Target

CMake target: rayrai_pbr_material_grid.

Run

Run the build-tree executable:

./build-examples/examples/rayrai_pbr_material_grid

On Windows, run rayrai_pbr_material_grid.exe instead. This example renders in process with rayrai and does not need rayrai_tcp_viewer.

Details

• Loads rayrai/pbr/MetalRoughSpheres/glTF/MetalRoughSpheres.gltf.
• Displays a grid of spheres spanning metallic and roughness values.
• Animates the mesh orientation so highlights and shadows can be checked over time.
