![]() The prop disc texture is used by dividing it into equally sized cells horizontally and vertically and then selecting a cell. ![]() ![]() (The side billboard is not used unless a plugin activates it.) The front disc is a quad normal to the longitudinal axis the side billboard is a quad normal to the lateral axis. The prop disc is made up of two parts: the front disc and the side billboard. When the prop is not a disc, X-Plane will draw an airfoil for each blade, unless the plane part is disabled for drawing in Plane-Maker. In disc mode the physical prop is not drawn – instead one or two proxy textures are drawn to simulate the effect of the prop spinning rapidly. The idea is to allow a plugin installed in an airplane to provide the rules for prop disc rendering, while letting X-Plane deal with the details of z-buffer thrash and other prop-disc-related artifacts.Īuthors who want detailed 3-d props (when not spinning) should continue to build these with a 3-d modeler and turn off the “draw plane part”.Ī sample plugin that controls the prop disc datarefs can be found here: //You can download a sample airplane with a custom prop disc driven by a plugin here: File:Example prop disc.zip. ![]() X-Plane 940 allows you to customize the look of the prop disc using a series of datarefs.
