Simple utility to create a decal extension from all images in a selected folder:
Attachment 26239
Use the "Desktop: decal image" option to select a decal:
Attachment 26240
Note: this creates the extension as a folder in the extensions folder, not as an .ext file. (You can manually zip the folder (from inside the folder) and rename to .ext if needed.)
Also, see this post for Wintermute 's Decal Maker if you want a lot more control over the decals and resulting extension: https://www.fantasygrounds.com/forum...read.php?47848
Thanks to Wintermute for the idea from the Background Theme Maker: https://www.fantasygrounds.com/forum...read.php?47787. Use that if you want to change the full background instead of using decals.
