I am currently creating a custom python script for maya 2023 that imports usd files that contain animation. The issue im having is my script is importing the contents of the usd without any animation present. When i toggle the function in maya the only script editor feedback I get is mayaUsdTranslatorImport_AnimationCB; mayaUsdTranslatorImport_AnimationCB; for both on and off Here is what I have tried so far to turn on the import USD > Animation > Animation Data settings. def import_usd_with_animation(usd_file): """Imports USD file with animation using MEL to ensure animation options are set.""" if not usd_file or not os.path.exists(usd_file): cmds.warning("Invalid USD file path.") return False # Get file basename for namespace file_basename = os.path.basename(usd_file).split('.')[0] # Create a secure string representation of the file path for MEL usd_file_mel = usd_file.replace('\\', '/') # First set the option vars that control USD import behavior try: # Set required optionVars for animation import mel.eval('optionVar -iv "mayaUsdTranslatorImport_AnimationCB" 1;') mel.eval('optionVar -iv "mayaUsdTranslator_ReadAnimDataCB" 1;') # Verify options are set anim_cb = mel.eval('optionVar -q "mayaUsdTranslatorImport_AnimationCB";') read_anim_cb = mel.eval('optionVar -q "mayaUsdTranslator_ReadAnimDataCB";') print(f"Animation checkbox: {anim_cb}, Read Animation Data: {read_anim_cb}") # Method 1: Use MEL command to ensure animation is imported import_cmd = f''' // Set import options first optionVar -iv "mayaUsdTranslatorImport_AnimationCB" 1; optionVar -iv "mayaUsdTranslator_ReadAnimDataCB" 1; // Create options string with animation enabled string $options = "Animation=1;ReadAnimData=1"; // Import the file with options file -import -type "USD Import" -options $options -namespace "{file_basename}" "{usd_file_mel}"; ''' print("\nExecuting import with animation...") mel.eval(import_cmd) print("USD file imported with animation.") # Check if import was successful by looking for nodes with the namespace imported_nodes = cmds.ls(f"{file_basename}:*") if imported_nodes: print(f"Found {len(imported_nodes)} imported nodes with namespace {file_basename}") return True else: print("No nodes found with expected namespace, trying alternative method...") # Method 2: Alternative approach - for Maya 2023 specifically # Try a different way to force animation import fallback_cmd = f''' // Set additional optionVars that might be used in Maya 2023 optionVar -iv "usdReadAnimations" 1; optionVar -iv "mayaUsdImport_ReadAnimData" 1; // Import with specific options for Maya 2023 file -import -type "USD Import" -options "Animation=1;ReadAnimData=1;ImportUSDZTextures=1;" -namespace "{file_basename}" "{usd_file_mel}"; ''' print("Trying fallback method for Maya 2023...") mel.eval(fallback_cmd) # Check again for imported nodes imported_nodes = cmds.ls(f"{file_basename}:*") if imported_nodes: print(f"Fallback method successful.
