Hello,

Can ground plane feature be implemented in ospray ? It is very useful for environment light,

The example of it in THREE.JS https://threejs.org/examples/?q=ground#webgl_materials_envmaps_groundprojected

On the pathtracer you can set vec4f parameter shadowCatcherPlane, which describe the coefficients of a plane equation (i.e., normal plus distance). Note that this is an experimental, undocumented feature...
