After attempting to put a .blend and .obj file into the mesh slot for quixel DDO, it rejects both with the same error as seen in the .png and topic.
In full, it's "There seems to be missing Texture Coordinates (UVs) from the mesh. Please make sure UVs are exported alongside mesh!"
The .blend file has a High Poly and Low Poly (specifically a Retopology of the High Poly), and the image is before a normal map is baked.
Please help, and thank you for anybody's time.
