This is typically better for the runtime memory requirements and performance of your Project. It then places multiple instances of those Static Meshes into the scene. When Datasmith detects multiple instances of the same block in your Rhino scene, it only creates one set of Static Mesh Assets for the geometry in that block. Installing the Datasmith plugin adds a dockable toolbar in Rhino. To read more about other types of Datasmith workflows, see Datasmith Supported Software and File Types. For more information, see Using Datasmith Direct Link documentation. This way, you don't need to manually re-import the entire scene into UE4 every time you want to make a change. To preview changes to your Rhino scene in UE4 in real time, you can set up a Datasmith DirectLink between the two. See Importing Datasmith Content into Unreal Engine 4. Use the Datasmith importer available in the Toolbar of the Unreal Editor to import your. See Exporting Datasmith Content from Rhino. See Installing the Datasmith Exporter for Rhino.Įxport your Rhino content using the Save As or Export process. Install the Datasmith Exporter plugin for Rhino. This means that to get your Rhino content into UE4 using Datasmith, you need to: If you plan to use Datasmith to import scenes from Rhino into Unreal Editor, reading this page can help you understand how your scene is translated, and how you can work with the results in Unreal Editor.ĭatasmith uses an export workflow for Rhino. It follows the basic process outlined in the Datasmith Overview and About the Datasmith Import Process, but adds some special translation behavior that is specific to Rhino. Use this to optimize the viewport performance.This page describes how Datasmith imports scenes from McNeel Rhinoceros (Rhino) into Unreal Engine 4 (UE4). Preview Percentage – Limits the number of previews displayed in the viewport. Note that the point positions are determined by the origin of the guest. Preview Mode – Changes between a Bounding Box or Point Preview for the instances. Object origin – The original object origin point snaps to the instance point. Guest Origin – Determines how the objects are positioned relative to the random Scatter points.īounding box bottom center – The bounding box bottom center of the object is matched to the instance point.īounding box volume center – The bounding box volume center snaps to the instance point. For more information see the Probability Example below. Probability – Determines the relative probability of the guest to appear. The objects in this list are scattered on the base geometry. Eliminating collisions will reduce the initial density count and may alter the predetermined ratio between multiple guests.Īdd Guests – Adds the currently selected scene objects to the Guests list. World Up – All instances are positioned upright independent of the base/host surface face normals.Īlong Normals – The instances are oriented based on the base surface face normals.Ĭollision Detection – When enabled, instances with overlapping bounding boxes will be discarded. Orientation – Specifies the initial orientation of the instances. Note that host component transformations are ignored. Change this integer value to get a different random distribution.Īxis Filter – Filters the faces that will be used for instance positioning.Īll Faces – The points/instances are generated uniformly on all object faces.įacing Up – The points/instances are only placed on object faces oriented upwards in the scene. Seed – Controls the random seed of the Scatter. Areas colored with white receive maximum density. Black color in the texture discards all instances in the area. When a texture is used, the density value can still be used. Density – Determines the approximate count of instances in a square meter.
