![]() Ray traced.įorce Ray Trace: When enabled for a 3D object, its surfaces will be ray traced at render time, even if Ray trace objects is disabled in the Renderer settings. It is useful when you have some objects you want to render with displacement but you don't want to change how all the rest of your objects are rendered, i.e. When the object's render method is set to Default, the object is rendered according to the Ray trace objects setting in the render node.įorce Displacement: When enabled for a 3D object, its surfaces will be subdivided into micropolygons at render time, which allows the 3D geometry to be displaced correctly but at the expense of slightly longer render times. When displacement is applied to a 3D object the render method should be changed to Force Displacement. Typically it results in higher quality and faster rendering. Show b-box in preview: When checked, the bounding box of the Sphere shape will be displayed in 3D Preview.ĭefault: Ray Tracing is the default rendering method for an object.Enable: When checked, the node is active and the Sphere object will appear in the scene with the settings below applied to its surface.Name: This setting allows you to apply a descriptive name to the node, which can be helpful when using multiple Sphere nodes in a project.This useful shape is also the basis for the Background object in the default Terragen project. Examples of populateable objects are the Card, Grass Clump, Poly Cube, Poly Sphere, Rock, and imported geometry in TGO/OBJ/LWO formats. Note that populations may need an extra repopulation step. While these objects can also update within the 3D Preview in non-RTP mode, ideally the RTP mode is better suited for populatable and ray traceable items. They render faster, especially with reflections or in the Path Tracer, and have better motion blur and depth of field due to ray tracing. ![]() These objects cast very precise shadow, reflections and subsurface scattering. On object nodes with displacement features implemented they rely on per-vertex/Mesh displacement in object space prior to instancing. Populatable objects can be instanced via a Populator node. Examples of displaceable objects are the Cube, Disc, Lake, Octahedron, Plane, Planet and Sphere objects. Displaceable objects update within the 3D Preview in non-RTP mode. By using Transform shaders, colour and other shaders can also take advantage of the worldspace texture coordinates. Worldspace texture coordinates are used for displacement, making these types of objects ideal for building world environments. In Terragen, 3d objects fall into one of two categories “Displaceable” or “Populatable”.ĭisplaceable objects rely on micropoly displacement at render time, which adapts to distance, resolution, etc. The Sphere node creates a spherical object.
