OpenToonz 1.6 Temporarily Not Responding After Save and Brush tool

Ask a question related to OpenToonz

Opentoonz has worked very well for me, I had been designing a character and put in a lot of color to him. Eventually when using the Brush Tool for Coloring, when I let go of the mouse is when it's "Not Responding" for a long temporary amount of time. Same as when I "Save All" and other features beside the Fill and Select Tool. Interestingly, when I create a new blank project or I go to my older files and use the same tools, it operates normally.

Are you using vector levels, by chance?

Vector strokes create a lot of data points (control points/anchor points) which can lead to excessive lagginess when there are too many for your system to process. The brush should never be used to "color in" on a vector level. Instead, create a closed shape and fill in the color with the fill tool.

Thank you for responding!

Yes, I have been purely using Vector the whole time. I didn't use raster at all. So you are saying that for drawing things out is normally for Vector, and for coloring would normally be used for Raster?

[artisteacher]

You can draw on either. It's just that if you want to "color in" a fill area with the brush, that should be done with a raster format. Vectors should be filled in with the fill tool for a solid area.

Thank you so much for the great advice!
