CyclesShaderBall

Generates scenes suitable for rendering shader balls with Cycles.

user

Container for user-defined plugs. Nodes should never make their own plugs here, so users are free to do as they wish.

out

The output scene.

enabled

The on/off state of the node. When it is off, the node outputs an empty scene.

shader

The shader to be rendered.

resolution

The resolution of the shader ball image, which is always a square.

environment

An environment map used for lighting. Should be in latlong format.

device

Device(s) to use for rendering. To specify multiple devices, there’s a few examples under presets.

To render on CPU and the first CUDA device:

    CPU CUDA:00

To render on the first and second OpenCL device:

    OPENCL:00 OPENCL:01

To render on every OptiX device found:

    OPTIX:*

To render on everything found (not recommended, 1 device may have multiple backends!)

    CPU CUDA:* OPTIX:* OPENCL:*

threads

The number of threads used by Cycles to render the shader ball. A value of 0 uses all cores, and negative values reserve cores for other uses - to be used by the rest of the UI for instance.

shadingSystem

Shading system.

OSL : Use Open Shading Language (CPU rendering only).
SVM : Use Shader Virtual Machine.
