feature were you expecting when entering the manipulator mode?

By “UI”, I assume you meant the manipulator UI, but I cannot make it disappear by clicking anywhere in the viewport. If it was manipualtor UI disappearing, the UI that has Shape | Limit | Scale | Pose | Play tabs on the top-left corner, that would mean the solver or marker node was not selected. If so, can you tell what was selected instead?

Milio · 7 August 2026 07:33

Exactly, the UI appears, but trying to click on anything makes the UI disappear.

Milio · 7 August 2026 07:34

I expected, like the previous version, to be able to change rigid bodies, limits etc.

Thanks for the screen recording!

Looks like there are some monitor DPI issue. When you move your mouse cursor over any button, can you see any button become a little bit brighter?

Please try Ctrl + = and Ctrl + -, that should scale up/down manipulator UI, see if that helps.

Also, from Windows Settings, can you tell me your monitor display resolution and scale?

Milio · 7 August 2026 08:26

Making UI bigger is not fixing it. Nothing happens when going over the icons.
,

Not sure why the scale is greyed out, but it is a 4k monitor, not scaled, 100%

Maya is 125%

Milio · 7 August 2026 08:33

Managed to get the scale to 100%. Same problem. 8-(

Milio · 7 August 2026 08:39

theres a bunch of versions here, i’ll clean those up and reinstall again. Cheers

davidlatwe · 7 August 2026 08:45

Thanks @Milio

Did the manipulator from Ragdoll 2026.02.13 works for you? What was the last working verison on you side?

Milio · 7 August 2026 08:52

Cleaned up all versions, re-installed, same issue.
The previous version was RagdollCore-2026.03.10 and the manipulator did work fine.
I started using it again recently and updated to the latest yesterday.

Hi @Milio

Here is a Python script that we need you to run in Maya.

ragdoll_support_probe.py (10.8 KB)

It will print out details like monitor dimensions into your Maya ScriptEditor and hope you can share with us. No sensitive info will be exposed, safe to paste here.

Steps to run:

Launch Maya, load Ragdoll scene
Activate manipulator
Open Maya ScriptEditor, drag-drop the script into a Python tab
Execute
Move your mouse cursor into viewport, click on a manipulator button
Done, copy the script output

Hi @Milio

Looks like there was no mouse click after script execution? Or you did, which might be another problem that is unrelated to DPI scaling.

I have updated the test script, please download it here.

ragdoll_support_probe_v2.py (16.6 KB)

Steps to run:

Launch Maya, load Ragdoll scene
Activate manipulator
Open Maya ScriptEditor, drag-drop the script into a Python tab
Execute
Make 3 mouse clicks (as the instruction you will see in ScriptEditor):
- Click - Ragdoll manipulator UI button
- Click - Empty area of the Maya 3D viewport
- Click - Maya UI, shelf or top mean bar
Done, copy the script output

[step 2/3] CLICK once on an EMPTY area of the 3D viewport.

[step 3/3] CLICK once on a shelf button or a menu. This LAST click ends the test and prints the final report.

Those are the test results; sorry, I was a bit busy this week. Cheers.

davidlatwe · 12 August 2026 08:32

Thanks @Milio !

This really helps, we have confrimed the problem. It was becaue you were using DirectX as Maya viewport rendering engine.

Can you try OpenGL for now, to see if this problem goes away?

Once confirmed, we will make a fix release for this soon!

Milio · 12 August 2026 09:01

Yep, it is due to the DX setting. We are forced to use it by the client, though. 8-(

marcus · 12 August 2026 09:07

This is the usual reason anyone uses DirectX. Thanks for reporting this @Milio, we’ll patch this up and make a new release before the week is over.

davidlatwe · 12 August 2026 14:21

Hey @Milio

New release is up, please have a try. Thanks!

Milio · 19 August 2026 06:33

I can happily confirm that installing the latest version fixed the issue!

Thanks a lot!!
