funny you should mention that... Ziggy just solved that problem. Maybe he will elaborate. ;-)

Holy smokes, that's incredible!
How long did it take to model that?

this is why I like to collect all kinds of animation and modelling tools, because you never know when your workaround might need some obscure feature that only one bit of software can do. Cool trick that 3D coat can do with the conforming sheet. I've never seen that feature in any other software.

Regarding Ziggy's ability to create this in minutes: That's why he's a Mogul. ;-)

It soitenlee is!
Is there a way to extract the 3D mesh for one of the Muvizu dummies into a modelling tool, or do you have to create it from scratch?

Posts: 1988 		PatMarrNC put up a female character template model a little while ago on one of the forum threads (can't remember which one or where - I'm sure Pat will be kind and repost the link). It's just a basic Muvizu type character blank in OBJ format, which is pretty standard. It's a good baseline to model anything from that has to conform to the Muvizu dimensions.

Edit : Found it https://www.dropbox.com/s/w0i9cuqrv1u2ivd/woman.zip?dl=0

Hey Rocque... no need to apologize for asking questions! That's what forums are all about! And although it's true that many forums are full of people who berate others for asking what they consider to be "stupid questions" this is definitely NOT one of THOSE forums!

OBJ (Oh Bee Jay) format is an old and well-established file format for 3D models which has been around long enough that it's become one of the widely supported formats that can be used to move models from one program to another. If a 3D program supports only a handful of formats, chances are good that one of them is the OBJ format.

For that reason, when people want to make models available in a format that lots of people can open in their own favorite modelling program, OBJ is a good choice.

Posts: 359 		Thanks, Pat. I learn more than one new thing every time I use Muvizu or something related to it. If I wanted your new female character, then would I have to have a 3D modeling program to use it? Or, will it just open in Muvizu?

The quick answer is "no, we can't export a character mesh from Muvizu"

But having a model of each character that can be brought into a modelling app at the correct size makes it a lot easier to create accessories for the characters. A set of models has been wished for by many of us in the past. I set out to create a full set of OBJ models, but I got distracted by life after finishing only a few.

In my opinion the "collective cleverness" on this forum is pretty high, and I suspect that if we put our heads together we could probably think up a better way to do it than the way I'm doing it (manually).

Autodesk offers a free online service which generates a 3D model from a series of about 60 images taken all around a subject. The utility is named 123DCatch.

I tried to pan a camera around a character and save the output as PNG, but that generated more than the max number of images. So I wrote a batch file to delete the extra images so I ended up with a symmetrical sample and the right number of images.

But it failed to generate a 3D model because
1) the images were too low-res and
2) I didn't have "identifiers" built into the character's skin. Identifiers are a series of randomly placed dots or characters on the surface of an object that provide a reference so the algorithm can join the photos together at the right place

I think if somebody tries this experiment again and uses higher res output for the images and creates a skin for the character with dots, numbers, letters or other identifiers that help to sew the images together, it should be possible to GENERATE nearly perfect 3D models from these characters.

more info here: http://www.123dapp.com/catch

whoever finally figures this out will have my respect forevermore

It won't open in Muvizu. The only 3d formats that open in Muvizu are ASE and FBX.

The OBJ files are useful only in a 3D modelling program where you need to make something like a helmet that fits one of the characters... (You can fit it to the OBJ model)... or in the case of Ziggy's project, he used the model to help form the shape in the sheet.

Without having something the right size for fitting, you end up blindly making an item, importing it to Muvizu, seeing that it isn't the right size and/or orientation, going back and resizing blindly until after a bunch of tries you end up with something that works. Having a reference model saves a few steps.

Then, whatever gets created in the 3D program can be saved in the FBX or ASE format for use in Muvizu. Make sense?

there's also a model for the Fat Man character: https://www.dropbox.com/s/6iwgk5z64hjrdo8/fat%20man.zip?dl=0

more to come (but probably not until fall when the live music scene slows down )


update:
here's one for Beefy (sized for FBX) : https://www.dropbox.com/s/exq857jm5pk8m32/beefy.obj?dl=0

these are only reference models to get you in the ballpark. Certainly NOT finished models suitable for anything other than sizing other items to the same scale.

@Primaveranz If you need a similar shape made (to the operating one) I'll do it for you, just PM me the details.

The visual quality of your screenshots always look better than anything I can achieve in Muvizu.

And thanks for the Fat Man Pat

Yikes! I do not think I will be ready for anything like that in this lifetime. I will be sticking with the basics for a while, and seeing what I can do there. Thanks for sharing though.

You're both quite welcome! I was tickled to see how Ziggy used the female model, and I look forward to seeing how others might use these and the other models in the pipeline!
