Thanks for getting back to me.
i will try what you have suggested. I am not very well versed in expressions and usually just try to modify ones i have already used .
I used .04 for the time remap beacuse when i used 1 it remapped 1 second and .04 remapped one frame.
What does the command ‘index’ mean ?
reading what you have written does it say to take the information from the top layer everytime ? Unless that is what index is doing ?
anyway , cant pretend to understand it
but i will try it
again
Thanks
