1- Setting Up for Success: Camera and Rendering Basics

Choosing the Right Image Format and Resolution

Coohom offers several options for rendering images, with resolutions ranging from 1K to 8K. For test renders, 1K SD is recommended to save time and resources. Once you're happy with your design, you can switch to higher resolutions like 2K or 4K to produce final, high-quality images.

Coohom also provides presets like indoor daytime and nighttime, which are great for quickly setting up your renders. However, the real magic happens when you customize your settings.

Advanced Settings for Better Renders

For optimal results, always check the boxes in the advanced settings. These control important features like noise reduction and light effects, similar to what you might be familiar with from rendering engines like V-Ray or Corona. Checking these settings ensures your renders come out clean and professional.

One key tip: leave the last two advanced settings (which increase rendering time) unchecked unless you are doing a final render. This will save you significant rendering time during test phases.

2- Mastering Light: Balancing Natural and Artificial Lighting

If you are not happy with the premade day and night presets of Coohom, you can customize your scenario from the "add lights" tab on the left side. From there, you can control natural and artificial lights such as the sun and the spotlights.

Lighting is the backbone of any great render. In Coohom, you can control the sunlight by adjusting its intensity, height, and direction. For example, positioning the sun to cast soft shadows across your scene can create a beautiful natural lighting effect.

Adding Artificial Light

Coohom automatically generates lighting based on your design, but manually placing lights gives you much more control. You can adjust the position, brightness, and even the temperature of artificial lights to create a warm or cool atmosphere.

For realistic lighting effects, consider placing rectangular lights or spotlights in strategic locations like the ceiling or behind furniture. This ensures that both natural and artificial light blend seamlessly, enhancing your interior design.

3- Perfecting Your Render: Final Adjustments

Once your camera angle and lighting are set, it’s time for the final render. Opt for a 4K resolution for detailed, high-quality images. Be sure to check the effect settings to reduce noise and enhance the lighting.

Don’t be afraid to experiment—every render helps you improve your skills. Adjust the lighting, change materials, and test different presets until you achieve the perfect balance.

Conclusion

And there you have it—your guide to mastering 3D rendering in Coohom! By experimenting with camera angles, customizing lighting, and tweaking advanced settings, you'll be able to produce high-quality renders that elevate your designs.
