(Reflectance shader)
This shader will create a layer of “dust” or a tarnish on an object. The effect is layered on the object from a particular direction in world space, from either an infinite or point source, and also varies with the angle of view (as dust is normally more “solid” and obvious at steep angles than when looking directly at the dusty surface).
Sample image showing TG Dusty used on ball, floor and table legs.
The sample image shows the shader being used on the ball, the floor, and the table legs, to simulate a thin layer of dust. Note how on the ball, the surfaces facing away from the viewer are more grey from the dust, while those facing the viewer are less grey and dusty, to simulate how the opacity of dust appears in real life.
Note that on the floor, the angle of view has an effect too, with the more distant surface appearing grey and flat, while the nearer part of the surface shows more of the wood colour, as well as appearing more reflective.
Finally, you can see on the table legs how the dust “collects” on those surfaces facing in a particular direction.
(Reflectance shader)
This shader lets you create blurred reflections, rather than pin sharp reflections. It allows you to balance the quality of the effect against the render time, so will let you come up with a mix suitable for the needs and priorities of each render.

The shader works by calculating multiple reflections,
each offset from the other. You can individually activate or deactivate
offsets to the left, right, up and down of the “ordinary” reflection, and
control how many steps the offset is divided into, how each offset reflection
fades in intensity compared to the previous, etc.
The shader is designed to be used as a layered shader, so calculates nothing but reflection, and is ideal for creating softer, less harsh reflections (sometimes even a low quality setting, which will render quickly, can be enough just to soften up a reflection). Note that the sample image on the left has TG Blur Reflect on the floor material also, allowing the yellow and green colors to show through without looking too much like an actual reflection in this image. The main sculpture object itself also uses TG Blur Reflect, of course.

(Reflectance shader)
This shader is designed to create glitter or metallic paint or flake type effects. As well as some processing which will be familiar to users of the TG Noise shaders, it also comes with some unique processing designed to enhance the glitter and metal flake type look.

(Colour shader)
This shader is designed to painted onto a “sky sphere” object, only the object can be as simple as a cube, as the number of sides no longer matters. Instead of rendering on the surface of the object, the shader projects onto an infinite plane, and renders based on that instead.

On the left, the scene set up, showing the cube (in white) surrounding the scene and painted with TG Infinite Plane Cloud, while the right shows the rendered output.
However, as well as rendering on an infinite plane, the shader also takes an unusual approach to generating the clouds. It creates its own simulation of displacement from the noise parameters ser by the user, and then uses its own lighting routines for Ambient (non directional) light, Sunlight (directional), and Ground light (always straight up).
Although only capable of simulating the “bottom” of a cloud rather than a full 3D cloud, it still gives an unusual and unique effect, which is capable of producing some nice clouds and skies.

(Displacement shader)
This shader creates grooves on the surface of an object. All very ordinary, except it lets you set a very high number of grooves, with a range of groove types to choose from, plus extra noise which can be added in also. The end result is a shader which is capable of giving a range of “roughening” effects to a surface, including generating blurred reflections and refractions.
Several samples using TG Groovey Displace. to illustrate the range
of effects possible with the shader.
