importing adding texture and rendering an obj from other cad program into Daz

hi, im just starting out with Daz 3d,
I'm importing an obj into daz that i modeled in other cad program, does it need to be uv mapped to put colors and textures on? i couldn't find any youtube videos to help with this ,
can anyone give me a link or a description as to how to add texture and color to imported objs
thanks

Applying textures requirs UV mapping (or a projection shader, such as Shades of Life for 3Delight). Solid colours don't require UV mapping.
