K-volume custom object

Post by simo_montru » Fri Mar 06, 2020 9:23 am

Hi

I didn't find any documentation on how to use a custom object for the k-volume.

Or, how to use multiple standard fields in k-volume and mix them

What I need is a kind of a bottle so a little cilinder + a cone + a bigger cilinder

Can anyone help me?

Thanks in advance

I don't know about the C4D version, but in the Stand Alone version of Real Flow, when you add a K-Volume daemon, there is an option to select a custom object.

Hi

in Cinema4D versions below 20 you could simply drag an object in a slot of the falloff, that was easy. Now, in 20+ you have to use fields, which is another layer of tools in between RF and Cinema4D. What you can do is this with any object with odd shapes (there are special shaped field such as for cubes, but this one works with all shapes)
1) create an RF scene with emitter and fluid
2) make an object that you would like to exclude particles
3) make a "volume" with this object inside, adjust borders by choosing the voxel size
4) make the k_volume daemon, go to the fields tab
5) create a new "volume" field with the volume object inside
6) use "invert" in the remapping tab of the volume field
7) test the particles, they should be killed by this object/field
