Built-in variables
You can use built-in variables in Substance function graphs order to access specific values. They always begin with a $
(Dollar) symbol.
Some variables are only available in specific contexts.
All nodes
|
Type |
Purpose |
---|---|---|
$size |
Float2 |
Returns the size of the current node in pixels. If used in the Output Size parameter set to a Relative to... inheritance method, returns the inherited value. |
$sizelog2 |
Float2 |
As above, but returns the size as power-of-2 values (ex: for 2048*2048 image, If used in the Output Size parameter set to a Relative to... inheritance method, returns the inherited value. |
$tiling |
Integer |
Returns an integer value corresponding to the current node tiling mode (inherited or absolute):
|
$physicalsize |
Float3 |
Returns the graph's Physical size property value. |
$uvtile |
Integer2 |
When using UDIM workflows, this variable returns the index of the current udim in U and V. E.g., (2, 0) for tile 1003, (7, 11) for tile 1118, ... |
FX-Map
Name |
Type |
Purpose |
---|---|---|
$pos |
Float2 |
Returns the birth position of the pattern. The origin (0, 0) is located at the top left corner of the image. |
$depth |
Float |
Returns the octave (level) number of the FX-Map node. This allows a node to modify its behavior according to which level in the quad-tree it represents. |
$depthpow2 |
Float |
As above, but returns the multiplicative inverse of 2 raised to the power of the octave (level) number – i.e. 1/(2^octave). This is a helper value that comes in useful for some common calculations. |
$number |
Float |
Returns the number of the drawn pattern. This can be accessed by Dynamic Function graphs controlling an Iterate node to modify its behavior at each iteration step. Note that When using a chain of Iterate nodes, the |
Pixel processor
Name |
Type |
Purpose |
---|---|---|
$pos |
Float2 |
Returns the position of the pixel being evaluated. |
Global
Name |
Type |
Purpose |
---|---|---|
$time |
Float |
This variable returns the time in seconds since the Substance Engine was started. It may be used in graphs which result should change according to elapsed time.
Note:
While there is currently no way to make this value change in Designer, applications that integrate the Substance Engine can leverage it, such as Substance Player for animation or Substance 3D Painter for dynamic strokes. |
$normalformat |
Integer |
The normal format (I.e., DirectX or OpenGL) that used in the current environment.
Note:
This variable has no effect in Designer and may be used by other applications that integrate the Substance Engine. |
