On latest RRM3 (though it's been a problem in previous versions) create any new rig (let's just use the Biped template). No need to customize anything. Generate the rig. Now the global control (with RRM3 branding on it) cannot normally be changed or customized in the UI, it throws a warning "cannot swap Main_Ctrl shape". But let's say you decide to help it along by unlocking some of the shapes on the control and changing it 😇 For repro purposes, unlock and delete the RRM3 text. Now try and regenerate the rig, making sure Keep Current Control Shapes is ticked. It will hang on Loading Control Shapes Data step with the traceback: Loading control shapes # Traceback (most recent call last): # File "C:\ProgramData/Autodesk/ApplicationPlugins\rrm3\Contents\scripts\gui\main_tabs_generate_rig.py", line 619, in <lambda> # self.rebuild_rig_button.clicked.connect(lambda *args: self.rebuild_rig_checks()) # File "C:\ProgramData/Autodesk/ApplicationPlugins\rrm3\Contents\scripts\gui\main_tabs_generate_rig.py", line 770, in rebuild_rig_checks # rebuild_rig.rebuild_rig(rig_top_node, joint_rot_override, preserve_skinning, reuse_ctrl_shapes, # File "C:\ProgramData/Autodesk/ApplicationPlugins\rrm3\Contents\scripts\control_rig\rig_post_build\rebuild_rig.py", line 238, in rebuild_rig # read_ctrl_curve_data(rig_top_node, ctrl_curve_shape_data_file_name) # File "C:\ProgramData/Autodesk/ApplicationPlugins\rrm3\Contents\scripts\control_rig\rig_post_build\rebuild_rig.py", line 615, in read_ctrl_curve_data # convert_curve_to_code.load_ctrl_data_from_file(rig_name, ctrl_curve_shape_data_file_name) # File "C:\ProgramData/Autodesk/ApplicationPlugins\rrm3\Contents\scripts\control_rig\convert_curve_to_code.py", line 273, in load_ctrl_data_from_file # cmds.delete(original_shapes) # RuntimeError: # Cannot delete locked node 'Main_Ctrl_R1_OuterCurveShape'. # Cannot delete locked node 'Main_Ctrl_R1_InnerCurveShape'. # Cannot delete locked node 'Main_Ctrl_R2_OuterCurveShape'. # Cannot delete locked node 'Main_Ctrl_R2_InnerCurveShape'. # Cannot delete locked node 'Main_Ctrl_M_CurveShape'. Cannot delete locked node 'Main_Ctrl_3Shape'. I guess it's up to you whether this gets fixed because I wasn't "supposed" to mess around with this control. But it seems weird that this is the one control you cannot customize because in my pipeline, this is one of the few controls that I DO customize. On my end I've just been careful to save this step for last, knowing that it will disable my ability to easily regenerate the rig once I do.

Create a rig using the biped proxy template. Go into one of the elbow controls and mess with the Angle Offset. Attempt to mirror the controls to the other arm. Notice that the Angle Offset does not get mirrored. It will get mirrored on the Legs, just not the Arms.

On latest RRM3 (I think, the version number hasn't changed the last several times) create a new rig with the biped template. Don't change anything, it's not necessary. Generate the rig. Select an arm and switch to IK mode. Change the IK control to follow Spline Top. Try and move Spline Top. The arm IK doesn't follow. Does not seem to be an issue with any of the other follow spaces or with the legs follow spaces, just the arms with Spline IK Top.

Hi all, just trying to get RRM3 up and running in my preferred Maya Version, 2022.4. I installed to the default location. The plugin doesn't show up in Plugin Manager, so I go to Browse ---> C:\ProgramData\Autodesk\ApplicationPlugins\rrm3\Contents\plug-ins\2022\rapidrig_modular_v3.py When I load this, what appears in the Plugin Manager instead is __init__.py, and trying to load that generates the following error: // Error: file: C:/Program Files/Autodesk/Maya2022/scripts/others/pluginWin.mel line 316: (__init__) // I can get the plugin to load normally following these same steps in Maya 2023. Any help is appreciated.
