Shadow problem


Bobby

Recommended Posts

I used Rotoscope and Front Projection, placed Transparency Map in front of Key Light for shadow on the model.

Used Light List to get shadow on the model but not on the Ground.

This is my Animated gif.

I guess what you want is to not have a shadow in a shadow, right?

 

My first idea would be to paint out the shadow on the front projection image (or get a shot of the road where there isn't a shadow) and use your A:M lighting to recreate it so the characters shadow and the shadow on the road are the same shadow.

 

Another possibility, that requires some compositing program, is to use a "darken" composite mode to combine the shadow layer and the road. Instead of adding the darkness of the shadow to the road it only darkens the road where it was lighter than the shadow. The shadow parts of the road don't get any darker.

 

These are both tricky to do, but does that make sense?

Thank you very much robcat2075.

my target

1. I want to fake the shadow on the road hit the model.

2. I want 2 cuts for this scene with this rotoscope, first a long shot and second a medium shot.

I placed 2 cameras at same position but difference focal length, 29 and 145. (x5)

When use the focal length 145, I scale rotoscope = 500%

Every thing that what I want is very easy in A:M except the shadow on Front Projection.

A:M can add new Property. Can I add new Property "Darken Mode" to the Ground?

You fooled me... I thought those shadows were real!

 

 

I'm not sure I understand your setup exactly but how about this...

 

Instead of putting the tree image on the light, put it on a card in front of the lights (a transparency map) and arrange it so its shadow falls on the road and on the character:

 

Shadows.mov

 

When the same light is shadowing the character and the "trees" you'll get one proper shadow on the ground for both of them.

 

 

Here's the PRJ of my simple example case:

Yes I still have a light list for fill-in only the character.

from your suggestion I do many things.

This is original image used as rotoscope

shadow only from the image.

I try many ways with many tools to fit the shadow back to image in Choreography, but I can't do that.

"who needs a real shadow" Then I use new shadow image.

It's very good, but I did something errors like this.
