Export simulation data to texture files. This allows for very effective vertex shader playback of your high resolution simulation. 

There are 4 types of simulation supported

  • Consistent Topology throughout the Simulation (Soft) 
  • Packed Primitive style Rigid Body Simulation (Rigid) 
  • Changing Topology throughout the Simulation (Fluid) 
  • Camera facing cards, points moving through space (Sprite)

    does unity get the same support?

    for the camera facing cards bake,
    is there any way to bake things like
    alpha, or orientation of the point?

    trying to find a method to bake a particle sequence in unreal that is controlled with unreal engine's 'time' node only for sequencer
    like a particle cache with a seek function

    The download file link is broken, any place I could get the support files to follow along?

    Hi luiz!
    How does the explosion material made by Houdini follow vertex animation to import Unreal?

  • Noboru_Garcia 11 months ago  | 

    Version 18 Labs tools are not generating a working material script. I have used previous versions and this one is not working in Unreal 4.24 with Houdini 18.0.327 and the latest versions of Labs Game tools.

      Also seeing this. Would be ace to get it updated really want to test my first sim.

      Updated, sorry about that. But do be aware that this content was built with the original version of the tool and might be slightly out of date.

    Hi Mr. Ikruel, where can I export the normal map for the setup of cloth and other objects with the last update of the vertex animation node? Anything changed since your video?

    • lkruel 5 months, 3 weeks ago  | 

      normal maps are a bit tricky, because you'll also need to export a tangent map alongside the normals map to get the normal maps to work properly, you'll also need to do a lot of the math yourself to convert from tangent to world space and then set your material to the world space normals.
