FLIP - Transfering Normal Data to Particles

[gramx]

Hi

Stuck! I am doing a test where I have exported the whitewater spray to a bgeo cache. I am then reading it back in and using a particlefluidsurface to mesh it. I am trying to use attribute copy to copy the normals from the mesh onto the particles. Not working yet! I want to read the closest point to surface and add the normal direction to the attributes of the particle so that I can then render particles with surface normals in krakatoa. I am exporting PRT.

I also want to do the same thing to the particles of a flip fluid.

Thanks for any help.

Attribute Copy only does it by point number. If you want by proximity you should use Attribute Transfer.

Thanks, I will give that a try!

OR you can transfer any attibute you want through VOP SOP point cloud.It will give you much more control if you need it and I think it will work faster than attribute transfer sop.Attached scene file.

I've got it working with the Attribute transfer there are some good examples in the help!

Thanks for the hip file Filipp I will take a look at that, a bit of extra speed will be a good thing when I try it with 20million particles!

Thanks for help!
