Substance Painter - general (noob) questions

WindchILL

I just discovered this software and decided to give the trial version a try. Right off the bat it seems I'm doing something wrong.

I tried using a sample project that came with the software and i wanted to test material painting, and this is what i got:


Whats the reason for artifacts coming up like this and how do I avoid them?

When I tried uploading a simple obj and painting on that, I got this:


This model had overlapping UV's to save space, does Substance Painter not support overlapping uv's for game assets? Also, is there a setting for backface culling?

I answerer elsewhere because you posted multiple times, so here is is a copy of my message to be sure :

Those looks like bugs to me.

What is your hardware and software configuration (GPU, Operating system, and so on) ?
Are the drivers for your GPU up to date ?

For your mesh with overlapping UVs, Painter can't paint outside the 0-1 are of the UV coordinates.

The backface culling setting is available in the settings of the brush (tool window) in the advanced mode.
