Renderers

Question 1

Rendering modes

Answer 1

Opaque
Cutout
Transparent
Fade

Question 2

The FIRST Material Parameter in the standard shader is Rendering mode

Answer 2

This allows you to choose whether the object uses transparency, and if so, which type of blending mode to use

Question 3

Opaque blending mode

Answer 3

This is the default, and suitable for normal solid objects with no transparent areas.

Question 4

Cutout blending mode

Answer 4

Allows you to create a transparent effect that has hard edges between the opaque and transparent areas. In this mode, there are no semi transparent areas, the textures is either 100% opaque, or invisible. This is useful when using transparency to create the shape of materials such as leaves, or cloth with holes and tatters.

Question 5

Transparent blending mode

Answer 5

Suitable for rendering realistic transparent materials such as clear plastic or glass. In this mode, the material itself will take on transparency values, based on the textures alpha channel and the alpha channel and the alpha of the tint color, however reflections and lighting highlights will remain visible at full clarity as is the case with real transparent materials

Question 6

Fade blending mode

Answer 6

Allows the transparency values to entirely fade an object out, including any specular highlights or reflections it may have. This mode is useful if you want to animate an object fading in and out. It is not suitable for rendering realistic transparent materials such as clear plastic or glass because the reflections and highlights will also be faded out.
