Here, Im going to create a gravel texture that Ive downloaded from CGBookcase.There are many new features, including SubD tools (previously only available to users of the now defunct plugin T-Splines or otherwise in applications like 3ds Max, Maya, Blender and ZBrush), Rhino.Inside.Revit (run Rhino and Grasshopper within the BIM modeller Revit), QuadRemesh (quickly create a quad mesh from NURBS geometry or meshes), new Rhino 7 Presentation tools and much, much more.
This includes the Cycles Raytrace Render and how we can add Denoiser elements with the new Package Manager in Rhino 7. ![]() This Raytraced or Cycles mode allows for proper calculations of Reflections, Transparency, Refraction, Translucency etcetera. This Raytraced view mode, whilst being a live mode, does take some time to generate and here because of time limitations Ive reduced the number of Render passes from 1000 to 500 and speeded up the video. Essentially these are graphics cards that are purpose built for accelerating Ray Tracing and we hope to be looking at these in the new year with the help of PNY Europe, but for now were using NVIDIA CUDA acceleration. The Render tab here on the right is where you set your variables for the Render, so for example, the output size, the quality settings, Ground Plane and Environmental Settings. So, Ill hit the Render button and well see the Render Process start and the Frame Buffer window appear and this will also confirm that Im using my Quadro card for acceleration its worth noting that rendering this way should be more efficient than rendering in the Raytraced Viewport. If you are familiar with V-Ray or KeyShot then youll know that these now feature Denoiser components that can help to clean up this noise meaning that we can get viable results with less render passes. The good news is that there are now Denoiser components available for Cycles in Rhino and also that these work really well. From my New in Rhino 7 tab Ill select Package Manager and once this is launched Ill search for Denoiser and youll see I have two denoiser components that I can use on this particular machine an Intel Denoiser and an NVIDIA Denoiser. Its also worth making sure that your NVIDIA graphics card driver is up to date in order to run the NVIDIA Denoiser. ![]() Ill go over to my Render Panel and choose Viewport Resolution and Good Quality and leave the other settings at pretty much Default and Ill hit the Render button so we can see the render starting to progress now, going through the various passes, and Ill just leave it to render out a few more samples and then we can look at the noise. These are all the Post Effects that I can add and Ill add the Intel denoiser back in again. So, lets start with the Intel denoiser Ill apply that and youll see how it smooths out the noise and if I turn it off again youll see that the noise comes back. The NVIDIA Denoiser is, of course, going to use the GPU and were already rendering with the GPU this builds and behaves slightly differently to the Intel Denoiser but the overall effect is pretty much the same, so again smoothing out that noise. At the moment the render has only done a few passes, and you can see that perhaps too much detail is being lost and we wont be able to resolve that detail until weve done a few more passes but you get the general idea here that this is a really good way of being able to produce a viable Raytrace render in much shorter order i.e. The result is very similar to the Denoiser that we see in V-Ray for example. In windows we can use GPU for accelerating the render and for denoising if youre using a Mac, however, then there is no GPU acceleration for rendering and the only denoiser you can use is the Intel component however as you can see here Cycles makes full use of all the available CPU cores on a Mac and the Intel denoiser is very effective in reducing Raytrace render times. Physically Based or PBR materials are a compact format that allows a single material type to define materials that would usually need separate definitions so for example, diffuse, glossy, specular, dielectric, metals, etcetera. Physically Based Materials can be considered as being platform agnostic and cross platform and youll see that they are popping up now in many popular programmes such as V-Ray and Unreal. Rhino Rendering Plugin Free And AnWe can create these materials from scratch but theres an increasing amount of materials available online many of these being free and an example of this would be CGBookcase.com when we download a material it will often have a series of Texture Maps that are used to create the Physically Based Material.
