Can you paint across those surfaces and save those separate maps? Im searching to know if this features exists and i can't find it.


What is "it"? I don't use UV tiles so I wouldn't know anything about them. I know 3DC can certainly paint across separate UV maps and save them seprately. I do that all the time. Can't answer if mb or zb can.

I don't know about 3D Coat, but Mudbox was designed from day one to sculpt/paint across multiple UV tiles, which is not the same as multiple UV maps, or multiple UV islands on a single UV map.

Sorry typo

Yes i meant painting across multiple UV tiles.

So is this something it cannot do?

Like I said I don't use tiles so I couldn't say. If that's you that asked on the 3DC forum, I approved your question so maybe someone else there can.

Greg: Technically from day one mudbox didn't have painting or UV maps. It didn't have those until it was several years old.

I must admit this isn't something I normally do, so I did a quick test.

Yes 3DC can paint over multiple UV tiles, surprisingly smoothly as well. On import you just have to select the option "convert tiles to UV sets" (off by default), then on export of the texture select export all UV sets.

Thanks, hope someone can answer it over there.

And i think Greg is right, from v1 of mudbox it has always supported exporting of maps to multiple UV tiles. It was only displacement/bump/normal data at the time but multi UV has always been a focus. Its much more production friendly that way.

Hope 3d-coat can match mudbox in this respect.

Edit:// yog just seen your post.

To my knowledge UV sets are just islands of uvs right that live in 0,1. So is it scaling the UV down into 0,1 or is auto-fitting (translating, rotating) them to make it all fit? It sounds more like a form of conversion than support because all that texture resolution will be reduced.

Actually it is still using UV tiles in the accepted sense, i.e. 0,1 , 0,2 , 1,1 , etc

Upon conversion it looks as though in the 3DC UV editor you can only see one tile / set at a time, but upon export it is exporting all the individual tiles at full rez.
The layout of the UV tiles remain unaltered, so it is not repacking them, and there is no overlapping seams, so it not dumping all the tiles onto the same UV space
Maybe not as elegant or as automatic as Mudbox or Mari, but it appears to work reasonably well.

Perhaps I was wrong, I don't recall anything about UV maps when I used to use mudbox and I just went through the old skymatter site via Archive.org and couldn't find any mention of UV maps.
