Oh you’re exporting the particles and not the mesh file. Try exporting our the mesh instead of the particles. If you want to export the particles you will need to use Blender to instance objects on the particles using geometry nodes.
Okay yeah I’m struggling as well, for some reason blender is just not adding any geometry to the alembic export. All my alembics are 2kb and I don’t know why that is. Might need to do some digging on the Blender side of things to see what’s up. The mesh export does work so you can use that for now if you want to move forward with your project that way, but I don’t know what’s causing this to happen in blender
Hi, not sure if it would work with you, but in my case I did exactly the same, but crop the firsts frames on the export in blender. After reviewing A TON of tutorials, they said that if the first frames are empty it wouldn’t work.
So, i did this=
Export particles from Liquigen (in my case just the spray for the test)
Import them in blender
Did the instance from points (with the realize instances node at the end)
Export the allembic from blender (starting from frame 3 in my case, you should see when appears your first geometry, it may be more)
Import in UE 5.4 (geometry cache, leaving the rest as it comes, starting in “frame 0”
And it works, the only problem is that the allembic file from blender obviusly is really heavy (50 Gb for 150 frames), but i’m sure it can be optimized.
