The Application allows you to choose which rendering engine to use among mental ray® or V-Ray. They are the most used and professional engines in the world, and give you all the power to create stunning and totally realistic images.
If you are upgrading from a previous PRO version (Antares or earlier), you have mental ray® installed; in fact, V-Ray is available just starting from Pegasus version. If you have bought DomuS3D® 2016 PRO, you have V-Ray installed as the default rendering engine. In both situations you can optionally order and activate the second engine. But in this case remember that you need to decide which engine to use before creating a new project, as choosing the engine makes the Application setting up a different set of materials and effects that will be assigned to tiles and objects. We warmly discourage you switching from an engine to the other, once you have already created and settled up the project: graphic results you will achieve may be unpleasant.
In order to decide which engine to use go to the Application Options mask by selecting the command:
File->Options or the command Options in Tools section of the Ribbon.
Get to the Navigation and Rendering Tab and choose the engine you want to use. If the navigation window is currently opened, some of the controls available in the Navigation and Rendering Tab may be disabled.
