It’s kinda hard to see, but there is an image there, but It’s transparent. I finally was able to add a looping animation to this image sequence but it has no color at all.
Hello! Welcome to the forums!
Alpha is kind of notorious for being a pain. Do you need it at all, or is just a solid image sequence what you are looking for?
If it’s the latter, just unplug the alpha output from the image and set it to one in the BSDF.
If you want to use the alpha of the image sequence, you need to find out what kind of alpha it was saved with. This page from the manual is a good starting point for understanding what settings you need.
So, when I turn the alpha off the faint shape of the image turns into a square and still is transparent
