Vector Field file

Hello,

What a nice work.
I have an issue with creating vector field. I suceed in creating the signed distance file with houdini but I have no idea how to create the distance gradient.

Could anyone help me ?

Thanks a lot.

.vf file format specs

Hello,
I would like to use the Houdini plugin to export vector fields in my personnal project, And I would like to know if there are any specs on the ".vf" file format, in order to create an importer (I'm not using Unity)

Thanks

Error when upgraded project

Hello,
When I upgraded this project to Unity v2020.3.12f1 I met issue:
"Library\PackageCache\[email protected]\Runtime\Volume\VolumeManager.cs(66,23): error CS0246: The type or namespace name 'Collider' could not be found (are you missing a using directive or an assembly reference?)"
Please help me fix it.
Thanks

Understanding the vector gradient

Hi,

I'm trying to recreate this without the use of Houdini.

Can you explain a bit more about the Distance Field Gradient file?

If I understand it correctly there are many possible gradient vectors for every point in a distance field. What is the gradient in relation to? A tangent on the surface? Or something else?

Animated meshes

Hello,

Have you an idea on how using an animated mesh with your VFX sample ?

Thank you !

Incompatible with python 3 Houdini

Unity-Technologies/VFXToolbox#26

I was able to generate SDF via Unity, but the houdini tools are now out of date, so I can't generate distance gradients, noise gradients, vector fields etc. to work with this package.

How to gen DistanceGradient.vf and NoiseGradient.vf?

Hi, I like your Great work! I learned use the Houdini to gen VF file, but how to gen DistanceGradient.vf and NoiseGradient.vf? Thank you very much!
