![]() The reason is that when inside SketchUp, objects are combined into a single component, but when they are exported into FBX, these components are separated into thousands of individual objects and nodes. SketchUp objects slow down FPS in UnityĪnother common issue is that when SketchUp objects are imported into Unity, they are heavier to process and render. Dealing with bad geometry in Unity can be very time consuming and delay your visualization project. These include bad UV’s, duplicate normal, and inverted vertices. However, issues can arise when exporting your entire SketchUp model, including objects that were added from Maya, into FBX. ![]() For example, you may add furniture models from Maya into your SketchUp model. Errors exporting objects that were not originally from SketchUpįor many SketchUp users, it’s common practice to import objects from other 3D software (like Maya, 3ds Max and Blender) into their SketchUp model. ![]() Common issues when importing SketchUp into Unity 1. This post will go over common issues users face when importing SketchUp into Unity, tips on how to fix them, and a new automated solution called Meshmatic. And while users can now import SketchUp files directly into Unity, they still face issues with textures, duplicate assets, low FPS, and scaling. Once done, the model should have all the materials and textures added to it.SketchUp is one of the most used software for architectural modeling. Do the same for Materials by clicking on the “Extract Materials …” and creating a new folder called “materials”. Create a new folder in the pop-up window and rename it to “Textures”, and then click on “Select Folder”. ![]() To fix this, click on the “Extract Textures …” button in the inspector panel. You can see that in the inspector menu it is detected that this is a SketchUp model, but all the materials for the individual components of this model are missing (labeled as none). Select the prefab of the model you have imported into your folder. To fix this problem, we need to extract all the materials and textures from the prefab of the model so that Unity knows how to map them. If the above method does not work for your case, you can always simply add the skp model into the editor by dragging and dropping it into the folder structure. You may have noticed that the Building object we have imported looks rather dull and is missing lots of textures and materials. ![]() Selecting it will show a preview and settings for importing the model into the Scene in the Inspector Window. The asset for the Old Main 3D model itself will appear under the name “OldMain” as an icon with a little arrow on the right side. The two folders called “Materials” and “Textures” contain the components required to render the Old Main model. If you look in the Assets pane of the Project Window, you will see that several things have been added there in addition to the SampleScene. Unity will immediately recognize the new file in the Assets folder and import it. 4.2 Start Unity again and open the “MyFirstUnityProject” project.4.1 Copy the downloaded file OldMain.skp into the “Assets” folder under “…Documents\UnityProjects\MyFirstUnityProject” (adjust the location where you have saved your project if it's not in Documents).Before that, please make sure that neither Unity nor SketchUp are currently running! Then perform the following steps: So we are simply going to put the downloaded. ![]()
