New in Tungsten
Composite is a new content type in HDR Light Studio.
Instead of a light getting its appearance from a loaded texture or procedural image data - the appearance of the light comes from a set of HDR Light Studio lights held within the composite.
See here for Working with Composites
New Arrow Buttons
Lights containing Composite content have an arrow button on the right side of the light list.
Press the arrow button on the right to Edit the Composite and display the composite's lights on the light list and canvas.
When editing a Composite. The Light List will display the name of the parent light at the top, and will list the lights in the composite below. It will also show a left arrow button at the top.
Use the left arrow button to return to the Light List containing the parent light - this is like moving up a level in the lighting design.
In short, these new arrow buttons on the light list allow users to navigate 'in' and 'out' of Composites.
A composite can contain another light which also has composite content. The arrows get very useful for navigating these multi-level lighting designs.
