Bout time for me to give back to the community, And I think i found something that may be helpful, or maybe it will just turn out to be common knowledge, or something that has a simpler remedy, than what I propose, so feel free to comment, no hurt feelings here.

For that most simplest of motion trails on like a swinging arm i.e.

Render your complete scene---(this will be the background layer or place mat for the following to renders (in photoshop etc.)

Render only the action figure and anything that will be crossing in front of your action trail--- (this will be the last layer that on top of the Background layer, and the layer in step three)

Render the trail.
-Hide everything but the action character
-open up time line
-move the time up to frame 3 or 5
-click add key frame
-move player slider back from 5 to 1
- move arm/ body towards the origin of the motion...

if you move the slider back and forth you can see the action, that finishes in your final pose

render settings: save image file as a .png ( this will have a transparent background-- IMPORTANT)

Click motion box
-motion samples 7
-motion amount -235

now render.

You final image will be like a hamburger, with the bottom bun being your background (1st render) then your meat , being your blur trail (last render- you may need to tweak a little). Then the top bun will be your second render.

... now I will quietly wait till someone tells me that i have found the most difficult possible way of doing something that is quite simple, lol

disclaimer, I have no schooling in this stuff.

    Thanks for the tips. Isn't there a motion option in rendering though? So can't you just render the figure using this option and not bother with a "motion" layer?

    That method is just as valid as any I have read to date. The extra advantage to doing layers in a 2D prg is the control you have over the depth of the blur by the opacity of that layer.

    Is that really a negative number for motion amount?
