Multiple textures on one object?

Hi,

Is it possible to have multiple different textures on a single object by ssomehow setting which polygons/UVs each 2D texture appears on?
In other words, for example, could you set each side of a cube to have a different texture, or different sections of a sphere? Is this done in Unity or somehow done in a 3D program?
I’ve tried doing this with separate geometry (breaking the object up in 3D program) but there are problems with this for what I want to do.
How does one do this?
Is this possible in the stumpy shader editor?
Is there a limit to the number of textras you can have per object (other than perfromance-wise)?
Thanks!

It is possible, and you can have as many materials as you have faces at your mesh. But this must be done in an external app like Blender or Cinema or Max. Unity is no UV mapping software.

And use fbx for importing then. You will be in trouble with the obj format. Unity doesn`t like obj files with more than one material really.
