    Still can't reproduce... Are you brushing with pen or mouse? Does same happen with mouse? Please show me screenshot with settings.

    no special settings...really basic stuff. Crash happens when using mouse too.

    Im not surprised you can't reproduce since Im the only user who seems to experience this with 4.5.26A. Normally I would think something is wrong on my system but since I experience no crashes at all in 4.5.25 it means it the issue comes from the build itself.

    I remember one time you sent me a build that was able to "record" the issue while happening that was better than crash file report.Maybe you can send me this kind of build again...

    Maybe you remember what tool was used whan crash happened? I still can't reprodice. Is it on big default sphere? How often does it happen?

    always after approx 10seconds brushing ,using most of my Liveclay based presets (sharp ect..)

    Big sphere or headbust....Its a pity crash file does not tell you what is wrong :(.

    Anyway,maybe there is a problem on my side (windows,nvdia ect...) but crash does not happen in 4.5.25 now after 1 hour sculpting.

    I will try redownloading 4.5.26A.

    Great update, Artman! :)

     

    I have several questions about it:

     

    1. I see that you have dropped the Rapid2-based Clay preset. What might be the reason behind it?

    2. I also have noticed that amClayBuild utilizes GeneralClay. Is the brush safe to use now in 4.5.16?

    3. Finally, what is the purpose of amFix and amFixArea brushes? When do you use them?

    1.I dont use it anymore as Im always starting from 200k-300k lumps of clay and RemoveStrteching does not generate enough resolution to produce nice clean clay strokes.

    JoseConseco asked me to make a livecaly based Clay brush (amClayBuild) 

    and after making it I really started loving it a lot :)...you see,I really need those strokes to be nice as I use the natural folds and creases it creates when crossing strokes to base most of my organic wrinkles from.

    Also when using it for hardsurface I also enjoy more resolution in the strokes

    But feel free to keep using the old Rapid2 one ,anyway it was pretty close to default rapid2 anyway...but I might have fiddled with the flatten curve a bit.

     

    2.For this particular brush I dont encounter any issues on a daily basis, but I dont indulge in the build up aspect of this brush...

    somebody might use it to too much extremes and get unhealthy self-intersections, Its true of any brushes with "build up" anyway.

     

    3, AmFix purpose it to remove any sorts of bumps in hardsurfaces that are already flats, I use it in both add and ctrl mode to be sure erything is super crisp. amFixArea is basically the same brush but using curve (the way to define area is to set different radius to the curve points to cover surface as much as its possible .Then by using Apply in both add and Ctrl mode multiple times(a hotkey works best for this) I get very sharp,clean surfaces.)

     

    The purpose of both those brushes is to remove the "sculpted" look out of hardsurface sculpted parts so they can look similar to what you get when creating hardsurface using subd modeling 3D packages.I dont think poeple are gonna use them a lot,but personally I really needed those,they really were a missing piece for me.....you see ,I dont want to do any retopology for the sole purpose of sharpening  hardsurface shapes,its already a big enough chore to make the lopoly retopo for bakingI,m not gonna make an intermediary midres retopology on top of this ,that takes all the fun of sculpting it in the first place imo...

     

    The strong points of this update imo is really the polish and Trim brushes which are less harsh then the ones bundled in 3DC and are really complementary to both make sharp bevelling with Trim or really intricate hardsurface shapes with Polish.

    and the Sharp brush which imho is superior to DamStandard brush (mostly due to adaptive tessellation) I had to balance it a little bit when Andrew changed the relation between depth and radius.

    updated to the version i am currently using in 4.5.16 (file is in page 1 of this thread)..... some older bushes seems really out of place and weird, anyway they went through so many iterations that I dont know which ones people are using...so make a backup if you plan on installing those new ones there might be some older one you like better.

     

     I tried intsalling older pack and really had an horrendous experiences with some brushes like polish or HD sharp(when I tried them they only crush the mesh with crazy pinch,seems like there is no depth to them anymore...)I don't know what went wrong or maybe some things changed along the updates ...anyway,this version is the one that I use and has the best feeling for me...

    Thanks for clarifying this, Artman. I began thinking that something might be wrong with my 3DC installation.

    I'm not sure if mimicking this particular ZBrush feature benefits 3DC. It feels illogical to me, because when I turn off brush spacing, I expect a continous stroke.

     

    well there is always gonna be some sort of default spacing because brush strokes use images alphas and those have to be somehow repeated along the stroke otherwise the stroke would never have anything to do with the alpha used....it would be just a generic stroke controlled by falloff...

    The dots you see comes from the fact that the alphas used are too small.....there is too much black space versus grey/white space on the image.

     

    If you use broader alphas you will  notice no dots even if spacing is off...

    Here, no spacing using the first 2 default alphas:

    When brush spacing (Use Spacing) is turned off, why does LiveClay brushes act as if it was on? I don't see this problem with standard surface brushes.

    Is it how it is supposed to work, and if so - then why?

     

    attachicon.gifLC_useSpacing.jpg

    I wondered the same thing a long time ago and did some comparison in Zbrush to discover that its exactly the same.

