Exposed Parameters & Globals

An exposed parameter is a node parameter promoted to project level, so it can be driven from one place without hunting down the node that owns it.

The expose toggle

Next to every parameter name in the Properties panel is a small diamond:

Hollow ◇: not exposed. Click to expose.
Filled ◆: exposed. Click to unexpose.

The Global Variables panel

Exposed parameters appear in the Global Variables panel (Globals tab) with exactly the same live controls, so key values from anywhere in the graph can be edited from one place. Each entry carries a ✕ that removes it from the panel. The diamond does not appear inside the Global Variables panel itself.

The panel always shows the exposures of the graph you are editing. Enter a subgraph and it swaps to that subgraph’s own exposures; come back out and the material’s set returns.

Exposures are saved into the project archive, so they travel with the project. Exposures whose node has since been deleted are pruned automatically, so the panel never shows dead entries.

Collapsing exposed nodes into a subgraph does not lose their exposures: they become parameters of the subgraph node itself, held per instance. See Subgraphs.
