I have 18 OBJs models with the total size is about 10.7 GB but when I converted it to a single UDS file the output file size is about 47GB. Why this is so heavy or large UDS file created? Remember I study the conversion process here it said don't check on "Retain primitives (textures, polygon, lines etc)". I did exactly, but even without this check the converted file is pretty large? what I am doing wrong or it is normal?
