3D Impressions Help - Reflections |
|
With scene reflections you can specify the scene's virtual surrounds that can then be seen reflected in chosen object material surfaces.
These surroundings can be considered as being a 6-sided virtual room that your scene is created within.
Setting Scene's Reflections
This is where you define the scene's virtual surroundings.
To access them, use the 'Reflections' button on the 'Home' ribbon category, as shown below.
These settings are presented in the 2 parts of:
- The image to be reflected.
- Advanced settings affecting how this image is created and used.
Reflection Image
Here the following options are available:
Advanced Settings
The following advanced settings are available:
- Reflection Size
This selects how detailed and how much graphics memory is used to create the virtual room.
The lower the quality setting, the more blurred the reflections can appear.
There are 2 types of settings:
- Auto - Chooses a size based on the dimensions of the chosen image and the Low, Medium or High quality.
- Width x Height - Selects the number of pixels wide and high each of the room's 6 sides contain.
- Reflection Distance
This defines the size of the virtual room.
The bigger the room, the further away the wall behind the viewer appears within reflections.
- Picture Mapping
When using a Picture File, this defines how the image is applied to each of the room's sides.
In addition to images suitable for reflections included with the product, more are available to download in the
CyberFlair 3D Impressions Online Galleries.
Picture on 6 sides |
 |
The picture shown to the right is copied to the 4 walls, floor and ceiling of the virtual room. |
 |
Picture on 4 walls, roof & floor approximated |
 |
The picture shown to the right is copied to the 4 walls.
The floor and ceiling are estimated from the top and bottom of the image file. |
 |
Picture on wall behind viewer |
 |
The picture shown to the right is copied to the wall situated behind the viewer. |
 |
Wrap to 4 walls, roof & floor approximated |
 |
The picture shown to the right is wrapped to the 4 walls.
The floor and ceiling are estimated from the top and bottom of the image file. |
 |
Cylindrical Wall Wrap, roof & floor approximated |
 |
The picture shown to the right is cylindrically wrapped to the 4 walls, which makes the room look less square.
Because the left & right edges of the image used don't join, the seam can be seen in the center of the reflection.
The floor and ceiling are estimated from the top and bottom of the image file. |
 |
Cylindrical Wall Wrap, roof & floor approximated (far stitch) |
 |
The picture shown to the right is cylindrically wrapped to the 4 walls, which makes the room look less square.
To better hide the fact that the left & right edges of the image used don't join, the room is turned around so that the seam would appear on the far side of the object.
The floor and ceiling are estimated from the top and bottom of the image file. |
 |
Spherical Wrap |
 |
The picture shown to the right is spherically wrapped.
Because the left & right edges of the image used don't join, the seam can be seen in the center of the reflection.
This mapping it particular suited to images specifically created as a spherical panoramic.

Setting Material Reflectivity of an Object
To specify how reflective a particular material is, use the 'Reflectivity' property available on the 'Material' context ribbon category, as shown in the diagram below.
This setting is also available with the Material Properties tool window.
The material's reflectivity value is expressed as a percentage of how reflective it is.
A value of zero means that the material is non-reflective.
A value of 100% means that the material is like a pure mirror, which results in none of the material's other appearance properties having an effect.
So even if the object was colored red, this will not be discernible.
