My Bundle is very large. What can I do to reduce it?Consider optimizing your assets. For example: lowering image sizes, 3D model file sizes, and video quality. If your Bundle is still too large, consider reducing its complexity or splitting the Bundle into smaller, more specific Bundles.
How can I reduce the size of my video files for free?Effective and free compression is available through Google’s algorithms or HandBrake, an open-source program. Contact firstname.lastname@example.org for more specific information about how to reduce your video file size.
I purchased a 3D asset online. How can I view and edit it?Blender is a free, open source 3D editor which can open most 3D file types. It can be downloaded here. It can also be used to export FBX and GLB files for use in the CMS.
Should I use a GLB file or an FBX file?GLB files are generally preferred for Augmented Reality applications due to faster loading, and allow for more information to be stored in a single file than an fbx. However, GLB exportation may optimize your mesh in ways that make it more difficult to edit later. Exporting a GLB file is recommended when you are ready to use your final product in the CMS. For some 3D editors, a plugin may also be required to export a GLB file, whereas FBX exportation is more widely supported.
What is the difference between a GLB file and a glTF file? Which one do I use?Both formats are similar, but only GLB files are supported on the CMS. A GLB file is essentially a glTF file with embedded textures.
Why are parts of my GLB mesh black when viewed in the app?Due to the nature of glTF files, meshes with hard-shaded edges will have their faces split apart. While this does not usually cause a problem visually, it is important to test your model in an Experience before release to ensure the look is correct. If you are seeing unintended black portions in your mesh, open the mesh source file in your 3D editor of choice and convert any quadrangle faces to triangles, then re-export. Alternatively, switching the shading type to smooth or exporting your mesh as an FBX file after checking for duplicate vertices should resolve this issue.
How can I make my 3D asset’s file size smaller?Generally, the lower the polygon count and texture resolution are the smaller the file will be. Contact email@example.com for more specific information about how to reduce your 3D file size.
Why is my 3D model not visible in the scene?There may be scaling and positioning issues. Import the model into your 3D Editor of choice and ensure the pivot of your object is properly placed.
Why does my model appear much larger or smaller in-app than in the CMS?The model’s center may not be set correctly. Open your model in a 3D editor and ensure all transformations are applied to its pivot. In Blender, you can do this by selecting your model and clicking “Apply” > “All Transformations to Delta.” In Maya, you can do this by selecting your object and clicking “Modify” > “Freeze Transformations.”
