Hello !
Just a little issue on mGear, not important but if you have a guide in your scene and you’re skinning a geo while the Guide Explorer is shown, maya flickers with the message “// No referenced groups found to refresh.”
So it’s impossible skin a mesh while the Guide Explorer is open.
Repro steps :
- Create a control_01 guide, and check “joint” in the settings
- Build
- Create a cube
- Skin the joint to the cube
- Go to Shifter Guide Manager > Guide Explorer and keep the window shown.
- Go to ngSkinTools and click on “Paint” to start painting.
Now ngSkintools glitches with mgear window and all maya since you jump back to the tab “Components” of the guide manager or you disable paint mode in ngskintools.
The issue come from the way the Guide Explorer is displaying widgets :
