Allura Material Wizard

The Allura Material Wizard comes up when you right click on a material in your SketchUp model and select Allura / Create or Re-edit) Material

Right click anf load the Allura Material Wizard

Preset Base Materials

The presets select a Base Material, and default settings for Reflection, Transparency and Index of Refraction.

Each Preset has special shader properties which make the material more realistic.

For instance, many materials exhibit a Grazing or Fresnel reflection at the edges. The Base Materials automatically add that to the rendering.

Materials for Allura GPU for SketchUp - Powered by NVIDIA Iray®

When you right click on a SketchUp Material to assign rendering properties, you should start with one of the Allura Material Presets.

Matte / Clear

Matte will clear all settings, so when changing from one material base to another, if you click Matte first, it will clear the settings - such as transparency, which are not normally reset when selecting a materiel like glass.

The Ceramic Shader provides some reflection for Ceramic materials


Glossy example 50 90.png

Glossy Materials create smooth reflections from light, but not sharp reflections from other objects.

Water example 133 0.png

In addition to distortion - much like Thick Glass - Water also has "color absorption" based on the amount of water the light of objects behind the glass pass through.

See: Allura Water Material



Wood Varnished

Wood example 10 97.png

Wood looks realistic when it reflects lights. You can lower the Sharpness to get a more realistic, blurry, reflection.

See: Allura Wood Material

Thin Glass

Thin glass example 152 0.png

This glass does not distort objects behind it, but is does create reflections.

You should use thin glass for SketchUp transparent objects which are drawn as a single face, without thickness.

See: Allura Glass Materials

Thick Glass

Thick glass example 153 0.png

Thick glass distorts objects seen through the glass, and reflects light based on the Index of Refraction.

See: Allura Glass Materials

Frosted Glass

Frosted glass example 152 80 0.png

Frosted glass adds additional diffusion.

The sample above also has a SketchUp "Safety Glass" pattern on it.

See: Allura Glass Materials

Main Tab

The color and any texture from your SketchUp material will be used, but you can add rendering effect easily by selecting one of the Presets. Each Preset will set a Base Material and other parameters which work well for the preset. You can then change the parameters as desired.

  • Reflection - is the amount of light reflected from other objects. 1.00 is like a mirror, 0.00 is Matte, and will not reflect any light.
  • Sharpness - determines whether the reflection is perfect - like a mirror - or blurry - like wood, or wet concrete.
  • Transparency - determines how much light passes through the material - 0.0 is solid, 1.0 is fully transparent.
  • Index of Refraction - creates distortion in transparent objections, or Fresnel reflection in reflective objects.

Glow Tab

Glow allows any geometry to have emissive properties and act as lights, which lets you create objects such as screens, LEDs, light bulbs and projections. Emissive materials can use textured emission through bitmaps or use standard light profiles.

  • Note: The Iray+ Interactive Renderer will not display glow illumination of the scene; the object itself will be shown illuminated, but will not cast light.
