Hi Neil,

 

I guess he means a shadow from an object on a background plate. So the car is 
3D, the road is a picture. But you should see a shadow of the object on the 
background picture.

What you need is a horizontal rectangle. Project the image on this rectangle 
from the camera viewpoint. The material should be self illuminating, so that 
regular lights have no influence on it.

Put the car on top of this plane, and it will drop a shadow on it. Of course 
you need another vertical rectangle with the same camera mapped picture to 
serve as a background.

I hope this answer is clear enough.

 

Arjo.

Onderwerp: Re: Matte shadows

 

I dont know what a matte shadow is. Matte, to me means "excluded by shape" ... 
some shape is not included in some part of the effect.

 

But all this is easy in RS. 

 

For soft edge shadows I use a rectangle as a special light ... I would use this 
to get a soft edge shadow under a car for example.

 

If any of the above is any use, let me know and I'll give more detail, but I 
dont think it's what you are after.

 

Sorry I cant help.

 

Neico

Just normal matte shadows for composition. I recall I saw one tut from 
internet
which had a car and pavement made with RS, but now I cannot find it 
anymore.
I tried tut from manual, but it gives incorrect shadows. Perhaps I 
should export
only shadows for composition. Only problem is that I don't know how to 
do that.
