Ok for some reason when I try to paint over something, there is a "blotch" of colour left behind.
See this example here-
Just a blackish square right...
...well if I wanted to paint over that, with say the colour from the background, it leaves behind a trace of the old colour-
It stays there no matter how many times. Ive been using the Round camalhair,
chunky oil pastel, Chalks as some of my brushes.
Is it just part of how some of the brushes behave?
Really frustrating me at the moment
I'd suggest blowing up opacity, grain and resaturation up to 100 and try to paint it over again
Those three parameters describe "covering" power of your brush, all in the different way though.
yeah with water color brush i get that a lot when using layers, but i guess thats the unique feature of painter, ugly shadows like that, that in the end looks great, not like photoshop, so perfect.
Opacity at 100 helps to cover that, sometimes using layers with the picking down color de-selected, so the resaturation dont affect
There are no such things as bad art, just tight deadlines.
