I just received a 3D model including one obj and two tga files that are generated in 3dx Max.

When I import the obj file into Blender, obviously I cannot see the texture details provided by tga files.

The obj file contains a line referring to an mtl file with the same name which does not exist.

How can I convert texture information of tga files such that I can import and see them in blender?

I've read somewhere that I should convert tga file into png or jpg format.

Then what?
