![]() ![]() * Currently not compatible with RT-Rendering! GRay is not really stable and throws exceptions from time to time, so note that I am not responsible for any damage caused by this plugin. This will automatically create a mp4 video and a high quality gif. Just unpack the ZIP next to your saved GH file or copy the ffmpeg.exe to your "C/Windows/System32" folder. FFMPEG is a handy video encoder which can be downloaded here (Windows Build 32 or 64 bit): Optionally, you can use the FFMPEG extension. You can find your renderings in a subfolder next to your Grasshopper file. See the example files for more information. I recommend to stay under 200 (depending on your hardware), which can be achieved by making Branches of geometry for each material. So beware of using too much materials, this can expand your render time. Basically this plugin writes vrmat files and loads them to your scene. The functions of the first version are limited to Standard Materials. Please read the instructions below! Join the Grasshopper board group for support. It gives you the ability to render your generative geometry directly from Grasshopper. GRay is a Parametric Material Generator for the Rhino Render Plugin V-Ray, with a flexible and easy to use interface for single renderings as well as animation. No bounce lighting, just general ambient light paths.Generative Materials for V-Ray 2 and V-Ray 3 It literally just lays the colors and textures directly on it so everything looks flat. The “Diffuse filter” is basically just textures and colors with no lighting, no shadows, no bounce light, nothing. If you were to use the Vray sky, you would get an alpha because that one is transparent. The Vray dome is opaque, which is why you don’t get an alpha. Next is “Alpha.” There’s only a tiny bit of Alpha here. To do that, go to “Select > Color Range” and click on the grass with the eyedropper tool, then hit OK and you will see all of the grass is selected. So if you want to work on just the grass, you can just do a selection by color. “Material ID” is good for selecting different pieces. So this will be great for enhancing the interior if it’s dark. Glass is really the only transparent object in this particular scene. But you can see it’s really just the refraction layer, so it’s showing you what’s behind every transparent object in the scene. Next is “Refraction,” this one has the filter and the refraction built into it. So you can select the black, invert, and delete the sky if you want to swap it. What this is helpful for is that this is a really good mask for your sky because everything is black except for the sky. It looks like this because we are using the Vray dome, and the dome is self-illuminated objects, and this channel is picking that up. If you render with the Vray sky, this wouldn’t look like this. “Self-illumination” – this is the Vray dome. You can see where the light is and where the shadows are. “Shadow” is just the shadows information. This is useful if you want to use it as a depth of field channel or tool. The closer the objects are to the camera, the darker they will be, and the farther away they are, they will be white. You can see the file titled “ZDepth” is giving you information about how far the objects are away from the camera. So let’s look at all of those render passes and channels. And if you spend 45 minutes to an hour getting to this point from scratch, that’s great because then you can spend another 30 minutes or so tweaking it using all of these other render passes and render channels. The colors might not be perfect, the lighting may need a little bit of work, but it’s a great base. This tutorial is part of the Black Spectacles course on 3D Rendering with Vray 3.2 for SketchUp and Rhino 5 in which you will learn how to bring a 3D model into Vray for SketchUp 216 and Rhino 5, render it out, and touch it up in Photoshop to give your final image a professional finesse.īringing Rendered Channels into Photoshop TutorialĪ good rule of thumb is to try to create a rendering out of the box that will probably be about 80% complete. In this Black Spectacles free tutorial, you will learn how to bring rendered channels and rendered passes into Photoshop.
