can we do a double brush system (2 or 3 brushes together) for example "when we draw a line or curved line can we add a totally different brush like we draw the trunk of a plant and the random leaf brush added to it. With such huge brush system and scripting ability may be we can implement it.
The old vector drawing program Livebrush (https://www.facebook.com/Livebrush/) have it.
Another suggestion is node based brush system. Something like Blackink(http://www.bleank.com/BlackInk-a115.html)
Sorry for my mistakes. English is not my native language.

See https://docs.krita.org/en/reference_man ... brush.html for a dual brush implementation. A node based brush engine isn't going to happen unless someone really goes crazy and implements it. I have my grave doubts about its usefulness. Anyway, keep in mind that Krita is open source: if you want something, consider creating it.

Oh man are you sitting in front of computer always. The answer was that quick. Thanks a lot.
But i dont agree with you. It will be there soon. we have enough people who is crazy about this program.

one more small question. Can we stroke vector path with current pixel brush like gimp and photoshop

No. It's been something some people have wanted to work on for ages, but nobody has actually written the code.

Actually, stroking a vector path is possible, make the paths, then select them with the shape selection tool(arrow), and go to edit->stroke selected shapes.

You can also stroke selections in a similar manner: https://docs.krita.org/en/reference_man ... ction.html

Thanks a lot. Actually it is a very useful option and a lot of possibilities.
