Often you will need to change how rapidly a texture or material is repeated over a surface. This is referred to as texture scaling, or sometimes as UV-scaling.
Suppose you have a material where the texture is too 'stretched-out'.
We can fix this by changing the texture scaling.
In SketchUp, show the material dialog with Window -> Materials.
Select the material you wish to scale with the picker tool. In our case we will select the wood material on the ground object.
Click on the 'Edit' tab.
In the 'Texture' section, change the horizontal width to a smaller value, such as 0.3 m.
The texture should now repeat more rapidly over the surface, in SketchUp and in Indigo as well, when the scene is exported again.
The same technique can be used for procedural materials, which may not use a texture map. In this case, you can use a 'dummy' texture, by clicking 'Use texture image' in the Materials edit tab, and then selecting a dummy texture. The dummy texture will be displayed in the SketchUp viewport, but will not affect the Indigo render.
