I'm wondering how to use the switch node in conjunction with the collision node? I would like the particle to switch from being a point to a instance geometry when the collision happens.
Perhaps I'm trying out the wrong thing here, but I though that I could use the ‘collision’ nodes ‘hit’ as a trigger to switch the index.
Anyhow, a bit lost and would appreciate some help on my way.
Are you using the instance POP to get the geometry instanced or are you trying to instance the geometry at SOP level using a Copy SOP? I usually prefer the later but if your trying with a instance POP then try the following approach:
Make the collision POP add an attribute to the particles which has collided. Create a group from the collided particles. Instance the geometry onto that group.
And if you want to do it at SOP level with a Copy SOP (which I prefer), just skip the instance POP and pipe the POP Network into a Copy SOP and and enter your group name in the Template Group parameter.
