Missing the texture paint mode stencil mask overlay when in texture paint mode for an object (blender 2.8) In the tutorial series I'm watching the object the person is painting changes to "texture paint mode" where the object is flat shaded like this:



However when I enter this mode my shading doesn't change, and instead looks like this:



Which makes it hard to see which object I am currently painting. My texture paint opacity is at 100% and sliding it doesn't seem to make any difference in the scene like it did in the tutorial.





EDIT I decided to try and get it to work with a new file and it doesn't. I took the default cube and added a black texture. The object still shows in 3D and not flat, and the texture opacity slider does nothing. I can't replicate what the person had in the video.

Here is the new file with just the cube: 


And a screenshot of what it looks like for me in texture paint mode:
You didn't pack the image. Anyway, I've created a new one. What you need is just to choose a brush with a higher Strength and another Blend mode. Also, be careful with your unwrapping, some faces are overlapping so when you paint on a part it will paint somewhere else. The easiest way, if you only paint in the 3D View, is to unwrap with Smart UV Project. If you also paint in the Image Editor, maybe mark seam and then choose the simple Unwrap mode.
