    Big and Slow?

    When I save an A3 sized AR file, it costs me more than 110MB, even it has only one layer painted with ink pen (no paint thickness).
    When I use the transform tool in A3 size, it works really slow as well.
    ----------
    Question: Is there a way to make AR run faster and save file with less HD space?
    ----------
    I wonder if deleting some useless brush presets/filters will do the job. Maybe increase the canvas texture scale will give it less calculation. Maybe make undo steps less as well (could I?)

    thank you for your help.

    Hi there. ArtRage presets aren't saved with files, so removing resources won't make the file smaller. So, your resulting file is a 110 MB PTG when you save a single layer painting, is that correct? Could you let us know what dimensions of painting you're working with?

    It's correct.
    The canvas is 3508*4961 px.
    Exporting as jpeg gives me a 10MB picture and PNG 30MB. Well that's quite reasonable compared to a 110MB PTG. I don't really mind 110MB but just want to know how it works...
    I know when photoshop saving something it doubles its size (preview file for both pc and mac or something like that). Maybe ArtRage is doing the same. Oh I am just guessing.

    Thanks for the info regarding the dimensions and comparison. ArtRage files contain information for canvas bump, media and canvas reflectivity, media thickness, media wetness and so on, so take up more space than a standard image format which will generally only be dealing with color.

    So, when you save a PTG file, while we use compression in our files, you're seeing the result of these extra sets of information being saved in addition to just the color information.

    If you're not interested in having the additional data, you could certainly use PNG or PSD images. The downside with this is that when you then open one of these files in ArtRage, there's no paint thickness, wetness, canvas texture etc data, so while it will look the same on import, the media won't smear or interact in a way that relates to the type of media it is and its properties. So all that color data would appear as a flat layer of paint in ArtRage.

    Thank you so much, now I understand it!
