How can I reduce rendering noise in KeyShot without increasing render time too much?

Looking for balancing samples, lighting, and denoiser settings.

Key considerations:
• How to optimize sample count vs. render time trade-off
• Best practices for adaptive sampling and progressive rendering
• Denoiser settings (AI-based vs. traditional) and effectiveness
• Lighting setup optimization to minimize noise naturally

Relevant tools: KeyShot's built-in denoiser, AI Engine, and Render Settings panel.
