Workaround in 4.23 (havent tested this in 4.24 but it may work as well): If you add your sequence to the level, set it to autoplay, then add a matinee and use the “movie” button in the top right of the matinee window to export, the play rate track works as intended. This has a few caveats though:
-There’s an odd quality to the motion blur.
-You can’t specify a frame range
-You cant add a burn-in to your video
-Matinee itself is going to be patched out any day now
Still it’s better than nothing. Epic, I can’t stress enough how important this functionality is for my current project. For the love of God please fix this! Alternatively, can you hold off removing matinee until this is fixed? My workaround, while not perfect, is better than nothing, and losing the play ate track entirely will have major consequences for my project, and probably others.
