This was a great way to achieve a good lighting, but a very high sample count was needed to get a usable result.
In Rhino 6, this was already done by adding the new raytrace mode. This enables fast and efficient implementation of complex lighting scenes with realistic illumination. Unless you take steps to stop it, your Rhino Rectangle light will not only illuminate your V-Ray scene, it will appear (as a rectangle) in that scene! To prevent this from happening, place the light on a layer that is not visiblel, but set the rendering options to include hidden lights.More and more 3D applications are implementing raytracing and other technologies into their renderers. It will only render correctly in one of the rendering plug-ins, as it is harder to render, and it will produce soft shadows and illumination.Īrea lights may emit light from only one side, or from both. Rectangular LightsĪ rectangle light is, as the name suggests, a glowing area of light in the scene, similar to a recessed flourescent ceiling fixture or an indirectly illuminated window. It will only render correctly in one of the rendering plug-ins, as it is harder to render, and it will produce soft shadows and illumination. Linear LightsĪ linear light is, as the name suggests, a glowing line of light in the scene, similar to a flourescent bulb. Again, good ways to light an object, but not so useful if the light is meant to originate at a fixture in the scene. In addition to BounceLight, Rhino has a variety of light-positioning options which use existing cameras or current views to (re)position lights. Rhino then constructs (or moves) a spot light to shine into the model from a point along that normal, and targets it to the point on the surface you indicated. By selecting an object in the scene and a position on the object, you provide Rhino with the information needed to identify a surface normal.
This is a novel way of positioning a regular spotlight. Rhino includes distant, point, and spot lights.
