When using PPI, sometimes you may want to come back to a project later, and so it's important take some precautions to make sure you hold on to your PPI licenses for your images. Here are some tips to make sure you do not lose your PPI licenses.
- Always save your licenses locally - there are many reasons to save the license locally. It will not expire and we only keep your licenses on our servers for 2 years, this way you can keep them forever. You can use the licenses offline. You do not have to wait for RC to fetch the licenses from our servers.
- Wait for RC to fetch the licenses from our servers - sometimes it helps to disable/enable one image to see if the "L" appears. Fetching licenses on very large projects can take up to 15minutes.
- Don't edit the images - You cannot make any changes at all to the images.
- Don't re-process the images - you cannot re-create your images, even if you make them in the exact same way as you originally made them, even if every pixel is identical they will not be licensed.
- Don't changed the exif data of the images - you cannot mark, tag or otherwise change the exif data of your images in any kind of software that will organize your images, this will change the exif data and the license will not work on them.
- Don't delete any images used or unused that are inputs listed in a PPI project - Your PPI projects will not work if RC cannot find any of the inputs in their original state
- Keep your original .lsp files - if you bring an e57 or .ptx file into RC, RC will make .lsp files from them. It is these specific .lsp files that are licensed, so keep hold of them, and if you need to make a new project using the same laser scans only import these .lsp files. If you bring your .e57 or .ptx files into a new project RC will make new unlicensed .lsp files.
Although it will not preserve your licenses, you may want to save a checksum of all of your inputs, so if anything goes wrong with your project you can check at a later date which inputs have been altered, to help salvage what you can from a project. To do this open your images in Total Commander, and in the "files" menu select "create checksum file/s, then save the sfv file, and then you can later use this file to see if any changes have been made to your files and if so which ones.
