I've been having trouble getting the texture painting to work right.

My problem is when I paint directly on my model in the 3D view the paint stroke goes to the back of where I painted, like if I paint of his chest it shows up on his back, if I paint on his face it shows up on the back of his head.

All my painting down within the UV window shows up in the correct places, though.

I haven't been able to figure out what is causing this problem. I'm wondering if I have a setting that is off that I don't know about or if something is off with my model. I've tried exporting my model and making new scenes with the export and each one has had a problem with painting.

  • $\begingroup$ How do I ensure the normals are facing the correct way? $\endgroup$

  • $\begingroup$ Okay so, It was indeed a normal problem. My normals work backwards. $\endgroup$

  • $\begingroup$ I have to say, it was obvious in 2.7, in 2.8 it's not but I must be missing something, anyway in Edit mode you can activate a Face Orientation option in the Display Overlays options, and you can see that the mesh is completely red, so it's indeed the normals that you need to flip with a select all and shift N $\endgroup$

  • $\begingroup$ Hey, thank you so much. I had no idea how to even check what my normals looked like. $\endgroup$

It's a Normals issue, in 2.8, in Edit mode, select all and shiftN to recalculate the normals

If you have custom normals and you don't want to recalculate them- select the faces that are painting on the back and Flip the normals for them. You can find that opinion under Mesh > Normals > Flip. Turn on Face Orientation in the Viewport Overlays to see which faces need flipped. Red faces are inverted, and will paint on the back
