Any suggestions on setting up a sim for animation on 2s (24fps)? Everything works fine if the camera has no parallax (I delete every other frame). Although, if the camera moves (on 1s) that process doesn’t work since the frame stride is at 3 (72 Hz) and and frames group 3 on 3 off. I’m trying at 24Hz, but the timing isn’t lining up.
Hey can you provide the EmberGen and imported mesh files you’re using? In general, As long as you have these 3 values (Override FPS, Frame Stride, Timestep) that together make a sound / correct equation then you should only need to export the total number of frames that you have in your animated mesh. The examples in the image demonstrate different iterations that should all work the same.
To clarify, when you enable the Override FPS setting in your import node, parameter values of 60x1=60 or even 30x3=90 will still match 1 to 1 in a 24 FPS blender or UE project. (Override FPS x Frame Stride = Timestep)
Utilizing this, you should be able to just export the total number of frames need and they should sync up to your animation 1 to 1. Using this technique allows you a bit more freedom to experiment in EmberGen. If you have any questions about this please let me know!
Thanks for the reply!
I’m currently using 24X3=72 Hz, render out to PNG, composited in Blender, but if I use all frames, I get a weird misalignment. I’ll send of the alembic and the EmberGen file in a minute.
I think I got it now. I kept trying to do a multiple of 24, but I guess 1) the original FPS doesn’t matter much since you check override and 2) and it needs to be a multiple of 1 for stepped animation? Anytime the time step is other than 1, it almost looks like an inbetween is being added. Not sure I fully understand, but it works exactly like you said (no need to delete every other frame and duplicate). Thanks again!!

Awesome, I’m glad you were able to get this working. I’m definitely new to these kind of animation files going through EmberGen so I appreciate you sharing your files and keeping us updated!
