Procedures To apply volume shading to a camera: 1 On the main toolbar, click Render Setup. If the active renderer is not already the mental ray renderer, go to the Common panel, and on the Assign Renderer rollout, click the "..." button for the Production renderer. A Choose Renderer dialog is displayed. Highlight "mental ray Renderer" in the list, and then click OK. 2 Click the Renderer tab to go to the Renderer panel. On the Camera Effects rollout, find the Camera Shaders group, and click Volume. The Material/Map Browser on page 5290 is displayed. 3 Choose a volume shader from the list in the Browser, and then click OK. To apply volume shading to an object: 1 Choose Customize > Preferences. Go to the mental ray panel, and turn on Enable Mental Ray Extensions. 2 On the main toolbar, click Render Setup. If mental ray is not already the active renderer, go to the Common panel, and on the Assign Renderer rollout, click the "..." button for the Production renderer. The Choose Renderer dialog opens. Highlight "mental ray Renderer" in the list and then click OK. Leave the Render Setup dialog open, or minimize it. 3 Open the Material Editor. Use the mental ray Connection rollout on page 5385 to assign a volume shader to the Volume component. Another technique would be to use the mental ray material on page 5638, and assign a shader to the Volume component. 4 Also on the mental ray Connection rollout, click the lock button to unlock the Surface component. Click the shader button ("None") and use the Browser to assign the Transmat (physics) shader to the surface. (If you are using the mental ray material, you don't need to first unlock the Surface component.) mental ray Renderer | 6267
