Cast a shadow and light question
I have a problem with my scene. I have made car in maya. But now i have found a great background of a road with some buildings on it.
I have put the car on the road of the background by using the background as a image plane. But you can not see the shadow of the car on the road because it is an image plane.
So i put a plane under the car exacly as the road is in the picture. So the shadow will fall on to the plane. But i want the shadow to be visable but not the plane. So it looks like the shadow is on the road of the image plane.
I have started to play with the attributes in the render stat of the plane like, primary visabylity, receive shadow and so on.. But i can't get only the shadow.
I hope someone can help me with this.
The image plane i used for the car is one where it is sun rise. What i want is a like specular glow going from the back of the car to the roof of the car. Because the sun is comming from the back. And i am looking at the car form the side.
With what kind of a light, tool or trick can i get this effect?
Don't be afraid of what you can see, but be afraid of what you cant see.
