It’s common to split out many aspects of the render into different parts like specular, reflection, reflection filter, diffuse filter, lighting, and global illumination.
In the visual effects world, artists will output a large number of render elements to allow for adjustments in compositing. But it does have some limitations that keep it from being the best solution for final renderings. Because it gives users a near real-time denoised solution, it’s a great option for lighting and scene composition. In an earlier blog post, we explained the pros and cons of the new NVIDIA AI Denoiser that’s in V-Ray Next. And rarely does one solution fit all cases. Denoising is a relatively complex problem.
