Animated Point Cloud Visualization


I’ve got a sequence of PLY files each with a different point cloud.

Using this tutorial:

I am able to visualize the point clouds with a particle emitter.

It works great in the viewport - each frame looks different.
However when I start to render all the frames look the same.

I’ve found out that the cache of the emitter keeps only one frame. I can’t bake the whole simulation.
Probably because each frame is actually a different object?

One option would be to somehow force the cache to cover my whole animation.
Another could be to force the renderer to repeat the simulation before rendering each frame - just like it works in the viewport.

I’m totally new to Blender so I don’t know if any of these options are possible.

Any help would be appreciated.
