3D Model Optimizations

  • The model should be scaled to real life sizes and the origin point should be at the center of the model before exporting.
  • For the model to be efficient, the poly count should be kept as low as possible. All the textures exported should go through a compression pass using online compressor tinypng.com or similar.
  • Lower the size of the model, the better would be the loading speed.
    • Ensure the number of vertices/triangles/polygons is as low as possible.
    • Ensure textures are compressed
    • Bake the textures into the model. Keep textures less than 4k resolution.

3D Model Details and File Size Recommendation​

Recommended Max Triangles Count
Recommended Max File Size
50K
50MB
The above recommendation is for the whole scene. This is, less than 50k triangles, 50MB file size in total for a scene (i.e. the sum of all triangles/file sizes for all 3D Models in a scene).

Steps:

  • Decide to combine all objects or do them as individual objects
  • Texture your model correctly with properly unwrapped UVs - no overlaps
  • Setup good lighting and test it in quick render modes
  • Bake and export textures
