Hi Matt >whats wrong with the: .../Realsoftxx/tutorprojects/material/vsl/matteshadows.r3d
For many reasons I need two planes ... a vertical "wall" - doesnt matter if it's cam background or not .... and a plane for the surface the object sits on (usually horizontal) and might be a bumpy SDS surface for that matter. A single surface plane only works if the surface is an infinite rectangle and the cam POV is aimed below the horizon for that rectangle. And on a quick test, I cant get that material to do both. But, looking at the material VSL code, I cant see why I cant get it to work. Maybe somewhere between the color mapping material and the matte shadow light handling is where I should be looking. Have to run now.

A very simple shader, which should give a good result :-?

And while it's a solution, I cant recommend it. Lol. In any case, uses light sensitivity controller material rather than self illumination (on left).

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.

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.

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.
