Because of licencing, I’m considering moving a project of mine from Unity to UE4. There’s one thing keeping me from doing that, though: all my HUD elements are pre-rendered image sequences that are then mapped onto spheres. As far as I can tell, UE4 doesn’t have any way to play a movie on a texture (due to the removal of Bink). Sprite sheets / flipbooks aren’t an option, because some of these sequences have a pretty high resolution (720p).
Is there a workaround for achieving this? Could I, say, put an image sequence in a directory and have the engine cycle the texture 12 times per second? Or would the engine choke trying to constantly bring these images in and out of memory (especially if I’m doing this with 5 or 6 sequences at once)?
If it’s on the roadmap, does that mean it’s a feature we should expect relatively soon? As in, would it be safe to start a project that would need this feature eventually, or is there a that we won’t see the feature for half a year (or never at all)? I noticed it says July/August, but I don’t know if that’s an ETA.
Those time frames are our best guess, and is actively writing code for it. I would expect it in 4.4, or 4.5 if there’s a schedule upset. So some time in the next 12 weeks, but more likely around 6 weeks from nowish when 4.4 comes out.
