i know how to paint straight lines using brush, but i need to paint a curved line.
and if possible, make the curve adjustable like the 3d path tool, but just painting color, so that i can control the curves.
any ideas?
You can choose to change your stroke type to Curve and then you can ctrl lmb click the control points where you wan them and drag to curve them. You can adjust the handles, and you can extend the curve by selecting the last control points and continuing to ctrl click. Once finished, you press Enter to stroke the curve path, and you can repeat if necessary. Since it works from view perspective, try not to move the screen unless that is intentional.
