The Trick to Applying Materials in Vray for SketchUp

 A free tutorial from the Black Spectacles course 3D Rendering with Vray 3.2 for SketchUp and Rhino 5.

In this Black Spectacles FREE tutorial, you will learn something that’s kind of unique in SketchUp in terms of how it handles materials within components. You will learn about materials hierarchy, and how to apply materials in order to achieve your desired rendering.

This tutorial is part of the Black Spectacles course on 3D Rendering with Vray 3.2 for SketchUp and Rhino 5 in which you will learn how to bring a 3D model into Vray for SketchUp 216 and Rhino 5, render it out, and touch it up in Photoshop to give your final image a professional finesse.

Materials in SketchUp Tutorial

Step 1: Make a cube and group it

To start, draw a rectangle. Use the “Push/Pull” tool to turn your rectangle into a 3D cube.

You probably understand components and groups in SketchUp at this point. For example, you can take your cube model and triple-click on it to select all the faces. Then right-click and select “Make Group” to make it a group. Or you could also right-click to make it a component.

Step 2: Apply a red color to the entire cube

Go to the colors and paint the whole cube red. Keep in mind you’re painting the whole group red. So when you apply the material, it applies it to the whole object. If you render this, you see you have a red cube.

Step 3: Override the materials

It’s important to understand how Vray handles materials hierarchy as well. To demonstrate this, double click into the group to override the materials. Make one side of the cube yellow and one side green.

Then render the object, and you can see the entire cube is no longer red. Keep in mind you applied the red to the entire group. So the material that you put on the face directly, overrides the material that’s on the group.

If you intend to have a group that is a window for example, and you paint it all wood, you can still go in there and have your glass be part of it and then override with a glass clear material and render it correctly.

It’s important to keep in mind because it will come into play depending on how you model.

So remember, the material that is applied directly to the face, always overrides any material that’s applied at the group or component level.
