AEM as a Cloud Service Dynamic Media: Multi-Axis Spin Set isn’t created when the preset regex includes a file extension

Last update: October 14, 2026

Adobe Experience Manager as a Cloud Service (AEMaaCS) with Dynamic Media Classic integration doesn’t create Multi-Axis Spin Sets when the Batch Set Preset regex includes a file extension. Dynamic Media evaluates asset names without file extensions, so the preset doesn’t match the assets or assemble the spin set. To resolve the issue, remove the file extension from the regex patterns and reprocess or upload the assets.

Description description

Environment

Adobe Experience Manager as a Cloud Service (AEMaaCS) with Dynamic Media Classic integration (all versions)

Issue/Symptoms

  • Multi-Axis Spin Sets aren’t created automatically using a Batch Set Preset in AEMaaCS Dynamic Media.

  • Asset synchronization to Dynamic Media Classic succeeds, and all images are visible in the Dynamic Media Classic Asset Library.

  • The Batch Set Preset configuration matches the documented naming convention, for example, _S_R_C.jpg for 2 rows × 24 columns, totaling 48 frames per SKU.

  • The preset is active, correctly assigned, and visible in both AEM and Dynamic Media Classic.

  • Reprocessing assets or uploading new assets doesn’t create a spin set.

  • No errors or warnings appear in the Dynamic Media job logs.

  • Manual grouping in Dynamic Media Classic works but doesn’t validate the preset.

  • No Multi-Axis Spin Set is created in the configured destination folder, even after confirming all other configuration aspects.

  • Example asset filenames:

    • TEST12345_S01_R01_C01.jpg
    • TEST12345_S01_R02_C24.jpg

Root cause

Dynamic Media evaluates asset names against Batch Set Preset regular expressions without file extensions. Including the file extension in the regex prevents the preset from matching the asset names, so no Multi-Axis Spin Set is assembled.

Resolution resolution

Follow the steps below to resolve the issue:

  1. Review the Batch Set Preset configuration in both AEM Assets and Dynamic Media Classic.
  2. Check the regular expressions in the Match, Row, and Column fields.
  3. If the regular expressions include a file extension, such as .jpg, remove it from the patterns in the Match, Row, and Column fields.
  4. For example, change the Match field to the following expression without .jpg at the end: [ a-zA-Z0-9] +_S[ 0-9] {2}_R[ 0-9] {2}_C[ 0-9] {2}
  5. Save the updated preset.
  6. Reprocess the assets or upload a new set of assets that matches the naming convention.
  7. Confirm that the Multi-Axis Spin Set is created in the configured destination folder.
