I have been using the sandcastle example and have a entity which moves along a path and draws the path with a new material as it goes.
What I would like to achieve is the same thing but with a short change in colour just behind the entity as it moves. Ideally, this short change in color would fade out.
I thought maybe to add 2 entities, one which has a leadTime of 0 and draws the path. The other with my model which has a leadTime of 0 and a trailTime of say 10. This procedures a different colour trail just behind the entity as it moves but does not achieve the fade effect.
I noticed a Fade material but not sure if this is correct and/or how to use it?
