Sample Reflected Cubemap Node
Description
Samples a Cubemap with reflected vector and returns a Vector 4 color value for use in the shader. Requires View Direction (View Dir) and Normal inputs to sample the Cubemap. You can achieve a blurring effect by using the LOD input to sample at a different Level of Detail. You can also use the Sampler input to define a custom Sampler State.
If you experience texture sampling errors while using this node in a graph which includes Custom Function Nodes or Sub Graphs, you can resolve them by upgrading to version 10.3 or later.
Ports
| Name | Direction | Type | Binding | Description |
|---|---|---|---|---|
| Cube | Input | Cubemap | None | Cubemap to sample |
| View Dir | Input | Vector 3 | View Direction (object space) | Mesh's view direction |
| Normal | Input | Vector 3 | Normal (object space) | Mesh's normal vector |
| Sampler | Input | Sampler State | Default sampler state | Sampler for the Cubemap |
| LOD | Input | Float | None | Level of detail for sampling |
| Out | Output | Vector 4 | None | Output value |
Generated Code Example
The following example code represents one possible outcome of this node.
float4 _SampleCubemap_Out = SAMPLE_TEXTURECUBE_LOD(Cubemap, Sampler, reflect(-ViewDir, Normal), LOD);
