Inconsistent particles.

The full anme file and a movie is now posted here.

There appears to be no problem at the beginning of the project. The point when it becomes possible to view the problem is around 600 frames, as the mice are leaving.

It is during faster action that the effect is most prominent but the gaps appear much less than every 24 frames.

Yes the last bit at the end. It is most noticeable with the last two mice furthest away. They have to travel much faster in a longer distance in a shorter time frame to go off screen.

The gaps appear shorter than 24 frames but they are emitted in "clumps" based on the velocity. I think that the mouse moves faster than the velocity. You need to find the balance between distance moved and the velocity of the particle layer.

You probably need to have an "alternate" particle layer just for those two mice. The others look fine to me. I did a test that worked pretty well. Rather than posting it I will just tell you the numbers I used that seemed to help a bit. I only fiddled with the LAST mouse. The one furthest away and ONLY for that last part when he zips off screen.

I tripled the particle velocity from 3 to 9. I also tripled the "velocity spread" from 2 to 6. What this did was to "spread out" the particles more over the longer and faster distance that the mouse travels. You could play with those numbers for the next closest mouse if you think you need to.

Since you can't key frame the velocity this will require a second particle layer. A duplicate with different velocity and velocity spread that is only turned on for that last bit. Just that last spot where they leave the screen.

Another thing I just noticed.

The last mouse does not move "up" in the direction of his "angle". So this kind of makes the particle gaps more noticeable. Small thing.

I found even better numbers:

Velocity: 9
Velocity spread: 8

By the way.. this animation is absolutely wonderful!!!! I just LOVE it.

Thanks for the 'small thing' and the numbers. I'll give them a try.

Also thanks for the compliment. Working in a circle of one it means SO much to hear such things.

I've tried the suggested particle settings, and adjusted the angle of exit, and it is looking much better, thanks Vern!

Woohoooo! Glad to help out!
