"Support multiple UVs per vertex/face", You can have this in 3DCoat. You have to do a little setting up in the retopo room but it is not hard...

The picture shows a AO uv set and a Diffuse uv set I created. They both share the same mesh with identical but separate uv sets so they share the same faces/vertices.

Each UV set can be exported separately also.

I do not work in the industry but tried to understand what is needed and if I can figure it out for 3DCoat I work at it...

The uvs are just for show, nothing is done to them yet... If this what you are looking for maybe I can do a video.

EDIT:

The picture is from the retopo room right before I merged into the paint room showing the two uv sets I created sharing the same faces/vertices...

Again forgive the uv set as I'm just showing that it can be done...

This is something I had to figure out so if it works in all cases or meets all your needs, I would not know... I also might not understand entirely what you are asking for and the above is something, well at least I know how to make multiple uvs set per face/ vertex...

"Support multiple UVs per vertex/face", You can have this in 3DCoat. You have to do a little setting up in the retopo room but it is not hard...

Can you elaborate a little please? Do you mean via uvTiling, uv sets, or both? What is the workflow?

I just tried to import an fbx with 2 uv sets, but while both sets are listed in the import dialogue, and selectable in the rooms, only one of the sets contains a uv map, the other is completely empty. I know both sets are intact in the original file though because if I open it in the ultimate unwrap 3d demo, both sets are present and correct. Using 3dc 3.7.13 - perhaps I need a newer version?

[digman]

My workflow was through retopo room / creating the uv sets / merging into the paintroom.

How are you importing your mesh, into the paint room, into the retopo room.

Remember this something I'm working out as I go. (for some reason I like figuring out problems) I been using 3DCoat for about 5 years so I know a few tricks and aware of some things you can do with it that a new user might be unaware of.

Creating only Uv sets, no tiling...

The fbx problem, since I don't have access to it, I can not really tell what is happening with it... I will test one of my fbx files...

Edit: I exported the ball mesh with the uv sets as a fbx. Opened a new scene in 3DCoat. Imported the Fbx file and both uv sets were correctly imported.

@ carlosa - Its not quite the same thing. UVTiles are not to my knowledge widely supported in real time engines currently, nor do I suspect are they likely to be as they seems to use the space outside the 0-1 range to store the extra sets

Megatrousers it's not only about Real Time.

But for a real time example have a look to Mari, for production Renderer any with a shading language , and for the rest many others who already integrate node or function for it.

It should be really easy to do with any decent production package today,by the way it's for sure easy to assign multiples textures for multiple UVtiles in realtime in a way or another (coding or not).

@Carlosa :None of the 2 options

I just want something easy to preview like:

By the way if you have 60 textures for 20 tiles (3textures/tile), how do you import these maps in 3D Coat ?

As far as i know, i'm probably wrong (i checked very quickly), but it looks like you have to import all the textures per channel by hands .

So 60 textures to import by hand, without anyway to script something .

I can see the usage in an external application where you are linking to different UV sets, but that seems beyond the scope of what 3D Coat's designed for. You can always modify the UV's however you like > bake what you need to and export the mesh with those UV's and texture maps. In Max I would import the different files into the same scene > apply a UV Unwrap modifier to each mesh > save their UV's > (you can now discard the extra mesh) load the newly saved alternate UV's into a different UV channel.

But trying to work on the same mesh inside of 3DC with different UVs (for the same polygons) is too convoluted. I personally think that's better done externally as 3DC's purpose is to deliver assets ahead of this step in the pipeline/process (shading//lighting/rendering). But perhaps it might be something to add as a feature request.

[megatrousers]

I import the model (fbx) for per pixel painting. The retopo room and how it relates to the other rooms is something of a mystery to me at the moment.

Actually, all the merging stuff confuses me a bit.

If I import as a retopo mesh, 3dc doesn't ask about uvs at all, but imports (and displays in the uv preview window) one uv set.

I had a look at your thread here:

http://3d-coat.com/forum/index.php?showtopic=7263

Do your methods require the sets be created in 3dc?

I think if the process is this involved, I would ultimately lose more time than I save. Thanks for your efforts though.

I suppose what I'd like is to be able to import a model with 2 sets each covering the same polys, switch between them (and see them!) freely in the uv and paint rooms and export the model with the sets intact. An additional option in the UV room to [Copy selected faces to] in addition to moving them would be gravy. Maybe if enough people deemed such a level of support useful, a feature request would be appropriate, but I know Andrew is swamped with a million other things.

How would you do this in Mudbox? If you can't do it there, I wouldn't expect 3D Coat to, either.

I was more comparing 3D Coat to Mari since i heard texturing is the first 3D Coat specialty.

In Mari there's no problem for this.

That's true, but Mari is designed to handle more complexity than 3D Coat. 3DC is more of a straight forward, no-nonsense, 3D Texture painting tool. It has a lot of capability, but it still has areas in need of improvement. Large Brush sizes tend to still be one of those. I've requested layer masks. In both cases, Mudbox is a step ahead of 3DC. But overall, in terms of number of features/versatility, 3DC is a more complete Texture Painting toolset. Every release of MB has it trickling in features that 3DC's had for years now.

Mudbox is it's closest competitor and yet over twice the cost...not to mention yearly upgrade/subscription costs. Mari is $2k+ and then you have maintenance to pay for. Doesn't seem reasonable to expect the application to do everything everyone wants, at a fraction of the cost and development staff as the other competing products, does it?

[pixo]

No it's not for sure,it's not fair.

But like i told , i'm pretty sure that Andrew already did the hardest part (ok many bugs to correct first) to be better than the other packages.

The UV tiles stuff is far more easier to do than what he did, i guess at some point it was just a choice between the 2 ways,may be now it will be harder cause of the legacy.

Anyway even if he wants to do it ... that will never happen before 6 months in the best case, many bugs and other features to do.

For the moment ,i just hope to be able to export my textures without any workaround (i have a bug that i reported).

Hi all! I'm from Vancouver. I love video design and modeling. I'm new here.

Hi.... i am new to this site.

Hi, what kind of 3D work do you do? I'd like to verify that you're not just a spammer, so if you could do as most new users do and post what kind of work, art, etc. you do and how you are interested in 3D-Coat, it would help me (and you) greatly. Thanks.

Hey, I'm new to 3DC and modeling in general, I picked up the Pro Steam version and have completed the cartoon rat tutorial Looking forward to creating models for the steam workshop and love the integration that has been implemented.

Quick question, in the steam trailer for 3DC there is a controller/mouse used that looks really nice to use (as i am a bit cack-handed with a standard mouse). Does anyone one know the name of said controller or know of any others that would make my life slightly easier when modelling?
