Adding Receivers/Transmitters to the Photon Director.

Note: If you have a hierarchy of objects that will all use the same Global Illumination values, (like the chair and the columns) you can save time by highlighting the parent object and clicking the Propagate Values check box. This will copy the values you set for the parent object through the hierarchy to the object's children.

Adding the rest of the objects to the Photon Director and give them the proper values.

Here is a chart of object names and their Global Illumination settings.

Note: Do not add the sky object as a prop. It is a constant material and will cause problems with Global Illumination.

If you add the sky by accident, here is what you will need to do:

1. Remove it with the Remove Props button.
2. Save your scene,
3. Quit Softimage.
4. Run Softimage again.
5. Load your scene back in.

Do all this before you continue working. The Photon Director sometimes "forgets" to ignore objects that were once props, but have been removed from the list.
I have found that sometimes this is the only way to get the Photon Director to "let go" of an object that has been removed from the prop list.

If you preview/render your scene now it should look something like this:



It is still too bright. We need to turn down the lights.
