What about Lumen & Nanite?

Mira doesn't support Lumen and Nanite yet.

We have been actively testing both technologies on a separated branch of the platform with some promising results, but so far the result is still too demanding to apply to the platform.

Let us know if you want to get access to this specific branch.

Work guidelines

  • All textures must be a power of two bases and with the LOD setup.
  • LODs are preferred for big levels.
  • Follow the recommended Organization.
