(Artists check this out) On the project to make a robust mixing texturing brush engine

[David REVOY]

Hi :)
Here are my thinking about the brushes :

1) For simulating hair, custom brush mask does really well the job 
normally ; no need of a special brush engine for this IMO  ( exept if a 
tweaking as I refer in '5' can work ) ;

2) For dragon scale and textures ; dynamic layer effect such "bevel and 
emboss" make magic when painting on. I miss it a lot from my Photoshop 
old usage.

3) Of course , embedded texture in stroke ( working with brush mask ) 
are ideal. I spoke of it yesterday on IRC with N-pigeon :)

4) About mixing brush , this is what I wait to make krita equal to the 
feature I abuse of Gimp-painter , this feature is present in SAITool , 
Open Canvas, Project Dogwaffle , Painter, Artrage etc... a must have for 
painting apps ... Weirdly appear in Photoshop only at CS5

5) I would really like to get the brush engine of Lukas ( hairy and soft 
brush noise ) can thicker the noise ( limited to one pixel ) . I already 
talked about it, but it seamed really complex to replace the 1pixel 
noise by a bigger size. The 1px width is not really usefull when 
painting in HD/Printing quality, because it add more noise. ( exept for 
the fake charcoal of the arabian teapot I drew month ago ; at 100% size 
of the viewport )   SAITool looks to have the same kind of brush engine 
where the noise particles can be thicker : it result with really cool 
pastel/chalky effect for noise ; and for hairy brush really cool brush 
strokes ( they name it Oil ) . I guess this is faster to compute than 
bitmap brush mask.

I hope all of this can helps.
Happy new year
