Currently, I’m loading a (rather large) CubeTexture from a .dds file and my application stalls for some seconds after applying it to the environment. Profiling shows that most of the time is spent in
ConvertCubeMapTextureToSphericalPolynomial, which is to be expected, but since the browser is stalling, I have no chance to show a progress bar or any other indicator.
Is there any way to make this process faster or at least more responsive? Can WebWorkers be of any help here?
