Diving Straight into Photographic Rendering - Photographic Rendering with V-Ray for SketchUp - page 24

Looking in the Materials List section, you can see that we have a material named
Basic . This is the plain grey material currently assigned to all the geometry in the
scene. As we want to alter this arrangement, we need to briefly cover the setup or
current state of geometry in the scene.
What I am referring to is the fact that everything in our scene at this moment in time
has been turned into either a group or a nested group. This, for those who may
be unfamiliar with SketchUp, will affect how we go about applying materials to the
geometry. For instance, with one of the shelf objects selected, I can right-click on
Shelves material in the Materials List section and choose the Apply Material to
Selection option.
The selected material is then applied to that geometry. However, if I select a geo-
metry group such as the main building itself, those same steps will no longer work
and the material application would fail.
To apply a material to this type of geometry, we need to perform the following steps:
1. Double-click on the main building geometry to open up the group.
2. In the Edit menu, use the Select All command.
3. Right-click on a material in Materials List , such as Building Paint , and then
choose the Apply Material to Selection option.
Note
Once a group is open, we close it by using the Close Group/Component
command from the Edit menu.
We need to follow a similar process when working with nested groups. Applying a
material directly to a nested group such as our table won't work. However, we can
perform the following steps to attain the desired result:
1. Double-click to open the nested hierarchy.
2. Left-click to select one of the groups.
3. Select a material from the Materials List section.
4. Right-click and choose Apply Material to Selection .
