I am using big DN files, between 500 Mb and 1Gb. DN file because of high-res PSD decals.
I have started a new project using one of my current files, and I have deleted all objects to just keep the lighting, environment, and camera settings. When saving the DN files still weights the same MB amount. Even if I delete everything, the file doesn't decrease its size. It's like the DN file only adds information but it's unable to clean up what it's no longer needed.
Is this something normal, or the file should decrease its size when deleting objects, decals?
I did the same in another project. The project weights 1.2 GB. After deleting all objects, the resulting .DN document is 1.17 GB. It would be great if there is a way or is planned to add an "Optimize file size," "Reduce file size option. Do you have a plan to offer this feature?."
