3D node
HDRI
Loads an equirectangular HDR/EXR image and hands it to Render 3D as a real image-based environment, replacing the built-in sky gradient. Exposes intensity and a rotation so you can dial in brightness and spin where reflections and light come from.
What it does
HDRI is a 3D node: it builds, changes or lights geometry that Render 3D turns into a picture. It has no input and gives environment out, so it starts a chain.
Try it
Load an HDRI of a sunset and slowly animate its rotation to sweep studio-quality reflections across a metallic object.
Inputs and outputs
Inputs
- None. It starts a chain.
Outputs
- environment out
Controls
Every control with a range can be driven by a modulator, a note, an audio level or a sketch.
| Control | Range or options | Default |
|---|---|---|
| intensity | 0 to 8 | 1 |
| rotation | -180 to 180 | 0 |
Example patch
