Hi. Im not really sure what i understand you problem correctly, but it looks like you just need to rotate you forward vector with object.*
*upd: or more correctly to say: rotate forward vector with some vector from object themselve, which will keep traces in correct directions.
Here’s an example. In those case traces will always “properly” oriented to objects. I.e. traces will be rotated with you object in every directions and so on. No matter how you rotate you objects, traces will in same place respectively with same rotations.
Pastebin code.
Hope that helps
