Sample Cubemap Node
Description
Samples a Cubemap and returns a Vector 4 color value for use in the shader. Requires View Direction and Normal inputs to sample the Cubemap. You can achieve a blurring effect by sampling at a different Level of Detail using the LOD input. You can also define a custom Sampler State using the Sampler input.
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 | Vector 1 | 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);
