    Brush Setting for Rending / Greyscale / Speedpaintings

    I have seen lots of Artists who use Photoshop-brushes that have only their Opacity controlled by the pen pressure. It's simple but works very well for rendering and I made myself a setting in ArtRage3 that works in a similar way.

    Oilbrush:
    Pressure 15%
    Thinner 41%
    Load 100%
    Rectangular & Autoclean on.

    The canvas is set to 0% structure, a bright grey background and a nice size about 2000px.

    If you draw very lightly you will get a layering and crosshatching effect. If you use more pressure you will get pasty and solid colours and blending tones.

    Simple but effective

    I don't know a lot about tones and greyscale yet, but I guess the basic "white" skintone is about 17% black. Any real white parts in skin are caused by reflected light ...

    Thanks, that is one nice brush !

    I noticed something weird though, with light pressure,and overlapping a few times.Could this be some kind of bug in the program ?

    Yes, this happened to me, too (You can see it in one of my darker spheres). But not as clear and dark as it appears in your image. Actually I kind of liked it and on my PC it appears only if you layer up a looooot of strokes and also only slightly - but in your image it seems to pop up after 3 layers only. Thats not really handy, I guess :/ It's a bug for sure (a smearing problem perhaps?), but the intensity seems to vary - I have a quite powerful PC and used a big Canvas + big brush, and I had no "transparent" layer, but filled it manually with grey... I'll experiment with it a bit, but I just remembered: It happened from time to time, that colors with high transparency behaved strange when I smeared them...

    I don't know if it's already a known issue, but here's what I found out:
    With pressures from 1 to 3 and therefore a very high transparency you get those 100% opaque artefacts in the third Layer of strokes (doesn't seem to add more artefacts in additional layers).

    (Thinner set to 41%, Load 100%)
    It does not happen when you set the Pressure to 0 and does not happen with Pressure more than 3. Actually it seems to be strongest with 2%.

    If you paint very, very lightly with pentablet youre in the 1 to 3 pressure area quite often, it seems. I did a couple of more tests with pen and mouse. For illustration I used the mouse and a fixed pressure setting.

    Workaround:
    Try to paint not too lightly... :/ Not exactly a great solution I know. With my personal drawing style I'm very likely to produce artefacts, when the base pressure is set to 0, but when it is set to about 15% I need to slow down a lot to make artefacts. Downside is that you can't benefit from the layering effect toooooooo much because higher pressure produces less transparent strokes...

    Edit: I did another test row. With pressure fixed to 2% and increasing Thinner-values. With thinner lower than 36 and higher than 46 barely artefacts showed up - BUT there is a shift: now you get artefacts with higher pressures. With thinner to 46 there will be artefacts within pressures from 3 to 7

    Hanzz, are you working with the oil panel of AR4 ?!!
    I am no sure that the first settings work the same
    on different panel.

    I will show you my oil panel, ink pen panel
    and the brush in the oil folder (couldn't work with the ink anyway)

    How about that ?

    My bad, I had switched to the pen tool, I was intending to make annotations on the image, I then decided against it,and simply forgot to switch back to the oil brush......You'll get old one day too !

    Here's the settings as I got them from the .prs file.

    edit: It is confirmed as being a bug,and is being looked into.

    Hanzz, is OK, I may eventually be older than you , we all can have inattentions .

    I work with a bamboo tablet in this moment and the strokes that I obtain with this shading brush, at the same settings, are different than yours.

    I did a sketch with it in a speed way .
