Change picframe opacity rhino3/14/2023 Lower values mean more noisy results but render faster. The value determines the amount of involvement.Ītmospheric Shadows – When enabled, the atmospheric effects in the scene cast shadows.Ĭaustic Subdivisions – Determines the number of caustic photons emitted from the light source. When disabled, the light does not cast shadows.Īffect Diffuse – When enabled, the V-Ray Sun affects the diffuse properties of the materials.Īffect Specular – When enabled, the V-Ray Sun affects the specular of the materials.Īffect Atmospherics – Specifies whether the light influences the atmospheric effects in the scene. Shadows – When enabled (the default), the Sun casts shadows. This is useful to prevent bright speckles on glossy surfaces where a ray with low probability hits the extremely bright Sun disk. Invisible – When enabled, the sun becomes invisible to both the camera and reflections. Horizon Offset– Allows the user to manually lower the horizon line. Values close to 0.0 produce a sharper horizon line, while larger values produce a softer horizon line. Ground AlbedoĪlbedo Color – Sets the ground color of the V-Ray Sun and Sky system.īlend Angle – Specifies the angle in degrees where blending occurs between the horizon line and sky. ![]() This parameter is inactive when the Sky Model is set to PGR. Values closer to 0.0 make the sunlight yellow, and values closer to 1.0 make it blue. ![]() Turbidity – Determines the amount of dust in the air and affects the color of the sun and sky. Smaller values produce a clear, blue sky and sun as seen in rural areas, while larger values make them yellow and orange as seen in big cities. This parameter is inactive when the Sky Model is set to PGR. Horizon Illum. – Specifies the intensity (in lx) of the illumination on horizontal surfaces coming from the sky. PRG Clear Sky – V-Ray Sky procedural texture is generated based on the PGR Clear Sky method which has enhanced sunrise and sunset sky. Hosek et al – V-Ray Sky procedural texture is generated based on the Hosek et al. method.ĬIE Clear – V-Ray Sky procedural texture is generated based on the CIE method for clear sky.ĬIE Overcast – V-Ray Sky procedural texture is generated based on the CIE method for cloudy sky. Preetham et al – V-Ray Sky procedural texture is generated based on the Preetham et al. Sky Model – Specifies the procedural model that is used to generate V-Ray Sky texture. This includes the appearance of the sun disc as seen by the camera and of the reflections, as well as the blurriness of the sun shadows. Size Multiplier – Affects the visible size of the sun. Intensity Multiplier – Affects the brightness of the sun and can be used to reduce the default brightness. The intensity of the light still depends on the position of V-Ray Sun in the sky. Override – Sets the color of V-Ray sun to the color in the Filter Color parameter. Instead, intensity is controlled through the Intensity Multiplier. The intensity of the light no longer depends on the position of V-Ray Sun in the sky. Color and IntensityĬolor – Shifts the hue of SunLight system towards the color specified in the field.Ĭolor Mode – Affects the way the color in the Filter color parameter affects the color of the sun.įilter – Shifts V-Ray sun's hue according to the Filter Color parameter.ĭirect – Sets the color of V-Ray sun to the color in the Filter Color parameter. Vertical Angle – Controls the custom sun altitude angle (vertical rotation). Horizontal Angle – Controls the custom sun azimuth angle (horizontal rotation). Custom OrientationĬustom Orientation – Enables custom orientation. Keep picking pairs of image/3D points until you have at least 6 pairs.Enabled ( ) – Turns SunLight on and off. Step 3: Carefully pick a point on the wallpaper image, then carefully pick the corresponding 3D point on the model. Step 2: Click in the viewport with the wallpaper image (to make it the active viewport), and run the PerspectiveMatch command. ![]() Step 1: Open the file with the model in it and put add perspective picture as a wallpaper image in one of the viewports. Or you have modified your model, changed the viewport settings, or want the same rendering projection used to create a previous image … You may need to add more elements to the model to reconstruct a crash or construction scene (for the accident reconstruction bowling pin). You might want to do this to validate that your model really is as accurate as you think it is. You want to set the projection in a Rhino perspective viewport so that the model lies on top of the picture. You have a perspective picture of something and an accurate 3D model.
