With little time, we had to create Bonaldo Tufty-time sofa in cloth finish. It's kind of hard, even for Marvelous, but I am quite happy with result like this. Courtesy to Veronika
Already playing with Alpha5. Funny my scene didn't render correctly, so I opted for merging into new scene, and than it rendered correctly again. Filtering Yes or No still cause me some confusion, so at the moment, all maps are unfiltered at 0.1 except for bump which is filtered at 0.1 on summed area.
I guess also bidirectional isn't suitable for this type of scene ? It seems impressively noisy compared to simple path tracing, so I guess it benefits only for much complicated lightning ? Little light sources and caustics,etc.

Still incredibly happy for this renderer.

Hi Juraj,
I have been following this feed for quite some time now and got aboard the Corona Ship. Admiring your work. would you mind, sharing your floor material workflow? is that a texture, or elements using railclone or something of that sort. How to apply random texture, if it was made in Railclone. (the material element is not fully supported in Railclone). A quick response with some details is highly appreciated, as I am trying hard to replicate the effect.
Thanks a lot for your time on reading this post. Cheers.
