Texture, Mix Mode, Mix Strength
For more details on these settings, look up ‘texture settings’ in the index.
Figure 6: Transparency may be controlled by a
transparency map or by the Transparency Color.
You can load a texture as a transparency map using the three dots button. The brighter a pixel in the
transparency map, the more transparent the corresponding region of the material. A transparency
texture is similar to a photographic slide: Red parts of the slide allow only red light to pass through;
white parts allow all light through. With black, no light can pass through the slide.
You can use a transparent material with a light source to create a light map or ‘gel’ (look up ‘gels’ in
the index). If a transparent texture is assigned to a light source, the light will be ltered according to
the texture’s coloration, just like a real gel.
Dispersion
Dispersion set to a low value (left) and high value (right).
You can blur the transparency using the Dispersion, Min Samples, Max Samples and Accuracy settings.
The Dispersion value denes the strength of blur for the transparency. 0% means no blur. Increase the
value to increase the strength of blur.
Accuracy
This parameter will only be available if Dispersion is set to a value higher than 0%.
Increasing the Accuracy value gives a more accurate blur, but a longer render time also.
