Orthomosaic Processing Error "file used by another process"

PIX4Dmapper

Hi, I am running a project through Pix4d Mapper and am getting an error on step 3. This error is …3_dsm_ortho/2_mosaic/tiles/CWTP_ActivatedSludgeSite_250224_transparent_mosaic_group1_2_4.tif_tmp.tif: file used by other process
[Error]: Blending: failed to write tile!
[Error]: Generate orthomosaic [group1] failed!

I have tried shutting down the PC trying again with no luck. There is also plenty of space on the drive. I also deleted the ‘tiles’ folder and this deleted fine, so the files are being created new by Pix4d.

The project is not large, around 300 images.

Cheers
JC

I have now had this happen on a second job. "J:/_Drone Temp Locations/195 - Waitaki Wetland Opening/Pix4d/250226/Waitaki_Wetland_250226/3_dsm_ortho/2_mosaic/tiles/Waitaki_Wetland_250226_transparent_mosaic_group1_4_2.tif_tmp.tif: file used by other process
[Error]: Blending: failed to write tile!
[Error]: Generate orthomosaic [group1] failed!

Any help appreciated

Solved, should have started with this, but solution was “IT 101”, restart the PC.
