LC based Flatten tool

As part of the Unified LC tool I’ve been working on I’ve implemented also a LC based flatten tool which has few differences with regular surface flatten, one of them is that is much faster and perform a ‘harder’ flattening 😉

    Could you try to make a flatten brush….like zbrush/sculptris,mudbox.Please try Sculptris flatten.This one is yet another hard surface clipper.Its impossible to do smooth flatenning with any actual 3dCoat flattening tools (flatten,chisel,scrape and now this one).They all have no intensity slider.We need a flatten tool that perform wells on high density meshes and that has intensity slider.We’ve been asking for this for years.Even blender Flatten has intensity slider.This is a very interesting clipping brush but again Im sorry to tell you it is not a flatten brush.What we need is something like TSsmooth mixed with a low intensity negative sfClay behaviour…but that would performs 200% faster than TSsmooth…jsut to gives you and Andrew ideas.

  2. Artman, something like invert fill ? :> Agreed though, I like the idea Raul but like artman, even with plane softness 100% and playing with sampling the flatten tool reacts differently if the mesh is high polycount or using a large radius. Try it. With a big radius flatten looks like a chisel, again “doting” effect like I said in the 3.7 updates thread.

    Yeah,wow.thanx Beat!! I jsut tried inverted surface Fill brush…and its defninitely in the right direction.TSsmooth does that but it does not perform fast/hard enough witm medium radius on high density meshes..

  4. See that’s why we need a full parameters access. The actual flatten brush is suited for some work (hard surf work from the top of my head) but the invert fill is more like a mudbox scrape, following surface curbe without eating too much the surface. If we have access to those different behaviour we can share custom brushes which have specific abilities and uses.
    Thanks in advance for that Raul 🙂

  5. Hi 🙂

    Thanks for the suggestion… I’ve tried Sculptris flatten and honestly I don’t found too much difference if any. What do you mean by intensity slider? I see no problem in adding that but I would need to first see the difference in behavior that this introduces…. And yes, since is LC based it means that on very dense meshes it will perform the smaller the radius is to the point of outperform traditional surface flatten. And the dotted appearance is something that can be worked on too 🙂

  6. Farsthary, try the fill brush with invert, this is the flatten we need, we already have “chisel”, it’s what it does in your video, of course the liveclay addition is appreciated (and will definetely be helpful) but 3dcoat currently lacks a “soft flatten”, something that smooth out surface “poles” and make the surface uniform. The invert fill is definitely the way to go for that, it is soft and make the surface less bumpy.
    Best of both world would be to be able to choose the degree of suirface penetration (how much it eats into the surface), I think that’s what Artman meant by intensity slider (correct me if I’m wrong).

  7. For the soft part you may think adjusting falloff works the same but it’s not, it could be but for that to be true the dotting needs to be fixed (cause currently the line is affected by the dots AND the fallof which make the surface even less clean)

    Farsthary I dont understand how you found hardly any difference between 3DCoat flatten and Sculptris flatten.Flatten in 3Dcoat makes very hard chops like cutting with a knife while Sculptris flatten makes a very smooth averaging like TSsmooth.The strength slider in Sculptris (intensity) allow the sculptor to gently flatten instead of violently flatten when it is needed…its pretty simple.This is why there is intensity/strength sliders for all flatten tools in all sculpting apps that have a flatten tools (mb/Zb/Blender/Sculptris/Modo).It controls the ammount of pen pressure needed to achieve maximum effect.And to see the difference it would introduce just try it…slider is at the top of screen.Try it in Blender if you like or download MB demo if you like ,it is same thing there too.

    3Dcoat’s flatten and scrape tools only substract very hard slices but in Sculptris and Mudbox for example flatten gently average so surface is evenly flattened.Its very strange that you don’t see any difference.TSsmooth works very well because it is less like a knife than the other three(flatten,scape,chisel) but it does not perform well on multimillion mesh with medium radius,when meshes is too hires and radius is medium size the brush does nothing to the surface.If you or Andrew could improve TSsmooth performance,that could be a solution.I dont know how much TSsmooth rely on adaptive tessellation but if you could make a normal SF mode brush out of it we could use 3dCoat’s multires proxy mode to get good performance.

    ps:Just a suggestion:).please guys stop testing brushes on spheres,they have so perfectly distributed normals…you need to test brushes on surfaces that have abrupt normal changes and uneven density,this way you will catch up some problems before we do.

    Ok,I just found out using reduce brush before using TSsmooth gives very nice flattening control and flexibility over any surfaces,it would be great if it could be done in one brush(but maybe it would conflict with TSsmooth behavior….I don’t know how it works.)

    But the more I use it the more i think TSsmooth is the most flexible 3DCoat flattening solution right now.With reduce brush we can finally get it to work on any surface.Thanx for making that brush:).

    suggestion:I think depth slider should be renamed to something else when using that tool,it does not control depth …it seems to control TSsmooth average sample radius,it what determine if you get hard or smooth flatenning.New users won’t understand what it does unless the slider is called something else than depth.
