Before you do anything in Reaction, be sure to verify that your Player settings are set properly.

To set the Player display settings for Reaction:

1. With the cursor over the Player, press the tilde key (~) or middle-click to display the Gate UI. Swipe south to display the Player Options.

   

2. Under Display, select Tool Output to view the results of your Reaction composition in the Player.
   NoteWhen you are working with a default Compositing task group preset, Tool Output is enabled.
   TipYou can set a context point for the Player to display the Reaction output. This is useful when you are working with more than one player, or you are editing a composition with Reaction using the Layer Editor and you always want to see your Reaction output—see Setting Context Points.
3. Under Guides, select Manipulators to view transformation and object icons. Manipulators is enabled by default.
4. Under Reaction, select a plane (XY, XZ, or YZ) for the grid, adjust the size of the grid and the distance between grid lines. The grid helps you place elements in 3D space.
   NoteTo work with grids, you must select the Interactivity option (under Reaction).
5. Under Reaction, select a Highlight option for displaying objects:
   • Coverage: Display the pixels of selected layers that contribute to the final composition. Adjust the transparency of the pixels by entering a value in the Threshold field.
   • Object: Displays an object's geometry with a colored outline.
6. Under Reaction, select Interactivity to use the hardware renderer and achieve dynamic results while you work. The results you see when working with the hardware renderer may differ slightly from the results achieved using the software renderer.
   NoteIf you are planning to quickly composite a series of 2D layers without manipulating or transforming layers or adding 3D effects, you do not need to enable Interactivity.
   NoteTo work with lights and cameras, you must also select Icons (under Rendering) in the Render tab of the Reaction tool.
