[Unity3D 3.5.6f4] Blob shadow projector artefact

Hello Unity’s community.

I know about unity for a few years, but i just started working with it few days ago. But like many users i came across one of the main trouble you get with the free version of unity… the dynamic shadows, or the lack of it. So i’m trying to mess with projectors to get something that looks like a shadow. But i’ve got another problem.

Here is a quick scene i made so you can see the artifact i got using projectors.
Shadow Projector test scene
Controls → ZQSD or Arrows to move the vehicle, F for Open/Close the door and R to restart the scene.
Sorry i didn’t tweak the physics.

There are 5 projectors that follows the “car”, one for each wheels and one for the structure. But there are dark stripes laying on the ground form the wheels, you notice it when you move the car. How can i get rid of it?

i have never come across this problem before, but by investigating the problem, it might have something to do with the camera. try tweaking some settings there. Sorry i could not be much help, But i have never seen this before!

So you see it in the preview, right?
