Hi Spliners :

ill tell about MUFOOF
Exist countless uses for the passes, one of them, is the capacity to work with Multiple Frames in Only One Frame ( MUFOOF ). Here i will show you, how to set parameters..
I use it to simulate a fast movement, GI, fire ..........
The general concept is to produce an action (it doesn't import how many frames it has) that will be executed in one frame ....
The secret for that is to alter the properties of the action inside CHO.

First Project -> Creating a spinning prop

 

-> model a simple helix and setup bones ( or download it here )

 

-> Create a new action , select the bone and select :
frame -------- set Z rotate to
25_______________90
50_______________180
75______________-90
100______________0

->of this you sort things out created a turn of 360 degrees in 100 frames

-> import model and action to a new Cho
in the action properties under CHO reset :
lenght = 1
repeat = 100 ( number of action frames )

and in rendering options set :
Passes = 100 (10x10)
motion blur to 100%

now render the scene and VOILA, you have all your action in one frame

 

Changing RPM

the MUFOOF base itself in the model“s position, then if you change it the MUFOOF will follow it... what I did was create a secondary action and I added it to model setting Blend Method to ADD in this action i didnt change any others parameters

SECONDARY ACTION :

select prop bone and set new Z rotation positions :
frame-----Z
15 _____ 90
30 _____ 180
45 _____ -90
60 _____ 0
75 _____ 90
90 _____ 180
105____ -90
120 ____ 0

I had to set 2 turns to complete the curve correctly

select all frames and shrink them

select frames copy , select the frame that you want to paste it .... paste ....
the amount of copy depends on the duration of the animation

lets change rpm in frame 120 .. select all frames before frame 120

shrink them
