Image Shading
Updated: 4 Dec 2023
Shades particles based on an image.
Image Shading
Method #
This node shades particles based on pixels sampled from an image or input video source.
For this node to operate an image must be supplied either via the Image attribute or connected via the Image Node input. When an Image Plane node is connected to the Image Node input the transform from the image plane will be used, so the sampled pixels correspond with the pixels on the image plane in 3D space.
Parameters
These properties control the core behaviours of the node.
Parameter Details Image Override the input image with an image selected from the drop down menu.
Warp X Mode Changes what happens at the edge of the particle image along the x axis.
- Clamp : The colours of the image on the left and right of the image are stretched to fill space.
- Repeat : The whole image is repeated to the left and right of the image to fill space.
- Mirror : The image is mirrored repeatedly until the space is filled.
- Border : The image is clipped and filled with black.
- Clip : The image is clipped, and filled with white.
Warp Y Mode Changes what happens at the edge of the particle image along the y axis.
- Clamp : The colours of the image above and below the image are stretched to fill empty space.
- Repeat : The whole image is repeated above and below the image to fill empty space.
- Mirror : The image is mirrored repeatedly until the space is filled.
- Border : The image is clipped and empty space is filled with black.
- Clip : The image is clipped, and empty space is filled with white.
Blend Mode Choose how the particle colours blend to the source colours
Blend Amount Control how much the new shading affects the particles.

| Name | Description | Typical Input |
|---|---|---|
| Image Node | The image source node. If an Image Plane is used, its transformation values are used too. | Video Node |
| Affected Emitters | Choose which particle emitters can be affected by the affector. | Primitive Emitter |
| Transform Modifiers | Apply the transforms of another node to this node. | Null |
| Target Node | Modifiy the rotations of the node to always direct the z axis towards the input. | Null |
| Local Transform Override | Apply the transforms of another node to this node, relative to its parent. | Null |
