MTL File ?

ZBrush Artworks
#1

When I export An object ,it creates two files .
one is an Obj file the other is an MTL.
What does the MTL file do?

#2

The *.mtl file is the file containing texture map information for the object.

#3

So if I want to send a someone a model but not a picture (AKA texure).
I don`t need to include the MTL file ,and they could still open the object file, if the object file is all I sent them right?

I think it depends on what program you’re loading it into. I think some programs insist on a .mtl file being present along with the .obj file while some don’t.

Hi :slight_smile:
By default, OBJ export includes the following three files…

  1. The filename.obj file which contains the actual mesh data and UV coordinates.
  2. The filename.bmp file which is the texture bitmap.
  3. The filename.mtl which contains the texture file name.

If you are simply interested in emailing the 3D mesh data without texture, you should turn off the ”Txr” option in ZBrush export submenu. This will instruct ZBrush to write only one file ( the .obj file ) and the file will be smaller in size because it will not contain UV coordinates.

To make a long story short… Simply turn off the “Txr” option before you export the mesh :slight_smile:
