mohsin_95 Posted May 12, 2003 Share Posted May 12, 2003 Hi all I am working on a new project at office. While working with boolen i have a problem. its not giving the desired results. When i do boolean more than two times on a single object, its start missing the interlinking faces. How, i don't know. Any one who knows how to fix this? Thanks Link to comment Share on other sites More sharing options...
Craig Ramsay Posted May 12, 2003 Share Posted May 12, 2003 Probably better to post this problem under your specific software... I take it that you are using max or viz? Max and viz really do have poor booleans so you are best to try and avoid using them at all costs. The example that you have shown could have easily been made from extruded splines for example. If you really have to use booleans then take a look at the Power Booleans plugin, it works much better than max's booleans. Craig Link to comment Share on other sites More sharing options...
STRAT Posted May 12, 2003 Share Posted May 12, 2003 what exactly are you trying to boolean? that colourful image doesn't say anything and that sheet of black circles i dont understand. Link to comment Share on other sites More sharing options...

Looks like he is trying to subtract the black cylinders from that green object, and the ones marked in red didn't subtact. However I have no idea what its got to do with the upper image, which looks nice nevertheless. Craig, if I remeber correctly, mohsin is a MAX user, so you advice gets another vote here.

quizzy Posted May 12, 2003 Share Posted May 12, 2003 what you could is the folowing: Make the green obeject a little denser (more polygons) and attach all the cylinders and then boolean. but the simpliest way to do this is top draw a rectangle, draw circle splines and attach them aal, and extrude'm Link to comment Share on other sites More sharing options...
Craig Ramsay Posted May 12, 2003 Share Posted May 12, 2003 Strat if you look at the circles that have been marked with green they have an inner edge where as the booleans that didn't work correctly are missing the inner edge. It would be easier to see if the object was thicker. Craig Link to comment Share on other sites More sharing options...
STRAT Posted May 12, 2003 Share Posted May 12, 2003 yeah, i see it now. max/viz booleans aren't really that crap, you just need to know how to use them effectively/correctly. insert a load more faces into that green flat bit, and also make object editable between each boolean.

Craig Ramsay Posted May 12, 2003 Share Posted May 12, 2003 Yeah I wouldn't say they are crap but beginners tend to find it difficult to get a grasp of. They work better if you are cutting into a dense mesh then you can use the optimise modifier to reduce the amount of faces in the object. I found a tutorial on max booleans once... I will try and find it and post a link. Craig Link to comment Share on other sites More sharing options...
plastic Posted May 12, 2003 Share Posted May 12, 2003 boolean operation like this one (holes in a curved surface) don't work well with mesh objects. max's booleans also are can't handle multiple operators very good (lots of holes). the best way would be to do it with solids/nurbs. with autocad or rhino. or even archicad, in case of windows. there are plugins for max for better booleans, power solids and power booleans, but i don't recommend them, since they are expensive and buggy.

Craig Ramsay Posted May 12, 2003 Share Posted May 12, 2003 Plastic have you had problems with power booleans? I have it installed and think it is fantastic, I hardly ever have problems with it :???: Craig Link to comment Share on other sites More sharing options...
plastic Posted May 12, 2003 Share Posted May 12, 2003 i tried the version 1.x demo some time ago and had some sporadic crashes when rendering. not many, but every crash is one too much. especially when net rendering, crashes are mega-annoying and time consuming. i also found that there isn't a great difference to max booleans, since its mesh based too. power soldids is a great concept, but it behaves very strangely sometimes. there are bugs that are still not fixed, 6 months after i reported them. like edge filleting doesn't work with international units (or non-english max versions). lots of quirks, non working options, crashes... it feels like an alpha version of a plugin. and a power solids object is a closed system. you can't convert it to nurbs or mesh. i am afraid of such situations. like what am i supposed to do if i want to open an old project in a few years, with max 7.0. npowersoftware may be gone, my geometry is lost, i am fucked. i rather use rhino or autocad with industry standard file formats.

Craig Ramsay Posted May 12, 2003 Share Posted May 12, 2003 Hmm good to know I don't use power solids as I have rhino but I never seem to get crashes with PB, seems quite stable to me. Craig Link to comment Share on other sites More sharing options...
Hiroshi Posted May 13, 2003 Share Posted May 13, 2003 I sometimes experience the same probs... I just group all of the multiple objects together and then hilight the object getting the subtraction and subtract the entire group. If I mess up, I use the undo function of the stack and just start over. I agree, max does have a terrible boolean system. Link to comment Share on other sites More sharing options...
mohsin_95 Posted May 14, 2003 Author Share Posted May 14, 2003 Hi all, Thanks to all, Anyways i did finish my job. But boolean problem is still there. I use Opacity map insted to get the holes screen. and here is the final shot. Critics are welcome. Mohsin Link to comment Share on other sites More sharing options...
andymcnair Posted May 14, 2003 Share Posted May 14, 2003 Hi Mohsin, The opacity map was a good idea, although i would watch the UVW stretching on the right hand side of the image. There's also some strange illumination on the lower wall - as though there wasnt a floor to stop the light penetrating through. The clerestorey glazing at this level has an ominous green glow about it. If a window were in shadow like this then you would be able to see though into the room. Might be nice to see some reflections in the entrance door screen and see through into what is presumably a reception area. Link to comment Share on other sites More sharing options...
Sawyer Posted May 14, 2003 Share Posted May 14, 2003 Yeah I gotta agree with andy about those shadows. Looks like the pop-out curved walls are just floating. Also the palm trees poking out above the pop-outs seem a bit weird. It reads like there should be a roof top terrace/garden up there but instead there are tree tops sticking up. the opecity map works great there as you should be saving tons of faces. Also there need to be some lighting picking up the shadows on the dark sides of the curves. What are you using for lighting? Link to comment Share on other sites More sharing options...
STRAT Posted May 15, 2003 Share Posted May 15, 2003 quick general boolean tut i found from a m8. bit old, but may still be of use - http://www.mousevomit.com/v1/misc/tutorials/booleans/booleans.html Link to comment Share on other sites More sharing options...
