Nope, can’t do. Particular will always allign the custom particles towards the camera. Depending on the nuber of particles involved, you may wanna consider other options such as using expressions to build a custom particle system.

[Colin Braley] “Mylenium,
I’m just trying to share what I know. While this expression may have been a bit complicated for a beginner to understand, I assume others who read this thread will be able to look through it and figure out the code and maybe learn something. And in Ken’s case, he got a quick and easy solution even if he doesn’t feel like reading through all the code and figuring it out.”

Please, no need to apologize. You guys are great (but still a bit crazy ;-D) it’s just that my own rule of thumb is: keep it simple. Using loops, conditional statements and string methods certainly does not fall into that category. You know, the danger is that with such complex stuff you can easily put off people from ever using expressions again (out of frustration of not understanding the code)and that can’t be what we want when we should be convincing them of the exact opposite.

Huh? You just choose “RGB + Alpha” on the Output module settings and choose a file format that can handle it. That’s it. The rendered file will still show you the black background if you view it standalone, though, since in computer graphics there is no real transparency. Alpha channels only determine how the background info is used and you should be able to do just that once you import your stuff in Flash.

Transparency preview (checkerboard pattern as in Photoshop) while working (it’s one of the little switches on the lower edge of the composition window), Export with Alpha channel when rendering (e.g. PNG 24).

Whoa, you guys are crazy ;o). If I asked my mom (she’s a teacher) she’d probably say that this is against all rules of didactics and teaching methodology.

[echo] “Do I use the Math.abs function for this?”

I wouldn’t because it could cause unwanted stuttering and flipping in your animation. The easiest way is to add a value to the wiggle (which would be the average point around which everything wiggles). Animate your layer and then ad the wiggle afterwards:

my_wiggle=wiggle(3,5);

X=position[0]+wiggle[0];
Y=position[1]+wiggle[1];

[X,Y]

You can also further limit the values using clamp() or using conditional statments in combination with keyframe methods, something, I believe, you will find the code for in a posting not so long ago by someone else.

I forgot – layers can be offset using their index. So assuming your red solid is layer 1 (the topmost), all other layers can be offset using this:

thisComp.layer(1).position.valueAtTime(time + framesToTime(5)*(index-1)
