View Full Version : VERY NICE MODLEING METHOD/TOOL! Is there a C4D equivalent?

Okay,

I thought this was very nice. Using Maya, this guy shows how to use a 2D side image of a cartoon dog to model the entire cartoon in 3D. He uses a sphere and moves the points around- v. nice. The great thing is that as he's modeling from the side view, the points he moves (like molding clay) on that side is translated to the other side of the sphere, so there is symmetry. Do we have an equivalent? Magnet tool, perhaps? If so, how does one makes certain that there is symmetry?

Check out this FREE video tut: http://www.simplymaya.com/movie_pages/tutorial.mhtml?tut_id=87

It can be readily used in C4D with a few adjustments, I feel. I just hope/wish we had a similar tool. :bounce:

You can do the same thing with a symmetry object--you just have to split your mesh.

Thanks Adam! I thought about that as a quick equivalent, but thought maybe there was a tool in C4D that would do the same w/o the symmetry object.

I think i'm going to seriously consider this method of modeling. It's something that looks easy enough...:D

Zbrush does that, I agree that's its a great way to model.

I'm trying to get the symmetry to work so that I can use the method described above. I'm also using the magnet tool, but when I pull with the magnet tool, the points at the point of symmetry pull apart. Is there a way to PREVENT the symmetry points from pulling apart while modeling?

Check out the image below...

Thanks!

Mesh Surgery used to have a tag that would keep the points on the seam clamped at 0.
I can't imagine it would be too hard for a plugin developer to write something similar?
This should really be implemented in C4d.

As far as the type of symetry you spoke about, I think this should also be implemented, it is much more better for the workflow than the Symetry object.
Hexagon has a good implementation of this as well.

HMMMMM....sounds like a wonderful opportunity for you plugin-developing geniuses to develop a plug that will automatically place an object into symmetry and allow for the use of a magnet-like tool to "mold" the object... AND keep the points of symmetry static.

moka.studio,

Mesh Surgery "used to" have a tag??? Does it still?

Another option is just to select all the points of that mesh except the ones on the seam. Your magnet will not affect those then. Problem is that they won't be moving at all, even on the safe axis.

Yep. Personally I just try to be careful with those points and if they move a little I use the "Set Point Value" command to put them right.

You can also hide the points along the seam to keep them from moving about.

Thanks Ernest. Can't afford to get another 3D app. just for this. Anyone know if Modo is capable of this?

Keeping the symmetry points static is actually not enough. The idea would be to be able to move them but w/o separating at the seam.

Man, I wish C4D had something like this.

Fabian's free plugin, MirrorPointPosition 1.3 does this. You do have to reset the realtime symmetry for each session in the tag but it works nicely.

Richard I've watched a lot of Kurts tutorials on Simplymaya and they translate easily to Cinema. He always starts with a nurbs sphere that he then converts to polys and then sub d. He doesn't usually start them in a symmetry type object. When he's modeling in the side view he uses a rectangle selection. You can use cinema's and uncheck "only select visible" and it works exactly the same. When he works in the front view he selects the same set of points on both sides of the sphere and uses the scale tool to move them in and out. This keeps the center point at 0. The only real difference is in cinema you use either a plain poly sphere or put the sphere in a hyper nurbs to get the same effect. If your really curious download the Maya PLE and try the tutorial. It works about the same.

I apologize if I am misunderstanding you but after doing a few of these I don't think your actually missing anything in Cinema to do what he is doing.

I was going to say, It didn't seem like there was symmetry or instancing used there. It may look like that because you were only seeing some nurbs edges where you would be influencing the points. There was no symmetry and it he was acctually modeling both sides at once via rectangle selections. But then again, I only watched the first one.

But even so, if you've ever tried ZBrush's symmetry modelling there's no going back - anything else seems very clunky in comparison. Actually, I can also include Hexagon 2.1's symmetry modelling in that too, I am completely hooked now that I've had chance to use it on a recent project.

Hi.

i found this issue with the points interesting, so i went to see if i couldn't write a little xpression that fixes the x-coordinates of a selection of points at the x-coord of the symmetry object.

you can download the file HERE (http://dave.dfki.uni-sb.de/%7Edschild/tmp/fixSymPoints_Xpresso.zip)

The Xpresso has some user-data fields where u should drag your symmetry-object, the mesh-object and the point selection of the mesh.



I hope this is useful to some of you, have fun with it!

maybe the Hexagon deal is still gonig on ( 30usd). Modo cost ca. 800USD, so it seems to be no option for you.

Regarding the other point ( keeping the seam in place)
As far as Mesh Surgery, which I said 'used to' have a tag that pined the seam at 0:
Mesh Surgery only works with c48 version8, and develpment seems to have stopped - at least for all pracical reasons at the moment.
You could always try asking Per if he would release Mirror Vice ( the Tag in question).

It can be done with Xpresso. Here is a quick example that uses a selection tag of the points that should not move in one direction (in this case X). It also assumes the points are all at X=0. Simple but it does make the magnet usable the way you want.

One of the main things I like about Hexagon, (apart from the crazy low price) is its symmetry modelling. You can select a plane (say xy) and then when you model the other side updates. It's very intuitive and a joy to work with. This only works on symmetrical objects so if you create something that is assymmetrical it doesn't work. But it is great for many things when you start to model.

I just got the plugin for 9.603 and I cant get it to where I can add geometry to my object. I get "Wrong Point Count" whenever I do that. Any idea what that is or how to fix it?

2 things - 1, make sure all your centre vertices are at 0 by using the Set Point Value tool and 2, set the relevant axis on the plugin pop up. ZY if you're performing symmetry on the X plane, XY if on the Z plane. Then hit Add Tag and it should work, unless your model really isn't symmetrical.

Time ago, i have realized this simple plugin: MirrorAssistant!

This is a Tag class plugin!

try this example for best know the use of thsi little lugin:

1) Make a sphere;
2) inset tag Mirror Assistant
3) Make the sphere editable

This plugin delete automatically the half part of the object and create a mirrored part! ;)

Also it delete the poligons on the mirror axis! (like mirror vice of the mesh surgery!) !

Prevent the movement trought the mirror axis ! (my bad english! heheh)

This version work, for now, only on X axis !

If u like this i can update the plugin! ;)

Thats very cool MrBraun. When using the magnet tool, the centre points do pull apart if you pull too far in one drag, but if you pull in many smaller drags the centre points stay locked. I thought this might be a bug at first but actually I guess there may be situations where you want to pull the centre points apart?
I would definitely lock this plug to my standard UI if you also developed a Z axis symmetry :)
Thanks

I just checked out Fabians mirror tool, and its really nice.
Im gonna use it a lot from now on, so thanks for the hint!

For heavier mehes though, im gonna use the xpresso solution, cos it's faster as it only needs compare the points in the selection, instead of all the points ;-P

@MrBraun: I checked out your tag and its cool, but it seems to delete some points along the mirror axis , when i use it on meg? It's kinda like she becomes a zyclop when i use the tag on her lol.
EDIT: Just thought about it, its probably because therse some points on her which overlap to the 'other side', which get deleted then...

Is only necessary to change value that control the points near to x axis! I check it! ;)

or, click on symmetry Object and change the tollerance value! ;)

@Rich-Art: tnx !! ;)

yes and no. It is very usefull, but it gives you a little bit of a taste of what this kind of symetry can do when modelling. Try out the demo of Zbrush and you will see how far you can take this modelling concept. And again, this is a really nice feature in Hexagib as well, which works not only with moving vertices but also with adding geometry ( ectrudes etc..), displacement painting etc...
