A pure black color will be fully transparent in Lumion and a pure white color will not be transparent at all. You can skip steps 1.1-1.3 if you do not need to add a transparency mask.ġ.2: Then paint the Alpha Channel with grayscale tones. External Link: Adobe Photoshop Help: Create and edit alpha channel masks.PureGlass and the Standard Material support 16 levels of transparency when rendered as a Photo or in Movie Mode as a 4 Star Output Quality.ġ.1: If you are using Adobe Photoshop, please click on the link below to see how to add an Alpha Channel to an image: Please note that the standard Glass Material is the only material that supports a transparency mask with 256 levels of transparency. That way you can make some parts of the texture more or less transparent than others. 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.It is not possible to add your own textures to PureGlass materials, so you'll have to use the standard Glass Material if you want to add a texture to the material.Ī transparency mask can be added to the Alpha Channel of the texture if you save it as a 32-bit PNG, TGA, TIFF, or BMP texture. 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.
