Use actor label for light identification/selection in editor; fall back on component name (UUID) temporarily until this data is made available outside the editor as well Collect debug data in RayState for SMRT and return the last valid sample data - Alternative is to always generate debug data based on just a single VSM sample even when SMRT is enabled, but it's useful to have a debug output path for the true SMRT data, even if a bit more complex Move some common visualization utilities to /Visualization.ush Implement but disable backface culling for shadow evaluation pending change that handles various SHADINGMODEL's properly #rb graham.wihlidal, ola.olsson #ROBOMERGE-SOURCE: CL 16407102 in //UE5/Private-Frosty/... #ROBOMERGE-BOT: STARSHIP (Private-Frosty -> Main) (v804-16311228) [CL 16412421 by andrew lauritzen in ue5-main branch]
