Texture paint not working on sculpt Blender 2.8 So I have followed many tutorials on how to paint textures and it does work in simple objects, but not on a this sculpt. I can paint vertices and weight but not texture. I have tried to change to edit mode and back like suggested here: https://blenderartists.org/t/not-again-cannot-texture-paint-in-3d-viewport/532884 , no luck.


I can't paint in 3D or UV  
I see the cursor I see my texture in the same color 
it is connected to the model 
I can flood fill and change
the color of everything (again proving that the texture is linked)
Mask is not activated
my normals are correct (I can not paint inside or outside)


but the brush does nothing.

/edit: here is the file as requested
There might be a new way to paint in 2.8 but for the moment your object doesn't have any material, so create a basic node chain like Image Texture (with your "main Okulossos Paint" image loaded) > Base Color input of a Principled BSDF > Material Output.

Now you still won't be able to paint, it's because you've opened a completely black texture for your brush, so close it and you'll have access to the normal color palet:
