Is it possible to manually set mipmaps for CubeTexture?

Hello,

I’m trying to manually set mipmaps for CubeTexture. I pushed image objects to mipmaps property of CubeTexture, but it doesn’t work at all. I saw an issue on Three.js’s Github, which says that there is a solution for that, but I think it’s not possible yet. Do you have any clean solution for this problem?

Best regards
