First post! And in my typical fashion, a bug report.
I'm using the Spriter Essentials Edition as I am testing the prog. I came upon this bug just a moment ago and wanted to know what I was doing wrong. When I discovered it was a bug, I did some tests and it seemed to be connected to the way files are named.
Consider the following.
-I have the following images:
/zumbug_idle_E.png
/zumbug_idle_N.png
/zumbug_idle_NE.png
/zumbug_idle_NW.png
/zumbug_idle_S.png
/zumbug_idle_SE.png
/zumbug_idle_SW.png
/zumbug_idle_W.png
-I set a custom pivot point via the File Palette for image 'zumbug_idle_E.png'
-I click the Copy Default Pivot Points button in the same palette.
-Multi-select the rest of my images, the Paste Default Pivot Points.
-The result:
/zumbug_idle_E.png - SOURCE COPY
/zumbug_idle_N.png - PASTE OK
/zumbug_idle_NE.png - PASTE NOT OK
/zumbug_idle_NW.png - PASTE NOT OK
/zumbug_idle_S.png - PASTE OK
/zumbug_idle_SE.png - PASTE NOT OK
/zumbug_idle_SW.png - PASTE NOT OK
/zumbug_idle_W.png - PASTE OK
-So I thought it might be something to do with the length of the string name of the image whose pivot was copied.
-So I copied the pivot of zumbug_idle_NE.png, and tried pasting that to zumbug_idle_NW.png. But it didn't paste the values, unfortunately.
-To further test the string-length idea, I created a two sprites in another folder:
/zumbug_idle_NE.png
/zumbug_idle_NW.png
-These do not copy/paste properly
-So rename them, they copy/paste ok:
/zumbug_NE.png - SOURCE COPY
/zumbug_NW.png - PASTE OK
-Then I add characters up to 12 characters, and they still copy/paste ok:
/zumbug____NE.png - SOURCE COPY
/zumbug____NW.png - PASTE OK
-But if I add one more '_', it stops working:
/zumbug_____NE.png - SOURCE COPY
/zumbug_____NW.png - PASTE NOT OK
-Note that the initial set of filenames (eg zumbug_idle_E.png) were already beyond 12 characters, but they still worked, so I don't really know if it's totally about string length.
-As a final workaround, I shortened my filenames completely:
/zumbug_01.png
/zumbug_02.png
/zumbug_03.png
/zumbug_04.png
/zumbug_05.png
/zumbug_06.png
/zumbug_07.png
/zumbug_08.png
-And using these images, the copy-paste pivot points operation worked ok.
I hope that helps you troubleshoot the issue.
