CG/Live Animation Pront Projection Problem

[Laconic]

Hi,

 

I've gone through the "Combining CG Characters With Live Action Tutorial" here (http://www.hash.com/users/ed/tutorials/fpm/fpm.htm).

 

I have built my shadow-catching models to scale (using a ruler on the real scene) and placed them correctly in reference to the camera. I have all the correct image properties on the shadow-catching objects and have turned Front Projection ON, but when I render them, I can see them as DARK distortions to the scene. I want the shadow, but not the CG objects darkening the areas in which they appear.

 

I have tried bringing the "falloff" down as close to zero as possible, but the CG shadow-catching objects don't disappear into the scene.

 

Is there a way to make my shadow-catching objects catch the shadows but not darken the scene when they are "Front Projected?"

 

Any help would be appreciated.

A rendered image would help:)

I'm not sure I understand what you mean, but you could try to increase the Ambiance Intensity on the shadow-catching models until they match better?

Hi!

 

I couldn't get a render up but the ambience intensity is something that seems to be working.

 

Thank you!

A picture would help.

 

The camera needs to be set for accepting all the light. I can't remember the exact setting, I'm at work now, but the camera should take in all ambient light... or something like that. The rest of the light for the scene should be done as it was when the shot was taken.

 

Also, you want the fall out for the shadows.

 

If it is the fallout for the lights, try to match a white in the scene. This will give it a more realistic lighting look as to the color of the image.

 

When rendering, add a little motion blur. This will help blend the image. Not too much!

 

I'll try to look for the camera setting tonight.

 

I did this with a still shot and the "Fat Guy" Model here:

For your objects that you want to be front projected & "catch the shadows" - you could turn on flat shaded and turn off cast shadows. Both the ground plane & box in this chor are front projected objects
