Static objects that have been 3Dscanned with an accompanying texture that need to be " polished" and 3Dprinted , would benefit enormously from a direct workflow.
I dream of: Load scan, sculpt, paint, sculpt, paint, print. The texture needs to be projected on the outside of the voxelhull, in such a manner that any additional piedestals are easy to add without losing the texturedata in the process. Then determine Thickness; 3,5 millimeter to suit the material, p.e. bioplastic or bronze.

." Also if you need some features to look sharper you may increase density locally. This is obvious advantage over just etxture painting.
"

Was thinking about this today.

But I think we all appreciate that there are options to approach a project differently in 3D Coat whatever your pref.

Where is the new vertex painting facility folks? Love to give it a spin but can't see it.
Maybe I'm running the wrong version 3.0.4C

Ah Ok just downloaded the latest version for Mac - so you can just start off in the paintroom in voxel surface mode - sweet :-)


Ooooh it's lovely - thanks Andrew!!

I think I've been in 3D long enough to know what anti-aliasing is and that I can at least paint a straight line on a texture map without a hideous amount of pixelation..."aliasing" (better?).You call it a rant, I call it countering all this hype a good dose of reality. The attached image is using a 4k map. Could get the same on a 2k. Neither is as hard on the system as having to crank up the resolution on mesh (and then adding vertex color data on top of that).

What advantage is that? You mean you can't increase LOCAL resolution on a UV map by scaling the islands/cluster where you want extra resolution in the same manner? It's been done for a few decades now. How is this some major breakthrough? Ptex will do essentially the same thing, but on the fly (increase local areas of density).


I imported a midpoly model for PPP, set texture size to 4096. Drew 4 yellow lines where aliasing could be clearly seen at 100% res.
Export Diffuse. Opened the TGA in photoshop. Resized the image with bicubic (best smooth for gradients) or bicubic smoother (best for enlargements) to 2048 x 2048. Aliasing disappeared at 100%. My target resolution was 2048x2048.

Just ran into a bug in 3-7-05B for the mac. Attempts to switch into proxy mode creating hangs.Consistant and repeatable.

While I again finding myself disagreeing with the adversarial tone, I do agree with Abnranger that vertex painting is of limited value for high res textures. 16 million poly's is about on par with a 4K map, but that's not that much really. Depends on the kind of work you do - that's entry level for many textures that I require.

That said, vertex/poly paint is a *great* system for low to medium res texture work. PTEX or PP painting works well for higher res work (to a point - it is pretty laggy with high res and high res brushes for now). The only downside of having both is the split focus in development will likely mean that neither gets fully sorted out anywhere near as fast as if there were only the one.

No Technology suits all thinkable requirements at the same time.
4k even when entry Level for your highly specialized work is certainly not what everybody will need. Those who need a Tool to quickly create Design-Concepts
can come along with far smaller Texture--Sizes. A 2k texture which isn't shabby for many purposes only requires 4Mio Polygons...
Good also least that you still go the conventional Low Poly Route then - it's not being abolished after all. That said - I would not at all be surprised if Andrew came up with
some sort of intelligent System to work on even far larger meshes as also possible in Zbrush with HD-Painting.

Vertex-Paint was as he said a thing he had planned for long time already and I think it is good to deal with it when the Application is still relatively young as it may have
greater consequences on how one has to plan the GUI. Especially when also parallel Painting and Deformation would get hooked up...
The new System opens 3DCoat even more to non Digital Content Creation Industries. Medical users for instant who create Colour Facial Scans now could use 3DCoat
to solidify the Model with Voxels and for fixing some Seams on their Scan-Results without having to go through a Retopo-Process/Baking Process.
One thus far can spend 6Digits on such Scanners but one could not Postprocess them properly in any straightforward way.Going the Retopo-Way is no option for those
Medical Users - it makes no sense for several good reasons.

I think it's also utter Nonsense to say that having Vertex Painting and the conventional Route being developed at the same time will as clear consequence slow down the
Development Process. Things are not always as linear and it's impudence to think that we Customers could forecast how things will further develop.
Of course it's gotten an even more complex Project now. But when Vertex-Painting makes new Users maybe also from other Industries purchase the Software this could well pay off
and additional Developers can get hired.

OK, I managed to transfer vertex painting to blender (BTW obj isn't working, LWO does.)
So what can I do next? I can't render it.

Hello andrew and thanks a lot for 3d-coat again.

I just installed the last beta and all of a sudden I did't have any shaders left available in the voxel-room.

already tried to deinstall everything and reinstall (newest beta) again - no shaders left.

I then reinstalled the previous beta and voila the shaders were back.

just to let you know.

a Tool to quickly create Design-Concepts


for those who need it.

It also helps new modellers get started without having to get bogged down with technical details.

Scanning company's will also find it useful.

found this on google. don't know if its useful. Blender - Vertex colors can be painted by switching to Vertex Paint Mode, however, it will not show up in the render unless you check "Vertex Color Paint in the Materials ..

That's what I wrote too. :)
A simple example of something previously impossible:
  • Download the free program 123D Catch and 3DScan some item from you House just by using a simple Camera
  • Load the Mesh as Voxels, Solidify and correct small or large defects
  • Load Textures captured by the Camera as Vertex Colours
  • Do Model Modification to your Hearts desire and blend them seamlessly with the Scandata
  • use Fill Voids followed bý extract Skin
  • save out as decimated .ply
  • create colour 3D-print at service-supplier

I assume you are using cycles, create an Attribute node via Add -> Input and type the name of the vertex color map into the field on the node. Then just hook it up to the color on a shader and it should render.

I think you basically just said the same thing in more words :) I agree that VP has a lot of use and potential, but agree with ABN that it's limited at this stage for hi-res work.

It is neither impudence or nonsense to say that development is likely to be slower - it's just logical given: (a) limited resources and multiplied tasks, and (B) the history of development thus far with 3DC and other software. Sure, sales could go up and so could development, but that is *less likely* to be the case. In any event, it's not a criticism of anyone - it is just how things are. Only time will tell though :)
