You know this effect from looking at a glass of water, or very thick glass.Īir has a refractive index of 1.0 – so light rays travel through it in a straight line -, water has an index of 1.33, window glass 1.52, and, for example diamonds have an index of 2.42 – they bend light quite heavily.įor further information on this topic, feel free to have a look at the Wikipedia article. The Refractive Index slider determines by which factor light is being bent when traveling through a transparent surface. This menu allows you to choose a color that should be added to any semi-transparent areas of your material. If you’re using it combined with a transparency map, it will define the maximum opacity, so white areas on said map will appear as opaque as you’ve set using this slider.
The Opacity slider controls the overall transparency of the surface. If you load a colored image, Enscape will automatically convert it to black and white, so you don’t have to worry about that. Grey areas will appear partially transparent, such as glass. It refers to the Opacity value, so a black area (which equals zero) on the image used will result in a close-to-perfectly transparent portion of the surface, while a white area will appear almost completely opaque. This is how our Plants kil vol 2 is done - you can directly copy blocks that are in the file, so you eliminate the time spent on this process.The Texture parameter allows you to control the transparency using a 2D image, a map. These blocks should be used for scattering. And last thing - Rhino performance - As for now, using Rhinoceros 5 + V-Ray 3.60.03 the most effective way is to convert geometry to proxies and then to blocks. This makes scattering process a bit faster and eliminates the issue with object under the surface. For the Normal orientation - sometimes it's a good idea to mesh the surfaces you want to use for scattering, check normals of these meshes and join them. Then we have to adjust these accordingly. Regarding the Rhino Grow - we use it all the time, however it needs manual refinement after the scatter is done - Plugin doesn't position objects evenly and leaves empty areas, while at some areas, the population is too dense. Hi! First of all, Rhino grow will be obsolete in a few weeks - new scattering plugin is under development and it looks very promising.
