Problem coloring spaces

[Philippe GARCIA-ORTUNO]

Hello, I have a problem coloring spaces. For example if I make a circle and I cut this circle in two with a line, I can color one part in red and the other in blue. So far no problem. But when I save my work and open the session again, if for example I add a line that intersects the circle again, I can't color surfaces, it's like the new line is foreign to the drawing.. can you help me please?

If you select all of the lines, right click and choose to group them, you should find colouring will work, provided that the lines cross overlap.

Thank you for your answer, I followed your advice but it still does not work: here is a link to a small video capture of my screen so that you can see the problem. What do you think ? would that be a bug?

HI,

I can replicate your results IF I group the outer shape.

I'll guess your shape has a line at the bottom off screen that connects the left and right sides.

This to allow the shape to fill (with vectors) as it would not otherwise fill (unlike raster and toonz raster which would use the border of the canvas as a fill line).

By making the shape a different group than the line that crosses over it we break a core rule of color fill in that fills work within the same group.

There are a number of things you can do to get the fill to stop at the line:  ungroup everything, use the Simply Vectors option to simplify and segmentie the vector lines, group all the lines together, etc.

There is a bug report opened on a similar but slightly unrelated issue:  https://github.com/opentoonz/opentoonz/issues/3180

The general rule of thumb however is to keep things that need to be filled with color as part of the same group.

Here's some more information about how 'layering' of groups work in Opentoonz:

A little late, thank you very much for your help! indeed ungrouping works perfectly :)
