Basically I upgraded to UE 5.1 and tried out the new MediaPlate feature. However, UE is not correctly displaying PNG image sequences. I would expect that when I set the blend mode for the media plate to Masked that it would hide the transparent pixels, however it is not and it is just showing a black square around it.
What is going on?
I’m currently attempting to uninstall UE 5.1 and reinstall and see if that fixes anything.
Thanks.
Hello! Having the same Problem! Ugh…
Hi, I did have a fix for this and I got PNG’s to work properly. But I actually just switched to using EXR files because they are better quality and easier to use compared to PNG. Let me know if you want me to get a video that helps you solve this. Thanks.
How did you fix it? I can’t get transparency to appear properly with media plate.
black square around the png sequence usually means the MediaPlate material is still on Masked or its opacity isnt actually wired to the alpha band of the PNGs, so the transparent pixels draw opaque. try switching the underlying material to Translucent and confirm the sequence was exported with real alpha (not just transparent viewer in photoshop but alpha channel in file). also check premultiplied vs straight. for a quick sanity check without fighting MediaPlate, i use alpha video player from fab Alpha Video Player - Transparent Video UMG Widget & UI Media Component (UE5) | Fab — it plays png/exr sequences with alpha correctly as a UMG widget (has alpha composite vs blend dropdowns), handy to verify the sequence itself is good before blaming the plate
