Manual sun node- specifies how the VRaySky determines its parameters: Adding a VRaySky as an environment shader will prompt you to automatically create a V-Ray Sun in the scene The VRaySky changes its appearance based on the position of the VRaySun. The VRaySky texture map is typically used as an environment shader for the current pass. Higher values produce smoother results but take more timeĬaustics multiplier - a multiplier for the illumination created by Caustics. Lower values mean more noisy results, but will render faster. Higher values produce smoother results but take more time.ĭiffuse multiplier - a multiplier for the illumination generated by the Global Photon Map.Ĭaustics subdivs - this value is used by V-Ray when calculating Caustics. Photon subdivs - this value is used by V-Ray when calculating the Global Photon Map. This parameter has effect when photons are used in the GI solutions or caustics. This area is represented by the green cylinder around the Sun's ray vector. Photon radius - determines the radius of the area, in where photons would be shot. Specular contribution - a multiplier for the sun effect on specular surfaces. Affect Diffuse - this determines whether the VRaySun is affecting the diffuse properties of the materials.Īffect Specular - this determines whether the VRaySun is affecting the specular of the materials.ĭiffuse contribution - a multiplier for the sun effect on diffuse surfaces.
