Hi everybody, Id' like to understand why the 3D particles doesn't work. I am following the official tutorial and I just cant see anything.Il also like to know how to make an image shake with a target activate from a sound sensor. the effect I want to create is call wiggler in after effect.Thank you for your answer. Its for a class project.
Quite a big task... but doable.
Start simple. If you download the isadora examples then there is a scene all about 3D particles; which looks at rain/fire, etc. This will be a good starting point for you. Work backwards and just turn things off/on and see what it does.
Dont forget to look at the help files by alt clicking on the white text of the 3D particles also.
Lastly for the wiggle effect in AE youd need to use either an envelope generator linked to a sound level watcher or something like that. You will figure it out for sure.

are you generating particles with a z axis of 0 or a positive z? - in which case the particles will be generated, but you won't see them because they'll be behind the camera. or are you sending to stage or renderer? (2 things that sometimes catch me out...)

Hi, you can also use the 3D stage orientation actor and set the z-translate to a negative value. Say, you set it to -10 and click on the add object field on the 3d Particle actor, you will see the particle during the defined life span.
As for the movement of the particle, you need to check min and max of the parameters you want to use (x/y/z translate, x/y/z velocity etc.), and then create the particle movement within these min/max settings with the tools of your choice (experiment with manually with the mouse watcher,then use envelop generator, wave generator etc.). If you start with small min/max values (for example min:-2 max:2), you see the movement well.

Dear merkeuroney,I looked up the "wiggler" affect -- it sounds like you want to control the particles _after_ they are generated. The only control you have over that is the gravity x/y/z inputs. I've used the gravity inputs to simulate things like wind, but you might be able to get the particles to "wiggle" if you quickly send a series of random numbers into the gravity inputs, e.g.,Wave Generator (set to 'random') at 10Hz -> gravity xYou will need to set the 'scale min' and 'scale max' of the gravity input to get good results. (Click on the word 'gravity x' for instance to show the inspector box that allows you to do that.)You'll need to experiment with the scale min/max values to get the right range of response.Best Wishes,Mark
