Vertex animation not working in Niagara particle system

Development Asset Creation FX

I am trying to create a Niagara particle rain system that uses collision events of raindrops to spawn mesh particles that are animated by a vertex animation texture but for some reason whenever I apply my material instance everything just stops working. It just loops the vertex animation over and over again and doesn’t recognize location rotation or anything really.

I know it has something to do with the way the VAT is influencing the world position offset of the mesh since when I use a non animated mesh it works perfectly fine.

example with normal static mesh:

Were you able to find a solution to this? I’ve been trying to figure out how to get my VAT liquid to work in Niagara but no dice so far!

I have the same problem, any solution?

Try setting the Max and Min bounds manually in the material instance. For me it was the issue (In Unreal 5). If you have a recent version of Houdini, you can access this info by exporting the Real-Time JSON File Legacy and importing it as a data table in Unreal.
