Hi,

I have some chunks thrown from a grid source. I also want particles to emit from the same source.
I have no idea what I have done wrong but I have attached my project file if someone can point me in the right direction.

Thanks!

All the best, Stig

Do you wanna generate particles from each Chunk !? :?
If yes,I think easier way is to use “Old Particle System” ! 8)
Just check Attached File :

Thank you.
That was actually pretty cool, but I want to emit the particles from the grid. The same grid as the chunks get thrown from.
And I want to do it with the new particle system if possible.
Any idea?

So you can simply define the grid's path (../../grid/grid2) to the “Object Merge SOP” in the geo_pop ! :?

sorry… when opening the project (that I posted yesterday) it all suddenly worked. I dont know why the particles didnt emit yesterday.
Thank you Joker. You are always a good helper!

:roll:

But… an another thing…
Where is the old collide sop? I want these particles to collide with the ground plane but I really cant find the collision sop, or now - the pop.

It's available in the “POP Network - Old” in the H13 ,Because you don't need to this node in the New Particle System ,Check my attached file from last post

Hi,

Its not necessary because the chunks colide.
But as you can see in the attached projects, the chunks collides with the ground plane, but the particles emitted from the same source totally ignore the ground plane.

Hey ,“POP Collision Detect” is pretty like to “Collision POP” in the Old Particle System ,So you have to define SOP object for it ,But you defined “Ground Plane” Dynamic object for it !!!

to solve that you have 2 way :

1. create another Grid SOP that using in the “POP Collision Detect”
2. create or Reference Copy from “Ground Plane DOP” from the original AutoDopNetwork in the Particles DOP Network !

Check Attached FIle :

If you attend to “POP Collision Detect” parameters ,It's tell “SOP Path” ,So if you wanna use DOP Object ,You should set this parameter to DOP Objects :idea:

How could I miss that! Thank you!!

That's no problem my friend

Hi,

One more thing:
What do you need the ground plane in pop (dop) for, when the string used in the pop collision detect is for a sop - “../../../JK_Ground/grid1”?

Shouldnt it be enough to have the pop collision detect string to the grid in sop without having to use the ground plane in dops?

Or make a ground plane in dops and refer to that in the pop collision detect? I see that DOP is an option in the collision target.


Stig

I think for general collisions like Ground collision, it is better to use ground plane DOP ,I think the processing for this way is faster than second way (create a grid SOP and make it as Static Object)

Also the Ground plane has infinity size on all direction ,So I think the better way is to use ground Plane :?

Hi again,

If I choose to use the pop collision detect and set the collision target to DOP.
What am I supposed to write in the “dop objects”-area?
Are they looking for a string, or what? My ground plane is in a DOP network.
