    Painter speed problem after using impasto brushes

    Hi Jinny and all,

    Working on a MacPro 9GB of Ram and Leopard, I see a problem that seems affect both PX.I and P11:

    on a file of 4000x4000 pixel at 250dpi (but it happens on low res document) I painted with different brush categories at big size:

    Chalk (Square chalk size 183, Square chalk 35 size 353,5), Pens (Real drippy pen) and  (Wet Brush size 382,6). They works well and fast

     

    Then I choose  artist's oil- impasto oil size 322 and after I tried to paint with the square chalk used before: unusable.

    It became really slow, also at small sizes.

    I cleared impasto but nothing change and I have to close the document.

    Reopening the same image Chalks and the other brushes work fine until I used impasto oil or impasto brushes again.

    I'm going to check it with other brushes but  can someone verify this behavior?

    thanks a lot

    Paolo

    When you change your brush size have you also changed the feature and spacing settings before you tried painting with them? It sounds like the PC  (sorry, COMPUTER) is playing catch-up to brushes that are using features and spacing not needed for large sized brushes.

    You can check out John Derry's Hot Rodding your brushes. http://www.conceptart.org/forums/showthread.php?t=55589

    It would be nice if there was some kind of "auto-adjust" feature for some of these brushes where it will adjust the spacing, boost, and feature so that people who don't know about the settings maybe can get warned about performance, or it calculates some average for them with a warning.

    no, the brushes are the same, I don't change brush feature and settings. 

    I'll check out your suggestion. 

    Thank you

    Oh dear yes! I followed your path of doom in Painter 11 and had the same problem; the chalk brush crawls horribly.

    Impasto brushes uses 3D calculations so it will require more processing power from your system.

    Hi Paolo,

    In addtion to John Derry's thread (very good one to read), also check my Sticky thread that includes multiple suggestions that can help if you use them:

    Keeping Painter 6 Through Painter X.1 Running Smoothly - Updated February 6, 2008, by Jinny Brown

    Also, unchecking the Enhanced Brush Ghost box and Draw zoomed-out views using area-averaging box located in Preferences > General can help speed up Painter's performance.

    Hi Jinny,

    it's fun that you call me Paulo, instead of Paolo! 

    about speed problem, thanks Robyn your words are perfect!

    Jinny Brown:

    It was the first thing I did setting Painter Preferences. I know enough the problems so times ago I set them as you wrote in your suggestions

    (John Derry 's thread is really very good and clear and your too) .

    But why after an impasto brush, doesn't a simple square chalk work as usual? It looks like Painter keeps memory of the last complex brush controls and it conflicts with the new one

    Is it a problem that affects only Macs?

    Thanks a lot

    If you go to Window - Show tracker and clear all, does this problem remain? I'm just curious.

    Hi:

    I just took a look at this and was able to duplicate it.

    It appears to be related to the creation of an Impasto layer.

    You can:

    1> Open a new document.

    2> Enable Impasto (don't draw anything on the canvas).

    3> Disable Impasto (or more directly, use the "Clear Impasto" command).

    4> Draw with a large diameter brush.

    The brush is very unresponsive.

    I believe what is happening, or in this case—not happening—is that the Impasto layer data (or a flag to it) is not being removed. Combined with large diameter brushes (which require more bandwidth to render), the phantom presence of the Impasto layer cripples performance.

    You can clone the file and the formerly unresponsive brush performs as expected. This is a clear indication that some remnant of the Impasto data remains in a file even when it has been cleared or disabled.

    Pixels—It's all in how you arrange them.

    Re: Painter speed problem after using impasto brushes

    Does the same to me to.  Instead of cloning I save as .psd to keep layers, close and reopen the file.  Clearly since the photoshop file format can't save the impasto info that data is deleted and the normal brushes speed up again. 

    In .rif format, after choosing Canvas/Clear Impasto (and also toggingly off the impasto effect button) doesn't seem to 'clear' anything, because if you save then reopen the file the Impasto button is toggled 'on'....  so what has been cleared - nothing??!

    Hi Jinny,

    Hi Paolo,

    Thanks for letting me know I misspelled your name. I am aware of the correct spelling but guess my fingers forget. I used to co-moderate the Painter forum at In Depth Discussions with Paulo Roberto Purim and typed his name millions of times so now I need to make a special effort to type your name correctly.

    Please accept my apologies. I know how annoying it is to have one's name misspelled. Though mine is available to read in every post, people still spell Jinny incorrectly, as:

    • Ginny
    • Jenny
    • and several other variations.

    Yours is Paolo.

    Mine is Jinny.

     

    Cheers!

    Thank you Jinny,

    don't worried about it: It was really fun for me: I thought you mixed Paul and Paolo!

    Have a good day
