Frequently Asked Questions

A Radiance HDR file often stores lighting information for 3D scenes. A low-dynamic-range preview cannot replace the lighting map.

Identify the Missing HDR images

Confirm whether the original file was deleted, moved, replaced or merely inaccessible. Search by filename and .hdr extension in the folder where it was last saved. If the file still exists but fails to open, make a copy and investigate damage; a deleted-file scan alone will not repair it.

Check the 3D asset folder, cloud copy and source render before scanning. A backup or re-download may be more complete than a recovered fragment. If only a preview or converted copy survives, keep it for comparison but do not assume it is the same as the original.

Check Copies and Protect the Drive

Look in the Recycle Bin, File History, cloud version history and any application-specific backup. Note the original storage device and approximate deletion time. Copy surviving candidates to a safe location before testing them.

Avoid downloads, exports or new recordings on the affected drive. Save results to a separate physical disk. Deleted data can be overwritten by new writes, and SSD TRIM may clear deleted blocks. A scan cannot guarantee success, especially when the source is failing or the file was never fully saved.

Recover with Qiling Deep Data Recovery

Qiling Deep Data Recovery scans Windows-visible storage for deleted local files. First identify the actual source; scanning the wrong disk or a cloud-only account will not find the original.

Step 1. Prepare the Source

Close programs that write to the affected disk. Identify the original folder, device capacity and any related files. Prepare another physical drive with enough space for the recovered candidates.

Step 2. Choose a Scan Mode

Use Fast Scan for a recent local deletion or Recycle Bin Scan if the bin was emptied. Use USB/SD Scan when the file was on removable storage. If the first pass does not find the file and the device is stable, use the deeper scan option in the results.

Step 3. Select the Original Drive

Match the source by drive letter, model and capacity. Select the disk that held the missing .hdr, not the destination where you plan to save it. Start the scan and leave the source unused.

Step 4. Compare Candidates

Search for .hdr and compare names, sizes, dates and likely folders. Keep more than one plausible version. A matching filename or preview is not proof that the entire file is intact.

Step 5. Save and Test Elsewhere

Select the best candidates, click Recover, and save them to a different physical drive. Keep those files unchanged; test copies in a compatible application.

Verify the Result

Load the recovered environment map and check its full panorama, exposure and seam.

If one copy is incomplete, compare older versions and backups before attempting repairs. A changed file extension does not rebuild missing data. Once a result is confirmed, back up both the original-format file and any required companion assets.

Frequently Asked Questions

Can a low-resolution panorama replace an HDR environment map?

It may be useful for reference but may not retain lighting range or enough resolution.

What should I check after loading the recovered HDR?

Inspect the panorama seam and lighting result in the original 3D scene.

Where should I save the recovered file?

Use a different physical drive so the recovery output cannot overwrite other deleted data on the source.
