The Options allow you to control various aspects of the renderer globally.
Geometry
Scene units - here you can setup scene units, it madded for quick setup, and to save parameters with file. For
VRAYforC4D important to work with normal scale, for example chair can be 75 cm=750mm=0.75m etc...
Lighting
Lights - enables or disables lights globally.
Default lights - enables or disables the usage of default lights. When this is
On, lights are rendered regardless of whether they are hidden or not. When this option is
Off, any lights that are hidden for any reason (either explicitly or by type) will not be included in the rendering, option
Off with GI account
GI.
Shadows - enables or disables shadows globally.
Show GI only - when this option is on, direct lighting will not be included in the final rendering. Note that lights will still be considered for
GI calculations, however in the end only the indirect lighting will be shown.
Photometric scale - this parameter allow to compensate exposure for non physical camera renders.
Indirect illumination
Don't render final image - when this option is on,
VRAYforC4D will only calculate the relevant global illumination maps (photon maps, light maps, irradiance maps). This is a useful option if you are calculating maps for a fly-through animation.
Reflection / Refraction - enables or disables the calculation of reflections and refractions in
VRAYforC4D maps and materials.
Limit ray depth - enables the user to limit globally the reflection/refraction depth. When this is unchecked, the depth is controlled locally by the materials/maps. When this option is checked, all materials and maps use the depth specified in Max depth.
Max depth - enables the user to limit globally the reflection/refraction depth.
Maps - enables or disables texture maps.
Filter maps - enables or disables texture map filtering. When enabled, the depth is controlled locally by the settings of the texture maps. When disabled, no filtering is performed.
Max transparency levels - this controls to what depth transparent objects will be traced.
Transparency cutoff - this controls 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.
Glossy effects - this option allows the user to replace all glossy reflections in the scene with non-glossy ones; useful for test renderings.
Override material - this option allows the user to override the scene materials when rendering. All objects will be rendered with the chosen material, if one is selected, or with Default surface color materials if no material is specified.
Overriding material- this option allows to choose material that will be use for overriding scene materials. Just drag and drop here vray material from
Materials Manager.
Default surface color - color that replace all the scene materials when rendering, if no Overriding material is assigned.
Raytracing
Secondary rays bias - a small positive offset that will be applied to all secondary rays; this can be used if you have overlapping faces in the scene to avoid the black splotches that may appear.
Geometry back face cull - enables or disables (default) back face culling for camera and shadow rays. When this option is on, the surfaces of objects which are turned away from the camera (or the light source, when tracing shadows) will appear fully transparent. This allows to look inside closed objects when the camera is outside.
Miscellaneous options
Optimized atmospheric evaluation - turning this option on will cause
VRAYforC4D to first evaluate the atmospheric effects, and shade the surface behind them only if the atmospherics are sufficiently transparent.
Low thread priority - turning this on will cause
VRAYforC4D to use threads of lower priority when rendering.
Stamp Vray informations - the frame stamp is a convenient way to put some short text over the rendered images. It can be useful in many ways - for example, in network rendering, to quickly determine which frames were rendered by which machine. The frame stamp is one line of text, which appears at the bottom of the image.
Total Triangles - the number of unique intersectable primitives, such as a triangle, generated for the current scene.
Label - here you enter the text you wish to appear in the images.
