Depending on whether you are using the hardware or software renderer, you can set some rendering options and effects. When you use the software renderer, you can set the Depth of Field and Motion Blur effects, and specify the number of samples to take, and select a filter for anti-aliasing.

To set Rendering and Effects Options:

1. With the cursor over the Player, press the tilde key (~) or middle-click to display the Gate UI. Swipe through Player Options.
2. Under Reaction, select Interactivity to use the hardware renderer to preview results in Reaction. Deselect Interactivity if you want to use the software renderer.
   NoteThe hardware preview in Reaction does not affect the Reaction output to any tools downstream, and does not affect the published results.
3. In the Reaction UI, select the Render tab.
4. Under Rendering, set rendering options.

   Parameter	Description
   Filter	Applies filter effects on your composition. Choices are listed in order of speed and quality: Box, Conic, Max, Quadratic, Narrow Gaussian, Medium Gaussian, Wide Gaussian, Cubic, Cook, and Mit-Net Noch. The Box filter is ultra-fast, but low quality. The Gaussian filters give more blur. The choice you make also depends on the number of samples used.
   Samples	Sets the number of samples. A larger sample gives higher quality but slower speed. This is used with the software renderer only.
   Shading	Turns on/off shading. You may want to disable shading for generating a draft result.
   Shadows	Turns on/off shadows.
   Image Filtering	Applies image filtering.
   Wireframe	Enables surfaces to render in wireframe.
   Icons	Displays light, camera, and axis icons. You must also enable Interactivity in the Player options to view the icons.

5. Under Fx, set the effects options.
   NoteYou must have software rendering enabled. To enable software rendering, deselect Interactivity in the Player options.

   Parameter	Description
   Anti-aliasing	Smooths the edges of rounded surfaces and diagonal lines.
   Depth of Field	Includes DOF in your scene. This effect simulates a plane of maximum sharpness and blurs objects close to or beyond this plane.
   Motion Blur	Adds motion blur to your scene.
   Z-Buffer	Uses the Z-buffer in your composite. The Z-buffer works with hardware and software rendering.
