Here are some of the latest tricks I have been playing around with, especially useful with Particular.
Tip: Add a ‘layer for motion’ selector for your particular emitter and make your keyframing easier.
Add an Effects>Expression Controls>Layer Control to the layer and name it ‘layerForMotion’
Add these expressions to the particular emmitter properties:
In Position XY:
In Position Z:
Now just select the layer that you want to control the emmitter. Be sure to convert that layer to 3D before selecting.
Tip:Adjust the amount of particles emitted based on the velocity (speed) of the emitter.
[UPDATE - also, have it stop emitting when it stops. No need to keyframe '0' ]
This is helpful when you get thin or clumpy areas of particles when you are moving your emitter at various speeds.
Add the following expression to the Particular ‘particles/sec’ property:
//specify the where the motion for the emitter is coming from
//get the magnitude of the position change (ie speed) and combine with attribute value you set or keyframed
//omit this if you don’t what it to stop emitting when it stops moving
0; //stop emitting if no change in position
Now you will get a nice even stream no matter how you zip the emitter around, and it will stop emitting when standing still so no more clusters!
Can’t remember the process for succesfully getting Maya camera and locators into AfterEffects? Here’s what I’ve written down so I won’t forget…
Maya scenes need to be transformed in order to appear in AE default space (where center is 960,540):
Scale = 100
TX = 960
TY = -540
How Cameras relate…
Default AE 50mm camera = Maya 50mm with Z = 26.6666
Default AE 35mm camera = Maya 35mm with Z = 18.6666
So, for basic setup create a Maya 35mm camera at z = 18.666. Layout for this view (it will match the default AE 3D setup). When ready to export… bake animations. Then group elements and transform group with above scale and translate settings.
Import into AE and delete the ‘group’ node which will be the parent to all the elements. Their transforms will now be set up to match AE world with center @ 960×540 (***This assumes you want to create a 1920 x 1080 comp. Don’t for get to set your resolution in Maya to match this resolution!)
If it is more convenient to do the transform in AE only…
- Import elements.
- Create a null. Set Position to 0,0,0
- Parent elements to null.
- Set null position to 960,540,0
- Then scale null to 10,000.
- Delete null.
Camera and elements will now be in AE default 3D space.
[UPDATE AGAIN -- possibly ignore all this... i think I found my mistake!]
Maya 35mm camera seems to be off when brought into AE… changing angle of view of AE Camera to 66degrees (or change to film size to 36mm) and that should help slippage off-center.
Another way to calculate what the AE Camera needs to match the Maya camera is to take the Maya Camera’s ‘Camera Aperture’ X value and convert that to mm (mult by 25.4 to get millimeters). Then use that value for AE Camera’s film size. I think the problem is that maya has a default ‘user’ film gate that is a 1.5:1 ratio, which is going to be different then your AE 1.78 comp ratio.
It’s called gigrunners.com and currently sports a nifty forum for discussions of all things gig-gy.
Just a note to say that a brand new restaurant app has been released into the wild. This one is for another local favorite: The Coffee Table.
Enhanced for the retina display, this is the latest and greatest version of the restaurant I have developed to date.
Check it out! The Coffee Table App in the AppStore.

Look out Eagle Rock…

For those who might be interested I am going to give a promo code good for a free download of “Meat Clock” (the original Meat Clock for iPhone and iPod Touch) to the first 5 people who use the contact form on this site to request it. Please, only one request per person!
This is a great opportunity to share the love if you already own Meat Clock and would like to “re-gift” it to someone special.
In the event that you request a free code and the 5 person limit has already been reached, I suggest you include in your message an interesting or juicy story that might get you some sympathy, and possibly a free code…
(boy, this iPhone development stuff is just like playing God!)
Not your typical iPhone developer
I just read an interesting story over at Macworld about iPhone developer ‘Molinker’ posting fraudulent 5-star reviews for its apps. I didn’t know that they have over 1,000 apps in the App Store. With their apps removed from the store, perhaps shopping for an app won’t feel so much like trying to navigate the shopping mall the weekend before Christmas! All for the best, I suppose. Maybe Meat Clock will finally catch on with the masses. Did you know that Meat Clock makes the perfect gift for your friends and family? Well, it does.

Brownstone Pizzeria iPhone App, Quick-dial screen
This just in… APPROVED: iPizza: Brownstone Pizzeria – Eagle Rock, CA. This one is targeted to the local small business. In this case, I’ve created an app for Brownstone Pizzeria in Eagle Rock, CA. This place has delicious thin-crust pizza and the owners are really great.
The Brownstone Pizzeria App was an excercise in creating an app that could be easily translated to work for other pizza places, restaurants, or any business that might want to give away a free app to their customers, offering them a chance to tap into any daily specials that will keep them coming back for more (and more often). And the easy quick-dial button makes phone in orders a breeze.
I could see making an app like this for anyone interested. In fact, if you are interested you can contact me here.
Now Available in the iTunes App Store Brownstone Pizzeria App.
