Projection painting with eraser

I am trying to erase a layer so I can see through to the layer beneath. Can I use projection painting or not. It doesn't seem to work.

all the best

Richard

P.S. BodyPaint feels really tired to me.

That is impossible.
Projection painting holds the current strokes in a temporary layer (PP layer).
When you accept move the view, or Apply the projection this is "baked" down to the layer you selected before starting projection painting.
This also clears the current PP layer.

Now if you have already applied the projection (baked down to a lower layer)
Then you no longer have paint data on the PP layer.
This layer is like any other layer, and if you try to erase something that doesn't exist on the layer, nothing happens.

What you need to do is use masks to reveal the underlying texture...that way the "eraser" is just a black and white image.

Thanks makes sense

No problem, as I was totally in your situation at one point.
Patrick: "Why won't you $%#@ing erase?! you @$#%$ing, #$@!!?!"
Screen: "..."
Patrick: "@$#$%@"
Screen: "..."

And then once I understood what was going on it made sense. (That isn't to say I don't still find myself grabbing for the eraser every once in awhile. Old habits die hard I suppose. )
It would be cool if there was a way around this to keep things a little more natural feeling...but I can't really think of anything better :/

Pat's explanation is right, but his was too technical and lacking metaphor.

See it's best to think of is a plate of glass. When you turn on projection paint you put a pane of glass in front of your object. you then paint on that glass so what your currently painting can be erased just fine, but when you want to erase on the actual object that damn plate of glass is in the way.
