Set Shader Attribute
Original rendering, and result rendering of a SetShaderAttribute layout node : the t-shirt texture index attribute has been forced to a single value (red and yellow t-shirts) for entities on the left.
The SetShaderAttribute node forces the value of some specified shader attributes, on the affected Entities. The result is only in rendering as the shader attributes are not handled by previsualization.
Add node
- Drag the SetShaderAttribute node icon
from the Nodes Library panel and drop it in the Layout Graph Edition panel - Hit the Tab key in the Layout Graph Edition panel and select the SetShaderAttribute option in the dropdown menu that appears
SetShaderAttribute node in the Layout Graph Edition panel
Node parameters
Parameters are accessible by double-clicking on the node in the Layout Graph Edition panel:
SetShaderAttribute node parameters
| Name | Name of the node |
| Active | Whether the node is active or not |
| shaderAttribute |
nameOfTheShaderAttrToOverride newValue[;nameOfTheShaderAttrToOverride2 newValue2][etc.]. It is also possible to randomize the value by using the following template nameOfTheShaderAttrToOverride newValueMin newValueMax; Each attribute not associated with a value will take its value from the sampled map according to the channel setting and the entity position on the texture map geometry. If the entity root cannot be located on the map, the attributes using the map are not set. Examples:
tshirtIdx 1 |
| RandomSeed | This node use a specific random seed which can be modifier to change the attribute random pick results, when using random min/max values |
| Channel | Which value to use for the shaderAttribute : RGB Vector, or red, green, blue or alpha channel single value. |
| Target | The map target in the scene, used to sample values (in the RGB range [0-1]) at entity root position. This parameter will be used to automatically refresh all the following parameters. |
| Map |
This parameters should not be edited directly by the user. It will be automatically updated when the target vector field changes. Contains the texture map. |
| Geo Vertices |
This parameters should not be edited directly by the user. It will be automatically updated when the target vector field changes. Contains the geometry vertices on which the texture map is applied. |
| Geo Normals |
This parameters should not be edited directly by the user. It will be automatically updated when the target vector field changes. Contains the geometry normals on which the texture map is applied. |
| Geo UVs |
This parameters should not be edited directly by the user. It will be automatically updated when the target vector field changes. Contains the geometry UVs on which the texture map is applied. |
| Geo Triangles |
This parameters should not be edited directly by the user. It will be automatically updated when the target vector field changes. Contains the geometry triangles on which the texture map is applied. |
