There are also hard limits on the total number models, vertices, and meshes that can be open simultaneously in 3D Viewer Beta (see File and model limitations). Animations can have an impact on the performance of other open models. 3D Viewer Beta will show a warning on load if there are more than 150,000 vertices or more than 400 meshes. There are many variables in a 3D model that can impact performance. 3D Viewer Beta renders content real-time and performance is subject to HoloLens hardware capabilities. Keep performance in mind while authoring content and validate in the 3D Viewer Beta app on HoloLens during the authoring process for best results. This can cause the model to jitter while being moved/scaled/rotated. Avoid very large translation offsets between nodes (for example, 100,000 units).Before exporting to FBX from your creation tool, ensure all geometry is visible and unlocked and no layers that contain geometry are turned off or templated.Holograms are made of light, thus HoloLens renders black (the absence of light) as transparent. Avoid black materials or black areas in texture maps.Optimizing 3D models for 3D Viewer Beta Special considerations Meshes: 1,600 combined on all open models.Vertices: 600,000 combined on all open models.There are hard limits on the size of files, as well as the number of models, vertices, and meshes that can be open simultaneously in 3D Viewer Beta: Supported material properties for Phong.Supported material properties for Lambert.Lambert and Phong materials are supported, with adjustable parameters.Skeletal (rigged) animation with skinning.Scale/rotation/translation animation on individual objects.Alpha channel in diffuse textures causes pixels to be discarded if below 50%.Maximum of one diffuse map, one normal map, and one reflection cube map per mesh.
Maximum texture resolution of 2048x2048.TGA images (24-bit RGB and 32-bit RGBQ true-color).Texture maps must be embedded in the FBX file.Shear in transformation matrices is not supported.Supported content specifications File format If you're having trouble after reading these topics, see Troubleshooting below. See Viewing FBX files on HoloLens below to learn more. There are two ways to open a 3D model on HoloLens. To build or optimize 3D models for use with 3D Viewer Beta, see Optimizing 3D models for 3D Viewer Beta below. If you're having trouble opening a 3D model in 3D Viewer Beta, or certain features of your 3D model are unsupported, see Supported content specifications below. While 3D Viewer Beta may remain available in the Microsoft Store for HoloLens (1st gen), it is no longer in active development and is no longer supported.
