How to Speed Up Bulk Mockup Processing

If Bulk Mockup Photoshop Plugin is taking too long to process your files, the bottleneck is usually Photoshop resources, large batch size, or disk space. This guide shows you how to speed up processing with the fixes already recommended across Bulk Mockup documentation and website guidance.

Before you begin: Bulk Mockup Photoshop Plugin works with Adobe Photoshop CC 2022 or later. If you are processing a large batch, keep at least 50 GB of free space available on the drive Photoshop uses for temporary files.

Step 1: Close other apps before you start

Before running Bulk Mockup Photoshop Plugin, close browsers, video editors, cloud sync tools, and any other heavy apps. This frees up RAM and disk activity for Photoshop, which helps large batches finish more smoothly.

This matters most when you are generating many mockups in one run or using large PSD templates.

Step 2: Check your Photoshop scratch disk

Photoshop creates temporary files while processing each mockup. If the scratch disk is nearly full, processing can slow down or stop with a scratch disk error.

  1. Open Photoshop.

  2. Go to Edit > Preferences > Scratch Disks on Windows, or Photoshop > Settings > Scratch Disks on Mac.

  3. Select a drive with more free space.

  4. Click OK.

  5. Restart Photoshop.

If possible, use an SSD as your scratch disk for better performance during large runs.

Step 3: Delete Photoshop temporary files

Old temporary files can take up the space Photoshop needs during processing. Clearing them helps when Bulk Mockup Photoshop Plugin slows down after several runs.

  1. Close Photoshop completely.

  2. Delete old Photoshop temp files from your computer.

  3. Reopen Photoshop and run your batch again.

  • Windows: Check C:\Users\[YourUsername]\AppData\Local\Temp for files that start with Photoshop Temp or pst.

  • Mac: Check /Users/[YourUsername]/Library/Caches/ for Adobe Photoshop cache folders.

Step 4: Use smaller batches

If you are trying to process hundreds of mockups at once, split the job into smaller groups. The Bulk Mockup troubleshooting guidance recommends working in batches of 50 to 100 instead of trying 500 or more in one run.

Smaller batches reduce scratch disk pressure, make errors easier to spot, and keep Photoshop from slowing down over time.

Step 5: Restart Photoshop between large runs

When you are processing many files, restart Photoshop every 100 to 200 mockups. This clears memory and temporary files that build up during long sessions.

This is one of the simplest ways to keep Bulk Mockup Photoshop Plugin processing consistently when working through a large design folder.

Step 6: Use Replace Content Resize when it fits your workflow

Bulk Mockup documentation recommends Replace Content Resize as a lower-disk-space option. This can help when disk usage is slowing your workflow.

Use Replace Content Resize only when all your design files have the same dimensions. If your files are mixed sizes, review your workflow before switching methods.

Step 7: Reduce Photoshop memory usage

Photoshop performance settings can affect how smoothly Bulk Mockup Photoshop Plugin runs.

  1. Go to Edit > Preferences > Performance.

  2. Set Let Photoshop Use to 70 to 85% of available RAM.

  3. Reduce History States to 10 to 20.

  4. Click OK and restart Photoshop.

These settings help Photoshop use memory more efficiently during large mockup runs.

Step 8: Review your mockup workflow

If your template uses linked smart objects, you may not need to enable multiple-smart-object processing for the same design. That can simplify the job and avoid unnecessary setup.

For more on that workflow, read Can multiple smart objects be replaced with the same design?.

Checkpoints while following the steps above:

  1. Scratch Disk settings: Capture the Photoshop Scratch Disks preferences window so readers can confirm the correct drive is selected.

  2. Performance settings: Capture the Photoshop Performance preferences window showing Let Photoshop Use and History States.

  3. Bulk Mockup panel: Capture the Bulk Mockup Photoshop Plugin panel with the folder fields for PSD Template Folder, Design Location, and Export Location.

  4. Completed export batch: Capture the export folder after a smaller batch finishes so readers can verify the run completed normally.

If you are adding screenshots later, annotate the settings or navigation readers need to click next. Do not annotate the final export results screen.
