Local Environments
Patchwork 3D supports local environments so that materials used by certain geometries can reflect their immediate, or local, surroundings.
The button Create a local environment 
allows an environment of the Local Environment type to the list of available environments.
To assign this local environment to a group of surfaces, just hold the Shift key down and drag-and-drop the local environment onto the desired surfaces (see section Multiple Environments).
Note
By default, the local environment initializes at scene coordinate 0,0,0 and captures its immediate environment.
Depending on the scene, a plane or a surface can hide the environment nearest to the initial point of capture, in which case the local environment will appear dark and very few elements will be discernible.
Setting Local Environment Parameters
To show the environment around a gear lever knob in the reflection of chromed material, parameters have to be set for the local environment.
To do this, open the Environment Properties by double-clicking on the Active Environment thumbnail.
Select the Pick the capture origin tool
then click on a point on the gear knob to position the origin of the capture point.The Display and move the capture box tool
allows the capture box to be displayed and moved, showing the zones from which the local environment images are going to be captured.
It is possible to adjust the size of the capture box by changing the value of the Radius parameter.
Tip
Capture of the environment must be consistent with the object to which the local environment is assigned.
It is therefore necessary to exclude from the capture the surfaces relating to the object:
either by using the tool for exclusion of surfaces and entering the name of the surface.
or by ensuring that the box is larger than object in question.
The Refresh environment button
allows the environment to be updated by recalculating the images captured by the local environment box.The environment thumbnail then displays the captured environment.
The chromed material applied to the gear lever knob reflects this new environment.
The reflection of the environment on the material can be adjusted with precision by manipulating the value of the adjustment parameters in the General properties zone.
