Let me begin by saying that I am also a huge fan of Particle Playground (there are not that many of us, probably because of the complexity of PP).
Regarding your suggestions, I am passing them along to the team. Bear in mind that Particle Playground was a deep research project untertaken by some brilliant AE team members 12 (yes, twelve) years ago. Because of this, for all the cooless in it... it's not easy to update. And It doesn't get along well with the simultaneous frame rendering model now in AE, ie given interframe dependencies it would be much slower it it attempted to use that, so when you use PP, AE disables multi-processing in order to not drown your computer Making it 3D? Pure speculation on my part, but PP seems so 2D at its' heart, that it could be easier to develop an entirely new 3D particle system someday, and add PP's "greatest hits" (like the property mapper idea) to that.
I will try your ephemeral property mapper issue later tonight (oddly, you named properties I rarely or never use) and if I see the same thing, I'll try (as always, no promises) to find out why.
those who don't like particle playground they should to the see the following examples
that I created some months ago.
and after watching try to do the same thing in other other particle
system then they understang the power of PP.

thanks for the quick response.
waiting for the solution. any idea will be appriciated.

Those are really excellent examples of the power in Particle Playground, Abhay! PP makes a few things more difficult than they are in other particle systems, but it's full of power inside. Believe it or not, I was going to ask if you had some examples to show your work with it. As I said, I have always been a fan of PP.
For example, the texture mapped in the front of this thing is all Particle Playground:
Regarding your question on those properties in the Ephemeral Property Mapper section, the person who I wanted to discuss this with is unfortunately (for us) out on vacation for a few days.
sorry for the late response.
My internet speed went terribly very slow.
so I was disappered for a while. but now everyting is fine.
I haven't done anyting special with PP riht now.
but actually I was planning for a tutorial dvd entirely for PP
I am working on that right now so, I definately I have to creat something
stunning. May be a mind blowing promo.
thanks for the comments.
wating for the solution.
A tutorial DVD on Particle Playground sounds like a great idea.
I'll try to have some information on this next week. As of now, yes, I can get all these properties to work as expected in the Persistent Property Mapper but not in the Ephemeral section.
I hope you get this message, considering the time since you first asked about this.
I just got an explanation and a sample project from one of the AE engineers who created Particle Playground.
At least in the specific case of using the gradient velocity property in the ephemeral property mapper (instead of the persistent section), the influence turns out to be so ephemeral indeed, that you may need to enable motion blur to see it at all. Seriously!
Here's the explanation from him:
The key is to enable motion blur -- since the speed is set only momentarily, it has no effect on the
position for this frame (because the order of operations has the position updated based on the speed, and then the speed updated based on the map), but you can visualize speed when motion blur is on.
In the attached project, try dragging the cannon start point vertically to
see how the dots are affected by the text map. Can be used for an
I hope this solves the mystery of the elusively ephemeral properties

Thanks a lot!
it's given me a lot more space to play with particle playground further!
