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?

    Try https://github.com/keijiro/VfxVatExample for unity option

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

  • Noboru_Garcia 1 year, 2 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.

      I have the same problem, did you resolve this issue?

    The dropbox link for the example files seems to have expired? could those be updated, please?

      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 But do be aware that this content was built with the original version of the tool and might be slightly out of date.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 9 months, 1 week 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.

    Grettings and thank you for all the amazing labs tools.

    I too am haveing problems with copying and pasting the material code in UE4. whe resultant shader has node floating in space, and the time node is not hooked up to anything. I am using labs version 18.5.408 on Houdini version 18.5.408.

    It woudl be great to get a video on how to build our own version of this shader to have a fall back on when the automated stuff dosn't work or is not feasable to use. While he network is not compelx to the person who designed it, as an end user opening that refrigereator door is quite overwhelming.

    Thank again for all the great tools!
