IRender Tutorial - Reflection and Glow
SketchUp model rendered with mirror specular reflection. The image on the right has the mirror set to 90%, the floor set to 60% and the back wall set to 40%.
This Reflection and Glow
Tutorial
explains how to add reflective surfaces to your
SketchUp
model for use with
IRender
.
Mirror
reflection and
Specular Reflection
add
Photorealism
to your renderings. You can define materials as reflective in SketchUp and then they will generate reflections when you render them.
Glow
can create realistic lighting effects without having to add too many lights.
Guidelines
- Use a white color material 95% reflection for mirrors (so they will be more realistic and not reflect 100% of the light).
- For materials such as wood, try 60%, and then adjust it up or down to get the effect you want.
- For shinier materials, such as a tile or a shiny floor, try 85%.
Setting Reflection for Existing Materials

- Glow can add realism to your rendered image by providing lighting effects without adding additional lights.
- Glow operates by making an item display as if it were illuminated without using lights to perform the illumination.
- Typical uses for glow are:
- Neon Signs
- Lamp Shades
- Exterior windows which would be illuminated by interior lighting
Glow is set in the same way as reflection.
- By adding "_glowxx" to the end of a material name., or
- By defining existing faces or materials to have a glow.
