Is Render Denoiser available in Rhino 6?

Hi there,

Can I ask if the render denoiser available in Rhino 6 as form of a plugin?

sadly no, v7 only-

There are other render engines for rhino that do include a denoisers. But, the denoiser we have is tuned for pathtracer style rendering which is only available on rhino 7 built-in cycles renderer.
