Creating the wall paintings using

bitmaps

To get our paintings in place, we are going to have to do a little bit of work with
SketchUp's Texture Position tool as we are (quite deliberately I should add) going
to make use of bitmaps that don't accurately fit the aspect ratios of the geometry to
which we are applying them. To show how this will work, let's perform the following
steps:

1. In the editor Materials list, create a new Standard material and call it Paint-
ing_01 .
2. In the Diffuse rollout, click on the map button, add a TexBitmap node,
browse to your Exercise Files | Textures folder, and select the Paint-
ing_01.png file.
3. Click on Ok to exit the texture editor and then click to select the Picture
Frames Up Close scene tab (feel free to adjust the view to suit as you work
here).

Note

It is worth noting here that our bitmap textures are being gamma corrected
or linearized on import when we use the Gamma Corrected option in Co-
lor space with the Gamma value set to 1.0 as we see in the following
screenshot. This avoids the oft-bemoaned situation where bitmap textures
used in a render look overly desaturated or washed out.

4. Using SketchUp's Select tool, double-click and then single-click on the right-
most frame to select the single plane picture panel that is part of this group.
