debugBlackboardTexture method
A raw pipeline texture by blackboard key (ssao_texture,
bloom_texture, selection_mask, ...), for debug visualization
overlays. Null when the frame did not produce it, or unless the host
opted into render-graph debugging (Scene.debugAllowRenderGraphCapture);
the named getters above remain the supported surface for real effects.
Implementation
gpu.Texture? debugBlackboardTexture(String key) {
if (!RenderGraphDebug.enabled) return null;
return _context.blackboard.get<gpu.Texture>(key);
}
