Zbrush blob issues

Below is an image of the problem. When I use the brush to make a line, or raise an "area", it gets these pressure & height variations in it.

1) top detail level, smoothed at top detail level.
2) top detail level, smoothed at lower level.
3) lower detail level, smoothed at top detail level.

The red line drawn at the top ride of the small image shows the problem with height variation in a single stroke.

Now is it just a matter of refining the technique, turning off the pressure sensitivity of the stylus, or am I missing some hidden setting/tool ?

I see models like this with no height variation in a single "section", and I wonder how they get this effect. anyone have a clue?

    You might wanna try upping the "Mouse Avg" setting in the Stroke menu. I usually use 2 or 3 (although 3+ will probably give slowdown on dense meshes).
    That should stop some of the blobbiness.
    Another solution is to turn down the Z Intensity of your brush, and paint slower strokes.

    Usually to avoid blobbiness too, it's best to finalise your mesh as much as possible at the lowest possible detail level, then go up a level and add more detail ... usually more blobby models are the result of trying to go to a higher subdivision level too early in the process.

    To get results like in that image, it's just a matter of doing what I said above... spending time at the lower levels and making good use of the smooth brush.

    the stroke with the bumps, (the mounds look fairly normal?)) was that done at high subdivision? sometimes if my comp cant handle the detail it skips on samples and basically ends up joining the dots between where it recieves the input data. if its not that, you could maybe try different sensitivity modes on your tablet and see if that changes the results?

    about the model there though, I may be the worst person to answer this q but I never make one single stroke that is perfect and ends up in the final model. it all takes a lot of refining and smoothing as far as my experience goes

    edit: and I say to anyone who hasnt tried cranking up the subdivisions and doing the whole thing backwards.. give it a go its fun tongue.gif

    Yeah MoP's dead on... try working lower levels first and move up only when you need the detail. I usually work with the mouse average at 4-5 and just make slower brushstrokes. Hiding the stuff you're not working on helps the computer keep up faster as well(=less lumpiness)...also if you're looking for even height on the strokes give the layer brush a shot;)

    Yea, I work with the mouse average set to 4-5 also. I guess it is just a time thing then. I thought I was missing some key function.

    Also, be sure to go into your Wacom Tablet Properties menu, double click the tablet icon at the top, then pick "Recognition Data" this increases the hardware polling of the pen position. It's like increasing the stroke number in zbrush, only it is a hardware acceleration and doesn't slow you down as much as increasing the stroke in Zbrush does.
