If Bias is too high, shadows can "detach" from an object. If the Bias value is too low, shadows can "leak" through places they shouldn't, produce moire patterns, or make out-of-place dark areas on meshes. Shadow bias – Moves the shadow toward or away from the shadow-casting object (or objects). This parameter is not available when the renderer is set to GPU. If you specify 0.0, the light is calculated for all surfaces. Larger values cut away more from 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. Rotation X/Y/Z – Rotates the light shape in relation to the target.Ĭutoff – Specifies a threshold for the light intensity, below which the light is not computed. Show distribution – Shows the IES profile distribution as a mesh around the light source in the viewports.
Enabled – Turns the VRayIES light on and off.Įnable viewport shading – When enabled, the effect of the VRayIES light is visible in the viewport.
