I've encountered this problem before, but decided to try a tutorial out thinking maybe it was a problem with the previous version, so what I'm doing is making a cube with 3 different 150 x 150 px pictures on the sides (obviously 2 pics each for the requisite number of cube faces), then once I've made the cube (using the normal Filters>Map>Map Object tool) I then duplicate the image about 40 times and go to the Filter All Layers dialogue where I choose 'plug-in-map-object' and 'Apply Varying' to get the object to look like it's moving along the Y-axis from a -180 degree all the way to +180 degrees.
Instead of that though the plug-in just alters the first and last layer and leaves everything else as it was. I tried doing a sphere but the same thing happened. Weird because all the other plug-ins work fine in Filter all Layers.. I'm wondering if anyone else has this problem and whether anyone knows of a possible solution, bearing in mind it happened in 2.8.18 also?

Thanks.

Yes the GAP one that's right, ok nice one I'll try the other GAP see what happens and get back to you.. Thanks a lot.

Didn't work, unfortunately. I've re-installed the 2.6 GAP, tried it again but same problem. I was copying the guy in this video -


The process he starts with the GAP Filter all Layers plug-in is at 4 minutes 15 sec.. I followed the instructions to a tee but didn't get the results shown in the vid.

Seems odd - I wonder what the problem could be?

Not working for me either Graechan. Thanks for the GAP-2.7 files though.

Graechan do you have a 64 bit old GIMP-2.6 Map_Object plug-in you can share?

Yes that worked. Thank you Graechan. I will post the results when the map-object filter is finished running all the layers.
Excellent!

On a side note i wonder if there is already a zipped package of these two together.
GAP-2.7
Map-Object-2.6

1) I placed the GAP-2.7 executables and dll files in their own sub-folder named GAP in c:\Users\Rod\.gimp-2.8\plug-ins
2) I placed Graechans Map-Object executable in the c:\Users\Rod\.gimp-2.8\plug-ins folder
3) I started GIMP-2.8 and pointed Edit>Preferences>Folders>Plug-ins to the GAP folder and restarted GIMP-2.8.

I ran the tutorial as on YouTube and it works fine for me now.

Well I never.. you live and learn! Looks like I'm going to have to try this myself ..

Cheers

Not sure what to do about the jaggies on the images though. Maybe fix each layer before exporting to GIF.
You could do this by using a path that is closed and create a selection from it. Then select invert delete. That could use a script itself.

Weird, i did everything you listed out to do, Rod, but to no avail.. still doesn't work. Oh well maybe it's to do with my installation, though I can't see how.. Hmm.. well no doubt there are other ways of achieving the same result so I'll look into those, thanks for your help Rod and Graechan.

Edit: Did I have to delete the GAP plug-ins from the Program Files/GIMP2/lib/plug-ins folder?

I would remove them yes.

Jaggies come from the "binary" transparency of GIF. The only way to avoid them is to use "Layers>Transparency>Semi-flatten" on all of them, but this assumes you know the background color.
