I have a save animation that we are using an Image Sequence to play, but for some the Image Sequence asset breaks whenever I package the project or move it to another computer. The Image Sequence, Media Player/Texture, and Material are all stored within the Content/Movies folder, while all the pngs are stored in a subfolder (Content/Movies/SaveAnimation). To play the animation, I have the Media Player stored as a variable in a widget, and use the Open Source node for the Image Sequence. The animation is then played whenever a save is triggered.
The issue that I am having is that, whenever I either play in a packaged project or access it on a separate computer, I get a black box instead of my animation. The ImageSequence works in the editor on the computer I made it on, but if I open the editor on another computer or package the project on any computer, it no longer works. I can’t check with the packaged project, but on another computer the Image Seqence Asset breaks. I’ve tried purging the temporary files and letting Unreal recreate them, but it doesn’t fix it. Instead, I am met with a few warnings: “Warning: [AssetLog] insert path to the ImageSequence inside the project here VerifyImport: Failed to find script package for import object ‘Package /Script/ImgMedia’” and “Warning: Unable to load test with outer Package /Game/Movies/test because its class (ImgMediaSource) does not exist”, and an “Unable to edit Assets” error when I try to open the Image Sequence. I can fix this in the editor by right clicking on the Image Sequence and selecting “Reload”, but I have to do that every time and it remains a black square on package.
I’ve tried packaging/copying the movies separately, and listing the folder as a non-asset directory, but none of it fixes the issue with packaging. Does anyone know what might be causing this?
