PARAMETERS |
||||||||
![]() |
||||||||
Min Colour Range : Colour values The colour represented by black in the Ramp image. |
||||||||
Max Colour Range : Colour values The colour represented by white in the Ramp image. |
||||||||
Range : Unchecked / Checked When unchecked, the shader works with the angle between the direction of view and the surface normal as in previous incarnations of the TG Glow shader. This actually uses the Cosine of the angle between the two vectors, so introduces a non-linear sweep to the values (so what you see in the Ramp isn’t exactly what you get in the render). When checked, the shader does the extra bit of processing (so may be a little slower) in order to work back to the linear sweep of the angle between the two vectors, so moves through the Ramp values in a linear fashion. |
||||||||
Range : Image Used to control the transition points between the colours dependent on angle of view. Black represents the “Min Colour”, white represents the “Max Colour”, the left edge of the Ramp is the outermost edge of a sphere (that is, surfaces pointing almost at right angles to the direction of view), while the right edge of the Ramp is the innermost surfaces on a sphere (that is, surfaces pointing straight back at the direction of view). |

Use True Angle : See previous |
||||||||
Angle Ramp : See previous |
||||||||
Angle Gradient Range : Image Used to control the colours dependent on the values in the Ramp image. The leftmost edge of the Gradient image is read for black in the Ramp image, and the rightmost edge of the Gradient image is read for white in the Ramp image. Greyscale values between white and black read from proportionally along the Gradient from left to right. |

||||||||
Minimum Opacity Range : -5 to 1 The opacity represented by black in the Ramp image. Negative values are permitted for unusual effects (see the Tips page, which duplicates the documentation from the free shader, TG GlowT). |
||||||||
Maximum Opacity Range : -5 to 1 The opacity represented by white in the Ramp image. Negative values are permitted for unusual effects (see the Tips page, which duplicates the documentation from the free shader, TG GlowT). |
||||||||
Coloured Transparency Range : Unchecked / Checked Adds in coloured transparency effects. These affect the colour of the shadows, as well as the colour of the transparent object. Enabling this generally gives a much brighter appearance to the object. |
||||||||
Transparent Colour Range : Colour Values The colour to use in the coloured transparency effects (only has an effect if Coloured Transparency is checked). |
||||||||
Use True Angle : See previous |
||||||||
Angle Ramp : See previous |
