contactShadows

Runtime control of the scene contact shadows — .set / .get / .clear / .active, with .lights reading back the lights this frame's traces aim at and .refresh re-reading the scene's lighting. set takes any subset; omitted fields keep their value, and a strength of 0 releases the render pass.

For contact shadows a scene should simply have, author the ContactShadows component instead. The full description of the knobs and the pass is in the package readme: guides { path = "systems/contactShadows" }.
