Why this is happening to my proxies?

Thank You in advance.

The scene was in centimeters. When i import obj-s, this happends also.

Rig Performance Across Maya Versions

After coming off of a long project on Maya 2023, I'm attempting to upgrade to Maya 2027 and noticing that RRM3 seems to run a lot slower on the same rigs.

On latest 3.0.5 beta, create a standard biped template and generate the rig. Set the scene to 60 fps to give a lot of head room. Turn on FPS on the Display > Heads Up Display > Frame Rate. Keyframe the hip to translate around. In Maya 2023 I get ~30 fps. In Maya 2026 I get ~21 fps. In Maya 2027 I get ~18 fps. Those are the only three versions I've tested. Prefs are identical between all 3. I haven't investigated a whole lot yet as to why, except that it drastically speeds up without the NURBs controls rendering, and/or turning on curveManager in General Editors > Evaluation Toolkit > 04 Custom Evaluators. I would appreciate an…

Just updating anyone who may read, that I've been able to patch this to a satisfactory degree on my end in 2027, by making sure curveManager is checked on when a Rapid Rig file is in my scene. I put this code in my userSetup.py (disclaimer: AI generated) import maya.cmds as cmds

import maya.utils

def kickstart_curve_manager(*args):

# Verify the evaluator exists in this version of Maya

if "curveManager" in cmds.evaluator(query=True):

# Mimic the manual toggle to wake up the system

cmds.evaluator(name="curveManager", enable=False)

cmds.evaluator(name="curveManager", enable=True)

# Force the Evaluation Manager to rebuild the graph

cmds.evaluationManager(invalidate=True)

print("Success: curveManager kickstarted and graph rebuilt.")

def setup_curve_manager_jobs():

# 1. Run the kickstart once immediately after boot

kickstart_curve_manager()

# 2. Create a background listener that runs the kickstart every time a file is opened

cmds.scriptJob(event=['SceneOpened', kickstart_curve_manager], protected=True)

# Execute the setup only after Maya's core UI and engine have fully loaded

maya.utils.executeDeferred(setup_curve_manager_jobs) This drastically increases my FPS on Rapid Rigs. But as to the reason for why it's dropped in the first place, my educated guess is that Maya's under-the-hood rewrite of the Evaluation Graph doesn't like all the visibility conditions and the associated math nodes on all the NURBs curves.

Stalling at Generating Limb Controls

Hello! I'm having issues generating the rig from proxies, it gets stuck at 50% at the Generating Limb Controls step. It seems to be due to this error? # UnboundLocalError: cannot access local variable 'rot_offset' where it is not associated with a value

Full results from the script editor below: select -r asfMain_Ctrl ;

select -r RRM__Limb_Ankle ;

Quick Question about Scaling

I have a character that has an appendage that I need to scale uniformly when animating. I'm trying to avoid using blendshapes for this particular project, and wanted to see if there's a way to create a single scalable control using rapid rig? (basically an aux control that can scale the joint)

I built this smaller cube rig just as a tester example, with just a root and aux joint. As a work around, I found that I could just connect the scale attributes of the control curve and joint in the Connection Editor, but I know that's probably not the best practice and it would have to be reconnected for any rig rebuilds.

If building a scalable control isn't possible, is it possible to attach a custom joint and control to the rig itself after I've generated the rapid rig?

Thanks so much in advance for your help! 😊
