How To reduce the 3D model file size for VR
Steps for optimizing in general the file size of a 3D model for VR . Remove unused assets, scripts, and shaders: (Manually or use the script editor) . Remove unnecessary geometry : (Manually or use the decimate modifier or polygon reduction tool) . Optimize mesh geometry: (Manual Retopology or use the Decimate Collapse and Undivide options. Bake the high-poly details onto a low-poly texture using tools like Substance Painter or Marmoset Toolbag. For complex meshes with many polygons, use the Mesh Deformer tool to compress the mesh by reducing its size while maintaining its shape.) . Optimize materials : (Use instances not duplications) . Use texture atlasing : (Manually in UV layout or use texture atlas generator tools) . Resize textures and enable mipmapping: (Mipmap genrates smaller textures for distant models) . Use compressed texture formats: (Use DXT, ETC, or ASTC for better compression ratios) Utilize level-of-detail (LOD) systems: (Manually create multiple version...
