Can the paint bucket's color range be used in different<Col>

[chainmask]

Ask a question related to OpenToonz

I have col1 and col2, and col1 is a Line draft.
I would like to use the paint bucket in col2.

Can the color range be selected from col1?
Is it possible for me to separate Line draft from color?

Tahoma2D can fill on other layers, but I don't think that's been ported over to OT yet. Of course on Toonz raster levels, it might not be needed since they are color mapped and keep track of strokes vs. fills.

Although you can't currently fill in one column when the lines are in a different column, but it's really worth considering if you really need to do this. It's often easier, for animation to have the lines & fills in the same drawing.

Thank you for your reply，
Please add this feature, I believe it will be useful in multiple software animation production processes.

There are three ways to do this, two involve deleting ink lines:

First is duplicating your linework into a new column, then filling it with the paintbucket, and then deleting the ink line with
Xsheet->delete lines, then choosing the palette index of the line.
Now you have one column with linework, and a second with paint.

Second way is using matchlines.
Here is a short tutorial on that.

It is a bit like a normal merge, but has the advantage that the lines are clearly marked as match lines, giving you more control over them (for deleting the lines for example)

And a third way is opened up if you're using toonz raster levels.
Then you can just keep both linework and paintwork on the same column, and if you need to use the FX system, you can just filter the components with:
add fx-> toonz level-> palette filter, and choose the indices there

Here is the documentation
https://opentoonz.readthedocs.io/en/latest/applying_special_fx.html#palette-filter-1

If you are not using FX though (I wouldn't know) then keeping colors separate isn't really that useful anyway, especially not for toonz raster levels and the vectors since colors get adjusted in the drawing if you change the color in the palette the drawing uses.

Moving this to Opentoonz docs although my guess is that it is an ongoing question.
