CubeMap is a software package designed for convert the texture of the cylindrical projection to the quadrilateralized spherical cube projection (cubemap projection). It is support input textures of any resolution, any number of channels per pixel, 8-bit or 16-bits signed or unsigned integers. The format of the input texture is uncompressed raw data. The format of the output texture is raw and/or array of tiles with different levels of detail in formats of raw, tga, dds, jpg or png. Please read readme_eng.txt for instructions.
I got the same message. Windows 10 DOES NOT like this download. First SmartScreen Filter didn't like it. I disabled that to download it, then Windows Defender keeps picking it up. Can't find a workaround for that. I wanted the planets, but I guess I'll either have to keep working at it or wait until this is Windows 10 friendly.
Software that takes well but entered the raw formats and we now cover no more free raw converter, it became free (proof my free internet converter passed in fee). Hopefully soon, it may take any other format like jpg, png on input.
