How to transmit the color per particle property after the simulate particle node ?

1. I have imported particles inside Bifrost (convert_objects_arrays_to_points). I have got color property in the out port?.

2 These go through the simulate particles, but I lost track of this color property. Now the result as an output are grey particles.

How can I transmit forward this color information ?

Thanks

Fransua

Hi!

1. I recommend to work in the main graph and not in the second graph created for particle import.

2. Insert a source_particles node before the simulate_particles node.

3. Add "color" as additional property to the source_particles node (additional properties).

Thanks Mspeer. It works great.

I also tried to replace simulate_particles with simulate_mpm, buit in this case nothing comes to screen, even if i plug source_mpm_sand instead of source_particles

Hi!

 

For mpm the setup is the same, however as source you need a source_mpm node with the additional property "color" added and the simulate_mpm node needs to be connected to an output.

Hi, 

So I too am working on relearning this technique using the Bifrost graph, but alas I am stuck. I've attached my Bifrost Graph Editor. Any help would be greatly appreciated. I am still learning the Bifrost system but I do have a bit of experience in node-based programming.
