Light bulb vray rhino how to#
Adjust your camera for better focus and how to set the DOF.Soften sharp shadows by changing the intensity of the V-Ray Sun.Make a test render using the V-Ray Frame Buffer and review your test renders.Change the camera parameters including ISO, f-stop and shutter speed.Place Portal lights correctly in the scene and group them.Optimize and speed up the rendering process using Portal lights.Change the sky color by moving the light.Use the V-Ray Sun to light up the scene (and how the V-Ray Sun & Sky features work together in the system).
Set up the correct camera view and lock it.In part 1 of video 1 (above), Fabio reveals how to: The irradiance map can also be saved for later use.Part 1: Using the V-Ray Sun & Sky system for daytime interior lighting The result is that the irradiance map is computed more slowly but the rendering takes less time. Store With Irradiance Map– When enabled and GI calculation is set to Irradiance map, V-Ray calculates the effects of the V-Ray Ambient Light and stores them in the irradiance map. When this value is 0.0, the light is calculated for all surfaces. Larger values cut away more of the light lower values make the light range larger. This can be useful in scenes with many lights, where you want to limit the effect of the lights to some distance around them. Higher values produce smoother results but take more time.Ĭut-off Threshold – Specifies a threshold for the light intensity, below which the light is not computed. Lower values mean more noisy results, but render faster. Note that this multiplier is cumulative - it does not override the multiplier in the Caustics Tab of the V-Ray Render Settings.Ĭaustics Subdivs – Only used when calculating Caustics. Motion Blur Samples –Specifies the number of samples used to sample the light for motion blur.Ĭaustics Multiplier – Specifies a multiplier for the generated caustics by the selected object.
Specular Contribution – Specifies a multiplier for the effect of the light on the specular component. This means glossy reflections.ĭiffuse Contribution – Specifies a multiplier for the effect of the light on the diffuse component. Illumination Mask – Specifies what objects to be lighted by the V-Ray Ambient light.Īffect Diffuse – Determines whether the light affects the diffuse properties of the materials.Īffect Specular – Determines whether the light affects the specular of the materials. A value of 0 shows light coming from all direction, while a value of 1 shows the light coming only from the direction of the light. When this setting is used, the intensity of the light depends on its size.Ĭolor – Specifies the color of the Ambient Light.ĭecay – Controls the behavior of the light intensity in relation to the distance of the light source.Īmbient Shade – Controls how the ambient light appears in the scene. W/m/m/sr – Visible light surface power measured in watts per square meter per steradian.
A typical 100W light bulb only emits between 2 and 3 watts as visible light. Keep in mind that this is not the same as the electric power consumed by a light bulb for example. When using this setting, the intensity of the light does not depend on its size. Watts – Total emitted visible light power measured in watts. When this setting is used, the intensity of the light depends on its size. Lm/m/m/sr – Visible light surface power measured in lumens per square meter per steradian. A typical 100W electric bulb emits about 1500 lumens of light. When this setting is used, the intensity of the light does not depend on its size. Lumens – Total emitted visible light power measured in lumens. The light surface appears with the given color in the final image when seen directly by the camera (assuming there is no color mapping involved). The possible values are:ĭefault – The color and multiplier directly determine the visible color of the light without any conversion. The light automatically takes the scene's unit scale into consideration to produce the correct result for the scale you are working with. Using correct units is essential when using the V-Ray Physical Camera. Intensity– Multiplier for the light strength this is also the light intensity in the units set by the Units parameter. These parameters can be found in the V-Ray Light tab of the parameters editor.
