Frequently Asked Questions

How can I rescue a PTG painting that won’t open in ArtRage?

If you receive an error message and are unable to open a PTG file, then it probably means that your ArtRage painting was were corrupted at some point. Damaged PTG files usually result from interrupted saves (for example, if the computer shuts down or ArtRage crashes). We will do our best to help troubleshoot the source of ArtRage errors, but usually cannot fix corrupted or partial files.

However, if you can see the image thumbnail then that means that the PNG preview image is intact. If you use File > Import Image File to open the damaged files, then it will import the PNG thumbnail.

This PNG file is the full size of your painting and high quality. It won’t rescue your layers or other paint information, but it will give you something to work with.

Backup Save Files

If crashes happen frequently for any reason, or you are working on an important painting, we recommend turning on the Store Backup Files option. You can find it by going to Edit > ArtRage Preferences > Advanced > Store Backup Files.

Adjust the slider to the number of backups you would like to keep.

Important: This function does not save a duplicate file. Instead, it keeps a history of previous saved versions.

Every time you save, it will delete the oldest backup file, and save the latest changes as a separate file, so if you have made important changes, save twice to update the older back up and the file you are actually working on.

Why can’t I upload painting files to the internet or open it in other programs?

If you wish to upload an ArtRage painting to Facebook, DeviantART, Flickr, or any other website, or open it with other programs like Photoshop, Gimp or MSPaint, then you need to export your painting.

ArtRage uses the proprietary PTG format. This cannot be read by any other program. To create a JPEG, PSD, BMP, TIFF, GIF or PNG file, you need to go to:

File > Export As Image

Why Does ArtRage Do This?

ArtRage does not give you the option to save in different formats because the ArtRage PTG file is the only one capable of saving all of the media information for your painting. If you were to accidentally “save” your painting as a JPEG (for example), then you would lose layers, transparency, paint wetness, paint thickness, lighting direction, and canvas texture, as well as any attached References, Tracing Images, Color Samples or other ArtRage specific features.

However, because you still need to use your paintings in other programs, it gives you a choice of formats to use to export a copy of your painting.
