Setting Up Your Final Render
Now it’s time to create our final renders. To do so, we’ll work with the Render object. We have a few options to tweak in the Lighting section, such as Direct/Indirect Radiance Clamp sliders and Diffuse/Reflection Intensity of the indirect lighting. I recommend experimenting with these options to see what feels good for your render. However, the standard settings are typically good enough.
The next important settings are the Samples and Denoise in the Output tab. We can choose how many render samples per pixel we want with Samples. The higher the samples, the longer it takes to render, which will improve render quality. In my case, I went with 2048 Samples.
The Denoise setting offers both CPU denoising and real-time GPU denoising. When using GPU Denoise, you can expect a smoother ray tracing experience and the ability to navigate your scene without visual artifacts and performance disruptions. CPU Denoising usually provides great render quality using a few samples and works well with fine detail and alpha-blended materials.
In my case, I went with CPU Denoise, set the Quality to High and the Denoise Strength to 0.3. Be careful with the value for Denoise Strength, as you can crunch the details in your texture. Overall, if you go with a high sample count, you should choose a lower denoise strength value; with a lower sample, you should go for a higher denoise strength value.
When satisfied with the results, choose your Output Path, where your rendering should be saved. Ensure your Resolution is high enough, and remember to enable Transparency if needed.
Render Passes & Cameras
You also have the opportunity to create Render Passes like Alpha Mask, Depth, Normals, etc., and render out Material Values such as albedo, roughness, and more. This is handy if you want to composite renders in Adobe Photoshop and fine-tune your rendering. If you use multiple cameras, you could add them to the Render Cameras tab to render everything in one go. I recommend creating a 4K render because having a high-resolution render on hand is always nice. If you have Artstation Pro, you can upload 4K pictures to your portfolio.
