Rhino 6 and newer - Global tab
Global tab on Windows (left) and MacOS (right)
In this section, you can set different global options for the render.
Globals | Displacement | Globally toggles Displacement on and off for all the materials in the render. |
|---|---|---|
Dispersion | Globally toggles the Dispersion feature on and off for all the materials in the render. | |
Illumination / Caustics | Illumination | Here you can choose if you want to render the illumination due to Direct, Indirect or Both rays. |
Refl. Caustics | Here you can choose if you want to render the reflected caustics due to Direct, Indirect or Both rays. If the reflections look black, maybe you changed the default option (Both). | |
Refr. Caustics | Here you can choose if you want to render the refracted caustics due to Direct, Indirect or Both rays. If the reflections look black, maybe you changed the default option (Both). | |
Materials | Override | With this option, you can choose a material that will replace all the materials in the scene except for the emitters. It can be convenient to easily create “clay” or “white” renders. |
Default | Set the path for the default .MXM file used for objects that do not have a material assigned to them. | |
Export | Baked Texture Size | Here you can set the size (in pixels) of any Rhino procedural textures that are used in the render. At render time, those textures will be baked to this size and used as any other texture. |
The Illumination /Caustics options won’t change what is internally rendered so it won’t save render time, however, you may avoid showing slow-forming indirect caustics, which would be clean at a very high SL but may show some scarce bright dots at a medium SL.
