Sketchup make image transparent4/28/2024 ![]() Wherever possible, we recommend taking advantage of this by making any repeating elements in your scene (such as windows, doors, or chairs) into reusable components in SketchUp.ĭatasmith exports rotating billboards from your SketchUp scene as flat Static Meshes, and places instances of these flat Static Meshes into the Level. This is typically better for the runtime memory requirements and performance of your Project, as well as making it easier to manage the number of Static Mesh assets in your Content Browser. When Datasmith detects multiple copies of the same component in your SketchUp scene, it only creates one set of Static Mesh assets for that component, and places multiple instances of those Static Meshes into the scene. If this happens, you can try splitting your large geometries across multiple components or layers in SketchUp to make the Static Meshes easier to deal with in Unreal. Depending on the way your lightmap UVs are laid out, you may not be able to generate good results at all. You can try increasing the lightmap resolution on the large Static Meshes, but this also increases your baking time and runtime memory requirements. Large meshes require correspondingly large lightmap textures in order to make sure that each part of the model has an adequate amount of texture space to record its light and shadow. If your Static Meshes in Unreal are very large, you may have trouble achieving good results when baking static or stationary lights for your scene. Knowing this strategy can help you influence the Static Meshes it creates. ![]() ![]() To read more about other types of Datasmith workflows, seeĭatasmith Supported Software and File Typesĭatasmith divides your SketchUp geometry into Static Mesh assets by combining all connected polygon faces that are in the same component or group, into a single Static Mesh. This way, you don't need to manually re-import the entire scene into Unreal Engine every time you want to make a change. To preview changes to your SketchUp scene in Unreal Engine in real time, you can set up a Datasmith DirectLink between the two. # This creates a C:\temp\hello.udatasmith file. Sketchup.open_file 'E:\path\to\file\sketchup_file.skp'ĮpicGames::Datasmith.export "hello", 'C:\temp' You can also export a single file from code. Puts "Exporting '#'"ĮpicGames::Datasmith.export name, target_dir Path = File.join source_directory, filename To export all SketchUp files from a given folder, run this code:ĭir.foreach(source_directory) do |filename| Once you install the Ruby Code Editor extension, you can access it from SketchUp's main menu: For instructions on how to do that, see the SketchUp documentation on ![]() This helps automate your pipeline.īefore you can do this, you need to install theĮxtension for SketchUp. You can run a Ruby script in SketchUp to batch exportįiles. Importing Datasmith Content into Unreal Engine 4 Importer available in the Toolbar of the Unreal Editor to import your Plugin for your Project, if it's not already installed. If you switch to a different version of Unreal Engine, make sure you download and install the matching version of the plugin.Įxporting Datasmith Content from Sketchup Pro In this animation, the red ColorSource Linear fixtures are washing the outside of the walls while the blue fixtures are illuminating the inside face of the walls.Epic releases a new version of the Unreal Datasmith Exporter plugin for SketchUp with every new release of Unreal Engine. Augment3d uses this to our advantage with the stock walls so that you can be zoomed out far enough to see the entire space but not have a wall blocking your view into the venue. Other times, a program that does not perform backface culling may not set normals correctly (or how you would expect) on export because it doesn't look at that information in its own presentation.įinally, some objects intentionally have their normals pointing inward so that when you are outside the object you can see into it, but when you are inside the object, the faces appear solid. However, if a plane was extruded into a three dimensional shape, the face on the back side of that new object may not invert its original normal.Įxample: This three dimensional board appears as a box due to how it was extruded. Generally, when an object is drawn in a 3D environment, the normals are set to face away from the center of the object so that the object appears solid.
