I've done 3d printing before, but not in color yet. I wish. Still trying to get this first textured file right. day 17, *sigh*

I've been trying to build some wigs with voxels, then I export them, perhaps after coloring them, as .obj's. Then I open them in Accutrans to Czech their watertightness and I get "edges with 3 or more shared polygons". Any suggestions on some auto-repair kit for leaks that have sprung in my wigs?

Obviously you have a well-deserved name.

GrandmasterB-- merging meshes onto voxel object, then retopo mesh of the voxel object with textures(?) that sounds like something I'll have to attempt... then after that you say 'project the textures on it'... wouldn't I not need to project if I could retopo mesh with textures, or is that the same thing as projecting the texture? I have hundreds of these scan files on the way to convert so I need quick and preferably idiot-proof (yeah, I know, you deduced that part) workflow plan. One idea is to convert the idea to some format that recognizes texture but only one layer (is there such a thing?). Or could it be converted so that each vertex is assigned a color? AbnRanger, there's a bunch of gradient zcorp printing, see examples on sculpteo.com. here's a sample texture. It looks like there are 9 of these for the particular scan.

Question: Could anyone do the following type of task in 3D Coat? My one 3d Scan, previously referenced in other posts, is a composite of several scans. [Due to the Artec MHT 3D scanner technology output] I know this because when I open it in Accutrans it shows up as 10 meshes, each with its own texture (see image below that shows 9 of 10 meshes and 10/10 meshes). Does anyone think there is any way 3D Coat could combine these meshes and textures into one mesh/texture in 3D Coat? [Note the meshes are each complex collections of islands.]

I am on Day 9 of an attempt to simply take an .obj file from color 3d scan, extrude it and save it to be printed on a zcorp color printer (the only color printer?). I can open it and extrude it in 3D Coat or Blender. (or Rhino, but I can't see the texture in Rhino). It behaves like one surface when I open it in 3D Coat or Blender. But then if I extrude it and open it in Accutrans to makes sure it's a (required) watertight vrml file, Accutrans says it's not watertight. Accutrans thinks it's a quilt of about 8 meshes with separate textures. If I then try to tell Accutrans to merge the meshes (called layers in Accutrans) it does so but looks like the texture(s) have been through a lawn mower. I think polyxo sounds like the voice of experience and great oracle of knowledge, but, pathetically, I'm not so sure I'm capable of even implementing these guidelines, though I am trying. I did what I think may be the first 4 bullet points but I don't see the texture. --heck with adding the hair. I'd be thrilled to just import the face, extrude it, and successfully export a vrml to shapeways. --but to keep the texture(s) intact. (I have 3d coat, blender, rhino, meshlab, accutrans, but proficiency with just rhino so far.) but how? p.s. I tried to attach the scan, but altogether it's more than the 7 mb forum limit) I'd be happy to send it anywhere else.

hey polyxo, wow awesome-looking instructions I'm going to try them right now. ---so grateful, so grateful, fingers are crossed. spacepainter, am using MHT Artec scanner.

I have been trying endlessly to figure out how to do something in 3D Coat: http://3d-coat.com/forum/index.php?showtopic=8367 So just took a break from clicking around in circles and posted an ad on elance to pay someone to tell me how to do this simple task in 3D Coat. http://www.elance.com/php/bid/main/proposalConfirm.php?jobid=25249624 so what are you slackers doing driving home from work when you could be helping me for lunch and/or beer $?

I photoshopped the voxel-built, blue Medusa hair on my textured skin (from the paint room) in this image. Isn't there some way I could produce this kind of combination so that I could then paint the hair color (something other than voxel-default blue) AND touch up the skin at the same time... Then then export the while thing as a textured file hair+skin and so on for eventual printout on a zcorp printer?

hi Greg, Thanks, now I feel like I'm getting pointed in the right direction. But I think I'm missing one step maybe. As you can see in the images below (you probably don't even need to look, but..) 1.) I open 3DC, then open obj model for Per Pixel Painting. 2.) I Import Mesh for Voxeling 3.) I select "merge as skin", "respect negative volumes" is pre-selected, "transform" is pre-highlighted, then I click "Apply". As shown in screenshot 3 it looks like 2 overlapping/merged layers. 4.) I select muscle and draw on some snaky Medusa hair. ?.) But now I want to begin painting on the hair I've just created. If I click pack to the Paint tab, the Medusa hair is not there. How do I get it there? Gratefully yours,

Okay, I figured out much of this answer, so I can greatly simplify the remaining question. Say I 3d-scan the girl in the attached image. But since no hair is scanned, I want to model her a "digital wig" in the 3DC voxel room. Assuming (i hate to...) it is not possible to directly import the fully-textured scan into the voxel room, then what is the next best thing? When I build up the 3d hair in the voxel room I obviously want it to conform to the scanned-model's head size and shape. I can see and manipulate the scanned model in the paint and even sculpture room, but how can i view the form in the voxel room so that I can make hair structures to conform to it... sort of like the green modeled hair I PhotoShopped into the attached image. The following thread suggests this is a tough challenge, but how might you 3DC experts go about modeling hair to go on the hairless scanned model? http://3d-coat.com/forum/index.php?showtopic=6623

For example, while on the Paint Tab I was airbrushing on the model in the graffiti image, but then when I try to click over to the Voxels Tab, so I can create some 3d hair, the model of Tara completely disappears (but reappears when I click back into the Paint Tab). ---and of course in neither case have I been able to start with the nice photographic texture of the original 3d scan. I'd love to be able to airbrush on that. What 'm ah to do? (North Carolina accent)

Here are three images of Tara. Tara_7-16 is from a 3d scan I just did. Yo_honey.jpg is where I created hair on a hairless 3d scan of Tara with the muscle tool in 3D Coat. And finally, graffiti_Tara.jpg is where I imported a 3d scan of Tara and airbrushed on it in 3D Coat. But here's the question: Is there any way I can marry these 3 techniques in 3D Coat? I want to: 1.) Import Tara_7-16.obj (or whatever kind of file with the 3d-scan photo texture) to 3D Coat. 2.) Then build muscly hair in 3D Coat like I did in yo_honey. 3.) Then airbrush (realistic blond/brunette) colors on the hair like I did with the random colors in graffiti_Tara.jpg. But the problem is I can "import mesh for voxeling" to create the hair with the muscle tool but I don't know how to apply or preserve the surface texture of the original scan. The texture data is not imported in as far as I can tell. In fact I don't even know how to open up a 3d file in 3D Coat with the photographic surface texture of the scan. Is it possible to marry these 3 techniques on one model in 3D Coat: import model with photographic texture, create 3d hair/color hair...?

Thanks a lot you guys. That is a lot to try to start working my way through. I'm only one day into 3D Coat. After I get the form right does 3D Coat make it very easy to start airbrushing hair colors in or I wonder what the easiest way would be to apply realistic hair color?

I've made this face with brushing up voxels. But I can't deal with a solid. I want the traditional, skin-deep beauty. Is there a very easy way to simply peel/trim/undrape/whatever the surface of/off the face so that I can the extrude it to a uniform thickness? So, if doable, 1.) how do I get the surface off? 2.) how do I extrude it to a uniform thickness?

I like the muscly voxel hair creation. I have been "brushing on" hair to the sphere in the voxels "room" or screen or whatever you call it. But when I try to import a head to which I can subsequently begin applying hair I get into trouble. The obj face file imports okay, but then 3dCoat forces me to choose between accepting or declining a "merge," but whichever choice I make the nice face form disappears or breaks into small pieces. How can I successfully import an obj face and then begin the voxel (muscles) hair application to it?
