Seconding the chap above me would love an example .hip file.
Hi, Osgrim
The link is the .hip file I was used to test the velocity field exporter. hope it helps. Sorry about the late reply. Have a good day and let me know if you have any questions.
Hey there !
Sorry to be here that late but the Velocity Grid Exporter does not work on particle simulation in H15. I don’t know why, I look through code but I can’t see what’s the problem.
Hi !
I was trying to do some Vector Field or Velocity Grid for Unreal.
That’s an amazing tool but it doesn’t work on H15.5 with Particle Simulation. I don’t know why, I tried to look through your code, but I can’t see what’s wrong.
After many researchs in your code, and after looking at the debug node, I found that when you’re doing a Particle Simulation, the box is really small and don’t take the Voxel value in the interface. I fixed that problem but simulation doesn’t work even after that.
Do I make a mistake in using it ? Is there another solution to export Vector Field or Velocity Grid to Unreal ?
Any help is welcome !
Cheers,
Gaël.
Maybe a little late, but I thought I’d chime in here. A pop sim doesn’t create a velocity field by default. Theoretically you could create your own using a gas field vop and sampling the the particle velocity there, you would first have to manually create a vector field to sample to as well.
This exporter error in houdini 16 ;D… Do you have an upgrade version?
