Hi,

What do I have to do to make the particles collide in the other objects in the scene? I seem to remember that I earlier used to make the objects static RBD objects, but now it doesnt seem to work. Im using the new pop network.

You must be doing something sloppy there, because it should work right off the bat,just by creating static objects.
Moreover, if it´s bounce what you´re after, rigids is the only way. POP collision nodes only work for other behaviours.

It should work without any problem. Check your collision shape generated in dops.

Hi,

The geo is wired through a static solver. Please see the attachment.

You are using volume based collision detection. As I suggested you to check collision shape in dop, it's not generating collision surface. May surface is too thin.
You can create your own volume at sop level then feed it in Poxy Volume parameter and change Mode to Volume Sample and adjust Division Size.

Or turn of Use Volume Based Collision Detection.
This way bullet based collision will be used.

Perfect! Thanks!

What would be a good expression to make the particles in this particular scene to rotate a bit?

When you want to rotate particles?

They are going to behave like this - https://www.youtube.com/watch?v=flro8QVDfn0 [youtube.com]

Use POP Torque DOP.

So no need of putting expressions in the particle rotate fields?

No need. But you can put if you wish.

And don't forget to add POP Drag Spin DOP to add spin resistance. Otherwise it might get crazy.
