I'm sure the same applies for other poly modeling applications but I'm using Maya. Lets have a go at a simple scenario and then look at my slightly more complicated mesh that needs attention.

Ok, you have a surface comprised of ...16 faces and 25 verts, just a plane. When the surface is created it's planar with all it's parts existing on the same plane, in harmony. Yay! You rotate the surface on all 3 axes, blah blah still planar, awesome
Now, here comes the issue. (Oh no!) Several of the verts on the surface have somehow managed to stray from their planar neighbors and are now making a surface defective, not flat.(by no fault of your own, ofc)


Whats the best way to fix this?
The only thing I've come up with is deleting all the affected surfaces, use a fill, and then shunt over the edges with the split tool. But that may not always be a solution like in my case.


I don't have four border edges that are viable for using as a reference.

I've tried using the scale tool, selecting the faces that need to be leveled accordingly and using the good face (green) as the reference,( Set To Face/Edge/Point) but that makes the (red) surfaces move a lot more than what is tolerable, because it causes bigger issues. I run into this problem a lot.
Any insight on how to avoid this, or fix it would be extremely helpful!

Thanks!]]> Sat, 11 May 2013 16:23:58 +0000 http://forums.cgsociety.org/showthread.php?t=1102861 Posted By: Darth-Biomech

What do you do when you need to cut many non-rounded holes in object? They need supporting loops, and that supporting loops need to go somewhere... This is not a problem on a flat surface (I can create as many n-gons as I want as long as they are convex, ha), but what if you need that kind of mesh on curvy surface? For instance, I'm now struggling with this piece of starship: it has many holes on it's bottom, and it must connect smoothly with spaceship's side. Any sort of advice would be really helpful.]]> Sat, 13 Apr 2013 16:39:50 +0000 http://forums.cgsociety.org/showthread.php?t=1101869 Posted By: megamanx

Hello all! Is there a tutorial that teaches us to model professionally as this helicopter. The amount of detail is absurd. It requires a special technique to do this.
I wonder how it's done this type of complex modeling. Theres some tutorial?

Hey,

first of all, i am the new here and english is not my mother tongue, so please be kind to me.
In the context of an application-test I want to design and model some vehicles with Maya (since i have free access to it).

I understand the basic tools of maya but when it comes to bigger projects like detailed vehicles I have n clue where to start.

For example, i dont know how to model very precise, make bending shapes with crisp edges and all of thise while only using quads. (So i can import my models into Mudbox,...) Also how do i approach such projects, start with simple shapes and then splitting them?

Do you know some good tutorials, optimally free, which teaches those kinds of stuff? I watched a basic tutorial for maya but they must have thought, the buyer is working with a PC for his first time. (I waited for the instruction for how to close the window^^)

Thx for your help ]]> Wed, 20 Mar 2013 11:17:08 +0000 http://forums.cgsociety.org/showthread.php?t=1098004 Posted By: tgreenfield19

Hello,

I'm new here, and could really do with some help modelling some geometry. It's an architecture project, and I am trying to work it up from a sketch and finding it really difficult. I use rhino 5 and vray for rendering.

Hello all,

my first post here....with a normal issue while polymodeling.

I extruded a cylindrical shape out of the corner of a cube and ran into irregular distrubution of faces like this:



I could replace it with a regular poly cylinder, but this would be too easy. I want to learn & understand....

Obviously the problem here is caused by the normal directions.
After remodeling that cylindrical shape with a standard cylinder (got the same look again) my question is this:

How to shade such a piece of geometry softly?



Thanks in advance.....]]> Fri, 01 Mar 2013 09:43:07 +0000 http://forums.cgsociety.org/showthread.php?t=1095395 Posted By: sturmadler

Doing work for an indie game project with a small team. The design calls for a number of low-poly hard-surface models with lattice-like structures (realistic spacecraft).

It is very tempting to use the lattice tool for this work, although the meshes it generates result in very tedious cleanup (the vertex count can be reduced by half and the poly count by as much as one-third).

Tell me someone else out there has encountered this problem and developed a script to solve it.]]> Sun, 24 Feb 2013 13:01:02 +0000 http://forums.cgsociety.org/showthread.php?t=1095140 Posted By: Pmiller

Hey everyone, after searching this place for a while, I wasnt able to find any answers to my question so I decided to ask you.

I'm modeling a bow and arrow, I'm modeling the arrow, and arrow head right now, and my technique for modeling the hard surfaces/edges, and creases is to simply drag the edges closer to another.

Here is my question. Is the way I am supposed to be modeling these hard surfaces? Is this the way I'm supposed to be modeling hard surfaces, especially if i'm going to attempt to animate the object later?

Thank you ahead of time for your help ]]> Fri, 22 Feb 2013 14:23:40 +0000 http://forums.cgsociety.org/showthread.php?t=1094777 Posted By: matt319

Hi,

Does anyone have any suggested tools or workflows for reducing architecture scenes from 400 000 polys in 20 000 objects to about 30 000 polys.


Projection unfortunately does not work, partly due to the massive amount of objects.

Ideal would be some type of retopologizing and texture baking - but naturally any ideas would be appreciated - I would expect that the same need must have been out there before - searching however has not given any relevant results.]]> Fri, 11 Jan 2013 13:56:33 +0000 http://forums.cgsociety.org/showthread.php?t=1085760 Posted By: JamesArndt

i am trying to recreate the Bionicle Voya Nui logo , the grated muzzle ring with a glass dome in the upper right corner of this image.

http://1.bp.blogspot.com/-EBYch8iojQ0/UEKM5ekZvCI/AAAAAAAAAbs/346STLT_8nQ/s1600/Christian+Faber+Files_Piraka+logo.jpg

i can make main parts out of primitives,squashed cylinder for the base and a clipped sphere for the dome , but i am having trouble with getting the holes from the grating in round base.

to get the holes all over the base i set both the sphere and the cylinder 's radial subdevides to 32 (multiplying by 6). then i take out a 3-segment wide slice and cut the holes out with a boollean difference with cylinders ect. basically get clean holes with good edge flow. then i do a mirror and weld to make it a repeatable mesh and basically repeat the process until i remake the ring.

but i think i messed up with the welding and such because the edges between the base and dome dont line up

you see the mirror and weld didnt actually work for me. for some reason instead of placing the mirrored duplicate right next to the orignal it sent it off like several distance units to the side so i always had to pull it back in and weld it manually. but they never aligned right so with each mirror and weld the segments were squeezed and made the edges skew.



so i was hoping if there was an easier way to make segments like this line up automatically. i know in zbrush they have a radial symmetry setting for the brush so maybe maya has something similar. kind of like this :



either that or any other technique that would work as well or better. i know i can just go into zbrush and drill the hole grating in with the aforementioned radial symmetry brush but i never get stuff like that aligned right and i like the crispness polygon modeling gives t these sorts of hard surface.

i will be thankful for any help and advice but if possible can i have tutorials? will be very greatfull.]]> Tue, 18 Dec 2012 03:22:02 +0000 http://forums.cgsociety.org/showthread.php?t=1079728 Posted By: Reed5point0

Morning guys, here is my obligatory "I'm not really a modeler" excuse. But I promise this will be an easy question.

I have seen a tool in Maya, that let me select a face of an object and then select a vert, edge, or face and it would snap and orient the object onto the other. For the life of me I forgot the name of said tool.

Here is a current screen grab of my issue to maybe make more since. The red arrow I added is even a rough interpretation of the display curve it gives you when using the too.



Basically trying to snap these bumpers on this roulette tables inclined surface and want to do it with ease and consistency.]]> Mon, 12 Nov 2012 10:48:33 +0000
