The following example provides one way to use Brazil r/s 2.0 for Rhino and while there are many possibilities when it comes to rendering in Brazil, this method is a simple one in which photo realism can be achieved with minimal effort. Here's the Rhino scene we'll be working with...
You'll need the following files to render this scene yourself...
Download the zip file first and store the "Brazil rendering sample" folder somewhere memorable on your computer, be sure to leave all the files in the same location. The following instructions show how textures, materials and the environment were created for this model... Enjoy!
Make sure the textures have the correct address in relation to where they are stored on your computer... this is an important step. These textures will be added to materials and assigned to the objects in our scene.
HDR images or High Dynamic Range images can be used as both an environment for reflections as well as lighting. This HDR image is a blurred variation of one provided by Paul Debevec .
Selecting the "Material Editor" tab, we can assign the appropriate textures to each of our materials. Right clicking a material tab will allow you to make new textures or change the material type. Regardless of the material type chosen, the basic principle of assigning texture maps to customize materials applies.
There are only a few settings that you'll need to make sure are on in the "Brazil Options" panel and they're shown above. The level of quality for the rendering is controlled in the "Image Sampling" section "P3" being the highest default setting... higher quality = longer waiting time. So if you're playing around with textures keep it on P1 or P2 while you do your test renders. The "Luma Server" section is where you turn on "Global Illumination" for the default "Sky Light" in our scene... this is what makes for soft realistic shadows. That's pretty much it... this is a super simple but relatively fast setup. The size of the rendering produced is set to be the same size as the active viewport but you can change this in the "Output Size" section of the Options panel if you like.
