Houdini Data Interface for UE4's Niagara




Hi folks,

We’re getting closer to an official release of the Houdini plugin for Niagara. I’d love to get some feedback on the tools and suggestions for improvements. I’ll use this thread to post example files and videos for anyone interested in testing this stuff out.

[EDIT] Just a quick note. Change your file extension to hcsv instead of csv or you’ll get a window popping up at import time in ue4 asking what kind of data table the file is. [/EDIT]

You will need to download the latest gamedev tools to access the extra nodes in Houdini.

The plugin comes with the latest preview release of UE4 - 4.20 preview 3

https://vimeo.com/276145729/ad5f1dc611 - There are currently 5 content examples available with the plugin. This video will give you a run down of what’s going on.

There are 2 example files. niagara_examples.hip includes the setups used in the content examples.
niagara_destruction_example.hip is a basic rbd setup using some gamedev tools to simplify the rbd workflow.



Thanks! Definitely going to play around with it. SO much potential in a Houdini + Niagara combo.


This is fantastic! Thank you, Mike.


We’re really excited to see what the community does with this combo of tools, definitely post links.


Awesome! Thanks Mike!


good~. thanks.
Can Niagra assign particles for every fractal chunks?


I’m sorry. I don’t understand the question. Can you try rephrasing it?


the question is…
is it possible to attach a particle effect to a broken piece?

In Unreal, I created this because I could not attach particles to the chunks of the Fracture Mesh by default.
Please see this post below for more details.


You could use the interpolate export method which will give you a position that you could attach a particle system to. It would be similar to a socket on a skeletal mesh. Or attaching a particle system directly to a bone. But this would be for cached simulations. If your question is specific to Niagara I’d ask Shaun or Wyeth over in the Niagara thread. Niagara / unreal GDC


this is cached simulations in Houdini.
thanks for the reply.
