You can create a simple cube just from 3D layers in a pre-comp, then use that pre-comp with collapse transformations to animate the cube. You might also find this of use:
If you have a lot of different combinations, indeed using pre-rendered clips for each number would be the most efficient way.
Making your dice roll along the floor may prove to be a challenge. Take a look at this old tutorial I made (CS3) a while ago called Square Wheels. It wouldn't take much to modify the technique to roll a cube. AE Tips and Tricks: Square Wheels
I took a few minutes and updated the comp to a rolling cube by adding a couple of nulls. Here's a CS6 version of the project: rollingDice.aep
Thanks Rick and Mylenium!
I'm at work right now so I will take a look at the links and such later tonight.
Thanks for the tips.
While the rolling dice comp that you attached looks great...it isn't what I was really envisioning. If you don't mind...can you take a peek at this youtube video? Battle Report (Complete) - Ogre Kingdoms vs Warrior of Chaos (2500pts) - Warhammer Fantasy - YouTube
If you fastforward to the 20:43 mark you will see something that I am trying to replicate. Along the bottom you will see little dice that spin in place for a second and then stop on whatever result the player is rolling on the table.
Do you guys have any suggestions or tutorials that explain something like this?
