Description of error
Having been following a tutorial on YouTube by CG BOOST, I had successfully modelled an apple, knife, bowl and created a cloth sim.
However, once I came to texture paint the 'UV Sphere' apple, I discovered I was unable to texture paint this particular object - despite successfully having no problems texture painting the knife (modelled from a Cube)
Exact steps for others to reproduce the error
