I have two choices for them when I go backward : - I freeze them all, but with somketrails it becomes messy. - I destroy them all, and start again to emit them only when I go forward.
Having a good behaviour for the particles going backward should be great, but by looking into the code it doesn't seem to be easy. :/ -- Serge Lages http://www.magrathea-engine.org
