I made this coin and placed it on a Dutch F1 site. It is considered very beautiful. But now I want to make it running. Is this still a working file?

Yes it is a working file, but you DO NEED to clean the PNG export as PNG again AND uncheck the save color in alpha Attachment: screenshot_20211126-193229.png [ 42.24 KiB | Viewed 2811 times ] Your png was saved with "Save color value from transparent pixels" which interfere with G'MIC (and even GIMP as when you use the eraser tool in "anti-erase" mode you will see the background  -> Thus G'MIC will show you with its "3D extrusion" which will allow you to rotate (spin) it effect Attachment: screenshot_20211126-193831.png [ 732.32 KiB | Viewed 2810 times ] when cleaned rotate Y-angle by 1 degree and you got your gif (or mp4) Yes you do need to rotate 1 degree -> 360 times -> it's a lot but may be less if you rotate by 2 or 3 degrees, but you will have your spinning coin WITH the GOOD lighting  ( WAIT: -> I cannot try G'MIC -> Sequences/ 3D extrusion [animated], as I got an error, may be it's simpler as you can chose the number of frame if you do not have error )Attachment: screenshot_20211126-194646.png [ 581.42 KiB | Viewed 2810 times ] Although you can use a "normal map" (which IMVHO will do a better job about lights), but it's a lot more work.... Let's keep it simple (or use the normal map in Blender )

Thank you for your explanation... I'll get to work on it. But actually I was looking for a plugin (Ella spinning coin) that I did find on this site... but gives errors. I hoped there was an update for it. |

Hi Jappaloe, this is the tutorial: How to make a spinning coin without GAP. https://gimplearn.net/viewtopic.php?f=1 ... hilit=coin Animicule made a plugin of it. I think it was on Gimp Learn. If the plugin doesn't work you can make it by the tutorial. More work then

The plugin is here: https://www.gimplearn.net/viewtopic.php?f=3&t=790 It does work. Three layers needed. Front, Back, Edge. The Back layer flipped both vertically and horizontally The edge is not quite correct, plenty have used this plugin, advice please. Attachment: 3-layer.jpg [ 53.37 KiB | Viewed 2768 times ] It does scale the image and for an animation, delete the original layers at the bottom of the layer stack. Attachment: coin-spin.gif [ 815.61 KiB | Viewed 2768 times ] Sorry about that

G'mic animated Extrude 3-D works ok for this. I never used the plugin you mention though.

A bit more experiment. The edge layer should be rectangle as: Attachment: edge.jpg [ 36.28 KiB | Viewed 2757 times ] |

You can also run the BA Gold Coin plugin, leave the layers, and then run the spinning coin plugin to see how that works. It may take a while to render but it's worth a shot. |

I didn't read the tutorial, so lot's of trial and error. Looks like you need to make the edge layer with tight grooves space vertically to get the right effect. Since it's grey, you can colorize the layers if you want before running the script. Attachment: Coin-gold.gif [ 1.8 MiB | Viewed 1736 times ] |

After reading what goes into the spinning coin plugin, why not incorporate both tutorials into one and create the plugin that way. Also, when running Brian's coin plugin, the coin grooves are either very very faint or just nonexistent when "YES" is enabled on the grooves selection of the plugin. I'm running the current version of gimp on windows 10. |

Unfortunately for me, Brian's coin plugin doesn't work. I'm using GIMP 2.10.28 on Windows 10 and the spinning coin plugin seems too complicated. Why would the user need to use two tutorials for the spinning coin plugin to work? |
