Hi all,
Below is the link you can download a little project of mine.

In this project, I form the car with particles. As the car is coming towards the camera it keeps generating more and more particles. I want the car and the contrails to be blended with each other. Sandy kind of dust is my aim for rendering.

feel free to comment.
