Reflection / Refraction – Enables (default) or disables the calculation of reflections and refractions in V-Ray maps and materials. Glossy effects – Enables (default) or disables the rendering of glossy effects.
SSS – Enables (default) or disables the rendering of sub-surface scattering effects. Global max depth – Enables global limiting of the reflection/refraction depth of a material. When this is disabled, the depth is controlled locally by the materials' Reflection Max depth parameter. When this option is enabled, all materials use the Max depth specified in this rollout. For more details, please see the Global Max Depth example below.
Max depth – Specifies the maximum depth when Global max depth is checked. To disable all reflections/refractions in the scene, set this value to 0. Max. transparency levels – The depth to which transparent objects will be traced. For more details, please see the Max Transparency Levels and Reflection / Refraction example below.
Transparency cutoff – Determines when tracing of transparent objects will be stopped. If the accumulated transparency of a ray is below this threshold, no further tracing will be performed. Allow negative shader colors – Enables the usage of negative values in shaders. This option is useful for including shaders that can accept negative values, such as displacement mapping. |
