Preferred format
DDS is the preferred format for texturing 3D Models.
A DDS file can contain compressed or uncompressed data. You can create a DDS file in a uncompressed RGB/RGBA (8:8:8:8) format. It can also contain MipMaps.
When the AVEVA™ XR engine loads a DDS file, it assumes that the file is definitive and loads it directly into memory, without further processing. There is no format conversion, no rescale, no MipMap generation.

BC7 DDS Comparisons
Previously, certain textures did not compress well to the BC1/BC3 formats. Now with the BC7 format, this is not a problem anymore.
The BC7 format takes the same space of the BC3 format; however, the compression quality is much better.
