How do I paint over something in the same layer in a symbol?

[#1]

I am trying to make a symbol of a rock that has a specific shape of shading. I want the original shape underneath to stay but when I use the "paint inside" brush on the rock, the shading "replaces" the region of the rock part. I just want the shading to go over the whole rock, not replace it. I tried making two layers, one for the rock and another for the shading, but "paint inside" wouldn't work then. What should I do?

You could put the shading on another layer on top inside the rock symbol. Either duplicate the drawing and delete the bit you don't want shaded and coloring the shading part as black with an alpha (25% is always good).

Or have some shading (as a black 25% alpha fill on layer 2) on a layer above the rock artwork (layer 3 bottom) and Mask that with a copy of the rock artwork on layer 1 (top).

If this isnt what you mean, some picture examples will help to advise 🙂

Thank you for this. I am trying to use the paint inside feature, that was the main reason for trying to put it on the same layer. I have a picture here of what I have, and what I want it to look like. The picture is just what I want but, I'm not sure how to keep my original rock layer. Are you saying that, I duplicate the rock that I have, paint over the duplicate, and then delete the part that isn't shaded, so that I have a shaded region in layer 2, and then a complete rock on the first layer? I wanted for me to be able to move away that shaded part, like in the picture "RockWithPieceMissing", and for the whole unshaded rock underneath to still be there, along with the shading.

it's not clear to me what you're starting with and what you're trying to end with.

I am trying to start with an unshaded rock, then put the shading on it like it has in the "RockShaded" picture, but the "RockWithPieceMissing" picture is meant to show the problem I have. The part of the rock under the shading gets "replaced" with the shading. I want it so that after I apply the shading, I could move the fill section that is "shading" away from the rock, in case I want to change it somehow, and still have a whole unshaded rock underneath.

is "shading" the same as coloring?

[#7]

I think so. I want to take a light gray rock and color a dark gray section over it.

create a new symbol (movieclip or graphic).

create two layers in the symbol's timeline 

copy your uncolored rock to both layers.

lock the lower layer 

color the upper layer 

is that symbol what you want?

[#9]

Yes, I think it is. The main thing I want is to be able to use "paint inside" to match the outline of the rock perfectly. So, to get that I guess I would use "paint inside" on the one shaded layer, then delete the unshaded part of that layer? Is that right?

[#10]

So thus, the whole unshaded rock would be on one layer, and the shading part by itself would be on the second layer. Right?

[kglad]

you put the shaded part in either layer.  as long as you lock the layer you do not want to be shaded, it won't matter.
