To reduce the image texture size of a glb model, you can either covert to a gltf file, so that there is a folder with all the texture files and reduce the size of the image textures using a tool like photoshop (reduce the size of the images by half, or by a quarter for example). You can use a tool like Blender to do this. However, if you want to improve the performance of another downloadable model, you can either reduce the objects texture size, or you can reduce the number of triangles. Typically the more realistic a model appears, the more complex the model is (although this is not always the case).ģD models found using the Sketchfab and Google Poly browser in Spoke and Hubs are already filtered based on objects' sizes/complexity. Two main factors contribute to an object's complexity, firstly, the texture assets in a model, secondly, the number of triangles in the model itself.

Convert GIFs to video format, as they run more efficiently in Hubs.Ĭomplex 3D models can cause performance challenges in your scenes.jpeg, as these often have smaller file sizes. Compress the files, use the 'save for web' feature in Photoshop for images, or use an online image or video compression tool to reduce the file size.Reduce the dimensions of large images/video.

If you are including a lot of this type of media in your scene, you can do the following to maintain good performance. Very large, detailed images and videos can reduce performance on the web. This will show you additional information on the load time, number of triangles, and textures in your scene. Click on the FPS meter in the lower right hand corner on desktop (or in VR, type /vrstats into the chat box). To take a closer look at your scene's performance, you can open up the VR Status menu. In the following section we will briefly cover steps you can take to optimize your assets. This could involve reducing the number of objects in a scene or optimizing the assets you are using. One way to improve performance for everyone is to reduce the complexity of a scene. From high-powered wired-in VR headsets, to low-powered mobile phones performance of a scene may vary based on the type of device and connection speed of a your visitors. When building Hubs scenes, you'll most likely want them to perform well across a wide-range of devices.
