Here's a 3dm file with Brazil presets plus several materials and environments. It's a basic product studio scene which will be most useful to Brazil beginners. Import your model into the scene to assign materials. The "Brazil bridge renderer" section of the settings panel has presets that you can choose between for speed and quailty. There are also short descriptions for each preset but if you want to look through all the settings, you can unlock a preset in the preset manager.
