CatTaker Posted October 25, 2015 Share Posted October 25, 2015 (edited) Hey peaople, As i'am new here, i wanted to ask you something. I started to learn houdini polygonal modeling and i've encountered problem with the PolyBevel tool. For no reason my bevel becames black in some point of modeling and after that i cant really do anything to fix that. I tryed everything i could think about to fix that and got nothing so maybe you have some ideas what can be the problem? I want to noticed that, in houdini 14 this problem does not show up, but only in Houdini 15. Any reasons why and how to fix that? Thanks Edited October 25, 2015 by CatTaker Quote Link to comment Share on other sites More sharing options...
symek Posted October 25, 2015 Share Posted October 25, 2015 Hard to tell without a hip file, but checkout if this is not a normals problem. Append NormalSOP at the end and see whether it helps. This shouldn't happen I suppose, you might want to submit a bug. Cześć! skk. Quote Link to comment Share on other sites More sharing options...
CatTaker Posted October 25, 2015 Author Share Posted October 25, 2015 Well, first of all thanks for the tip, it actually helped solve the problem, but still its quite annyoing to do that because it does make modeling a little bit harder. Anyway here is the .hip file so maybe you will figure it out or if it just on my computer that this happens bevel problem.hip Quote Link to comment Share on other sites More sharing options...
Jason Posted October 25, 2015 Share Posted October 25, 2015 I believe Side Effects are close to releasing an entirely new PolyBevel SOP, so you may want to hang on! Quote Link to comment Share on other sites More sharing options...
CatTaker Posted October 25, 2015 Author Share Posted October 25, 2015 Thats great, can't wait to see what they have done I'm used to maya edge split tool and smooth workflow but i find beveling more cleaner Quote Link to comment Share on other sites More sharing options...
f1480187 Posted October 26, 2015 Share Posted October 26, 2015 (edited) It happens when you have vertex normal attribute. It should interpolate, of course, but currently newly created vertices get default attribute value, which is {0, 0, 0}. You need to manually compute normals. If you don't want to break existing ones, group the whole geometry before beveling, and new faces will be outside that group. Hand-modeling in Houdini is nearly impossible now due to lack of set of well-polished working tools. I'm very glad to hear that Bevel tool may be fixed, I don't think that it will finally implement that set. However, Alexey Vanzhula's WIP modeler maybe will. The news is really, really great. Procedural modeling techniques also need quality bevel. Edited October 26, 2015 by f1480187 Quote Link to comment Share on other sites More sharing options...
CatTaker Posted October 26, 2015 Author Share Posted October 26, 2015 Anyway, its a little odd question but do you think its worth to do polygonal modeling in houdini? I can use maya with no problem but im wondering if houdini will be a little bit like a brick wall in case of polygonal modeling. I know the Houdini power is procedural modeling but for now i want to focus on one thing and than start to think about more advanced techniques. For now im creating simple geometry like tables, columns, chairs etc. so its not that bad but i wonder how does this look like where models are more complicated.

3__ Posted October 28, 2015 Share Posted October 28, 2015 ...I know the Houdini power is procedural modeling... Actually it isn't. Point/prim/edge numbers are volatile, most SOPs that create geometry won't group the newly created output, extrudes and bevels won't deal with UVs, Sops that create primitives do-so with near degenerate faces, procedurally selecting loops is a pain, procedually splitting and knitting is very difficult, many SOP operations require manual cleanup... list goes on. For destructive modeling in the viewport SOPs are pretty good however, once your muscle-memory sets-in. Definitely lacks many of the comfort features of other programs though... its just hasn't received enough attention from top modelers, who avoid it because its been neglected...

Guest mantragora Posted October 28, 2015 Share Posted October 28, 2015 (edited) Check those tools and tell me what you think: vimeo.com/139664515 vimeo.com/139546585 vimeo.com/119288387 vimeo.com/132057716 vimeo.com/139544897 vimeo.com/119965124 vimeo.com/136122536 vimeo.com/118613104 and tell me what you think about them + tell me what other tools you would like to see created.I'm re-recording those videos right now, because I changed style a little + I have new microphone which records a lot better sound + they don't show the latest versions of those tools. From those links only first two are the most current.I have one more tool in the works, which is a ripoff of Modo script called Edge Extend Magnetic ... Dissolve, which actualy can make geometry even more broken... Man, don't even start me on DissolveSOP. This shit gets on my nerves soooo much...I'm working on my own DissolveSOP, because I need this functionality for my tools, working 100% of the time.Another one is ResampleSOP. I wanted to use it in StraightenSOP to make uniform point distribution, but it was messing with one of the attributes, so in the end I made my own Uniform Distribution in VEX. TO ADMINS 1:Why not all video links generate video preview? Is there a video tag that we can use to force preview?TO ADMINS 2:Media tag half works. It added couple previews but still ignored other. And when I made all links as media tag, it also showed only first two video previews. So right now I can have 2 previews from clean HTML link and 2 from media tag. FIX IT!

pezetko Posted October 28, 2015 Share Posted October 28, 2015 Interesting tools. One thing that confuses me a lot is term of Power you are using for the parameter that affects amount of the influence. When you say power, I have connected it with exponent. For that parabola hda video my first thought, before listening the audio, was that power should be 2... I think better name for that Power parameter would be something like Weight (of the effect), or Scale, maybe even Bias could be used.

Guest mantragora Posted October 29, 2015 Share Posted October 29, 2015 I think better name for that Power parameter would be something like Weight (of the effect), or Scale, maybe even Bias could be used. But I'm using it only when I'm talking, right? Because I do't see it anywhere on the interface of this tool, beside Bend Power, and I suppose you think about Influence when Styling Scale Attribute?

pezetko Posted October 29, 2015 Share Posted October 29, 2015 I was speaking about (almost) all of your tools presented here more generally, not just that single one. See attached images please. I meant that you are using term Power where I would expect words like Weight, Scale, Bias, Influence, Strength (Bend Strength, or just simply Bend in this case), . But this is just my personal preference and connection of this ""Power" term to math terminology rather then to the amount of the effect these tools produces. (But I like that consistency between your tools). Looking forward to the Nodeway training when it will go more public Cheers Quote Link to comment Share on other sites More sharing options...

(But I like that consistency between your tools). That's the idea. To keep it as consistent between tools as I can. To avoid user confusion and make them feel right at home even if the tool is doing something different than the other one. For example CTRL modifier key is always used to turn on some control behavior. For nodes that modify geometry this will mean visualization options turned ON, once pressed, and for nodes that create geometry, since they don't need to visualize the change, this will mean grouping turned ON, because you want to have control over new created geometry. Looking forward to the Nodeway training when it will go more public Yeah, some time in the future, once I fix everything that Halfdan broke in Houdini Edited October 30, 2015 by fântastîque Mântragorîè Quote Link to comment Share on other sites More sharing options...
f1480187 Posted November 1, 2015 Share Posted November 1, 2015 procedurally selecting loops is a pain Just procedurally selected a loop without a pain using this new function: docs:/hom/hou/Geometry#edgeLoop There is also primitive and point versions. Added in 14.5.155, according to Houdini Journal. Quote Link to comment Share on other sites More sharing options...
zarti Posted November 18, 2015 Share Posted November 18, 2015 Personal opinion with small restraints on expressing it. .. there are already many types of solvers inside Houdini . adding a Bevel Solver , wd be easy imho .cheers Quote Link to comment Share on other sites More sharing options...
