Also double checked with the 3D file viewer that it is not animated. One giveaway of the problem was that when rendering it renders the first frame for a minute or so and then jumps to 250 right away and finishes.

I was like, this time it did work but it generates a 800mb FBX with 250 frames, UE4 sees that it is animated but it doesn't actually move and is as if it was a single frame. So, before the OUT null I used a Pack node. I then tried to use the RBD to FBX node from the Game Dev shelf, learned that a geometry has to be packed after getting the error that the node I was trying to export is not a geometry. I picked the OUT node in my File 1 Geometry but it only generated a few bytes of file. Later on, I learned that in the /out context I also can create an Filmbox FBX Animation node and render it from there, as in the tutorial I simply do have a Geometry Node with everything happening inside and with an OUT null node at the very end. Though it creates an 8 byte FBX along with a xxxxx.fpc folder which I am not sure what to do with, I browsed a bit but was a dead end in terms of having a single FBX. Right now, I have tried to export it using the Animated FBX in File menu as it is the most direct and straightforward or seemingly straightforward option. Though I need the full 250 frame animation to be exported and be able to import to UE4, I have seen quite complex simulations can be transferred. Following this tutorial I could get it working with my own 3D file instead of the test_geometry and have the exactly same setup right now [ Though, when I render in alembic as in the tutorial the output file is around 80GB (yes) and I obviously can't import it to UE4 - I have tried smaller versions and it works perfectly. I know this should work on my licence version too so I desperately need help after days of work. I know there are tons of videos and tutorials on this but please believe me even after watching them all I still can't get it to work.

I recently took on learning Houdini and even after following my first tutorial I seem to be stuck in terms of getting an animated FBX output so I can place it in my UE4 project. Greetings, First post here and I'm very excited.