    Here is DamStandard (CreaseClay equivalent) without lazystep spacing(left) and with very low lazystep spacing (right)

    post-1195-0-71533600-1439101057_thumb.jp

    As zbrush is always considered  the ultimate reference when it comes to sculpting I never went further with this point...assuming it is probably normal.Altough in 3DC its much more apparent....to such an extent that using CreaseClay without low spacing values is not even considered an option.

    Actually most of my Liveclay presets use very,very small spacing values...

    Im like you on this ,I dont know if its an issue or not....

    Also you wil notice that those dots manifest mostly when small/sharp alphas are used,if broader alphas are used you can desactivate spacing and still get nice,even strokes...

    I'll try to stay away from the latter although I like the tool very much because it's basically a Swiss army knife. It contains almost all LiveClay tools which allows for creation of very interesting brushes.

     

    Not really because the Liveclay brushes underwent massive refinements of behavior and brush feeling while General Clay did not benefit those improvements. So CreaseClay is literally lightyears ahead of generalclay+ Creasing and same for Flattenclay its been refined by Andrew many,many times and general Clay+Flattening is nowhere near....

    Creating yourself a nice set of presets and assigning hotkeys to them really gives an almost swiss army knife feeling if you want.

     

     

    Any ideas on why there is only one type of noise available in the Nose tool while most LiveClay tools have 8 different noise patterns?

    Yeah,noise tool is just Perlin based....Voronoi would be great,especially with curve control.

    Those are really 2 complementary kind of noises ...and by having both pretty much any effects can be achieved.

    I already asked for this when tool was introduced as Im pretty sure Andrew can code some Voronoi noise functions in like 30 seconds.....So who knows,maybe it'll be introduced someday. :)

    Of course, Artman. Pardon the vagueness of my post. I was going to write a longer version later, during a break.

    I'm currently sculpting some stone objects. They have noise applied to their surface (with Noise tool). I'm using Rapid2 brush with Remove Stretching to carve their edges and every now and then I get a hole or self-intersecting areas which I then have to fix (with Fill Holes or smoothing - if it's a self-intersecting surface):

    attachicon.gifrapid2_hole1.jpg

    attachicon.gifrapid2_hole2.jpg

    attachicon.gifrapid2_intersecting_surface.jpg

     

    Yesterday I was trying out some different configurations of cracks on the rocks. To make the cracks I used General Clay tool (with some noise, but it produced some intersections. So I enabled detection of Self Intersections, but like I described in one of my earlier posts, it generated holes and spikes.

     

    Finally, from time to time (well, rarely) during brushing I get small areas of dense triangle concentration that only CleanClay can fix.

    I suspect noise to be the culprit.

    Also General Clay is a pretty unsafe/experimental tool...self-detection is also pretty experimental (not tested/used by many users)

    and it also makes your brush super slow (probably why most users stay away from it)....

     

    If you can catch one brush stroke that create a hole,undo and send file to Andrew with instruction on what brush to use at a particular area to generate hole he might be able to reproduce and fix.

     

    What I recommend if you dont want to wait for a fix (which may never happen)

    -Use Noise tool.

    -Convert to voxels (yes file is gonna be heavy to capture all noise details)

    -Return to Surface mode to keep sculpting (Remove strtching is very safe)

    -Avoid General Brush and self-detection

     

    But generally "sculpting" with Remove strecthing and most Liveclay brushes (liveclay,Creaseclay ect...) is pretty solid.

    But its also easy to force self-intersection by keeping pressure on the brush intensively without releasing the brush and letting RS do its magic.

    If you intend to do this, voxel mode is better suited.

    I still keep getting plenty of holes when sculpting in surface mode with standard surface- and LiveClay tools. Is there a chance that it will be fixed eventually and once and for all?

    could you be more descriptive (show screenshots of wireframe,explain which tools are used (detail level ect..)

    I sculpt in surface mode every day(Liveclayy,RemoveStretching) and I dont remember the last time I had any sorts of holes....

    Maybe you already tried this, but re-install the latest driver, and at the beginning of the install, choose CUSTOM. After you proceed, there should be a small checkbox at the bottom left with the text "CLEAN INSTALL." That removes the old completely and installs the new. Then see if you still get that error message in 3D Coat.

    Thanx,its working again now. :)

    (But it worked fine when I installed driver the first time....then stopped working for no reason after a day or 2.)

    Lets hope its still working in a few days...

    artman, please try this version:
     
    from now programm first initialize OpenCL.dll from device vendor, if failed - program try find OpenCL64.dll from vendor, and if failed again - program automaticaly try use DLL from Khronos Group.
    One of these has to work properly.
     
    WARNING: Necessarily you need to delete OpenCL.dll and OpenCL64.dll from 3DCoat instalation folder. (Keep only cOpenCL.dll).
     
    in this update also fixed: error painting on AO layer after calculation...
     
    Thanks!

     

    now it says ; "Error 2:can't get the number of OpenCl platforms.Method 0."

    really wish i could help you more. :(

    I'll ask user Jose Conseco he has gtx 660 too.

     

    Edit: I've sent him a message...we'll see,

    AbnRanger does not seem to have any problem since he updated the driver.

    With latest driver it was working too on my side but it stopped working after a day

    ...right after I changed UI a bit...maybe it is related.
