Painting issue

[MEMPER]

Im experiencing a problem with one of my brushes. Its a custom variant from the oils category, the round camelhair to be exact. In the brush creator it paints fine but when Im in my canvas it leaves white. Let me explain.
Say I have a head that is gray. Then on a separate layer I paint red atop the gray layer. The red has a whitish streak at the beginning and at the end of the stroke. Ive messed with the resat and the bleed to no avail. It also paints only whitish when I pull a stroke very lightly-however color is selected in the picker.
Anyone know whats going on?

Post a screenshot it's easier to spot the problem.

My guess is that your brush has opacity set to pen pressure and that you don't have 'pick up underlying colour' selected in the layer palette. That's why you have white at the end and beginning of your brush strokes. Though if this isn't what you mean then take a screen shot of your own.

I have the same problem, perhaps that is the answer.. would this solution also apply to painter sampling whites or any colour surrounding the object I'm colouring while 'preserve transparency' is selected?

Thanks for the screenshot Vato Loco!

Thanks for the screen shot Vato. Thats exactly whats happening. I guess what I dont understand is why it doesnt "show" the underlying color when my brush has a lower opacity (like in PS). Perhaps its just a Painter function-seeing that real paint doesn't operate the way painting is presented in PS. Hope that makes sense.
Correct me if I am wrong..with real paint, a lighter opacity/stroke/load the underlying color showing through is not really showing through, it is actually picking up the underlying color and slightly blending it together.

I've just tried that brush under Painter 9.5 and I get the same problem as you've described. Trying to fix it now... increasing the feature sorta "fixed" it.

In Painter 6.1 there doesn't seem to be any issue?

If the brush variant has blending and smearing characteristics, brush strokes painted on transparent areas of a Layer will have white around the edges.

One simple way to fix that is to open the Brush Controls palettes (Window > Brush Controls > Show General will open all Brush Controls palettes in a docked group). Then go to the Well palette and move the Resaturation slider to 100% and the Bleed slider to 0%. Now the brush variant can't be used to blend but you won't see white edges around brush strokes painted on transparent areas of a Layer.

You can then go to the General palette and adjust Opacity as needed and the brush strokes still won't show white around the edges.

@turtlehead: What 'pickup underlying colour' really does is it picks up the underlying colour of the layer directly under the one you're working on. So if you're one layer above a gray background it'll pick that color up. With preserve transparency checked it'll limit you to only working on a stroke or colour already laid down. However, if you add onto that the 'pick up underlying colour' at the edges it'll start picking up the background color again.

@memper: Yeah, it's basically the different brush engine that makes the color react the way it does in painter. The 'pickup underlying colour' box needs to be checked or else it won't ID any bg colour.
