I'm new here so I will do my best to cover all the details. To start I'm using two programs, Blender and Gimp. I used Gimp to set up the original images need to build a 3d coin in Blender, used Blender to build and render a 180 rotation of said coin, and went back to Gimp to export it as a gif. Everything has been smooth until I looked at the finished gif.


As you can see, it's exporting with white pixels all over it. What it should be looking like is this.


Once I got the frames from Blender on to Gimp, the only thing I did was use the Optimize for gifs filter on Gimp and the playback didn't show any of the white pixels. What can I do to fix this?

  • Hi. Welcome to GDSE. It's almost impossible to tell what has gone wrong here from the images you've shared. You've linked to a video, not a GIF. What was the original format? How did you get the frames into GIMP? What are your GIF export settings?

  • Those areas are not white... they are transparent. You can see here that they adjust to the background color. I'm not a Blender or Gimp user, but my guess would be you've got white set to be transparent somewhere, as opposed to merely a transparent background. (I'm not sure what "video link" @BillyKerr is referring to)

  • @Scott if that's so, then it might be something to do with original image format. If the original frames are in Indexed colour, that could easily mess everything up.

  • heh.. note the "here" link above.. will open on a black background in Chrome, making the transparency clearly visible when compared to the image here (on a white background). I just realized that some browsers may open the stand alone image also on a white background. Making my link seem pointless -- but it's not :)

  • @Scott - yeah I can see it now, wasn't working before for me. But is now. You're right, there's transparent pixels inside the coin. I can see it in Firefox with the Transparent Standalone Images plugin.

So for anyone following behind me, I found the solution that worked for me. The original format of the frames prior to trying to export as a GIF out of Gimp were PNGs that were placed in a tmp folder by Blender with the following setting as the output.

Blender Output Settings

I then used the Optimize (for GIf) filter that Gimp offers and exported as a Gif with the following settings.

What I ended up discovering is that if I skipped the Optimization (for Gifs) filter on Gimp, I got the correct and smooth looking Gif I was after. You can see what I mean at the following link. pretty not messed up gif
