where exactly is the U Wrap setting hiding in DS? (not tiling)
would be mortified if i accidentally slipped in a 'u wrap' = true
or is there a line i could add would ensure 'u wrap' = false?
where is it coming from?
is it only from 3ds max models imported to ds?
thanks. cheers

As I said here http://www.daz3d.com/forums/discussion/comment/2079331/#Comment_2079331 it's part of the UV mapping. It's in the UV values, not a separate setting (assuming, again, that this the UDIM offset youn are asking about).
how do recognize if is udim?
talking about stuff like stomemason's duf sets, Gatwyck Shops, DM's Melancholy, muscle car,
thanks
havent seen this u wrap thing on poser stuff, seems to be specific to duf content
i know is trivial, but it's on my mind making shopping decisions, thinking to go back to core poser content.
Generally it will be invisible to the user - Poser and DS just repeat the texture on out of range UVs (so if the UDIM 2 is using u values of 1 to 2 then on rendering 1 will be subtracted from the values to bring them back into the 0 to 1 range).
out of range
thanks richard
how do you fix out of range on a ds vertex model?
Out of range what?
i'm assuming is a vert. the out of range vert that causes the u wrap.
does bryce not have any trouble with uvs on ds props?
Is this a single place that's an issue or is the map tiling and you don't want it to? The latter you can deal with via the tiling setting - set it to 0.5 if it tiles twice with the base mapping, for example. Some more details of what you are wanting to do might help.
basically, i want it to render a ds only set in carrara
.
i want to fix it once and be good to go in both apps
and not have to keep 2 copies of every set, is the goal
setting 0.5 sounds like a fix?! is that going to mess it up in ds though?
it's not a bother to keep an extra saved subset,
but at the data subfolder level. becomes less reasonable the more sets i buy
richard, do you have carrara8.5? might have to see it for yourself?
what Misty is talking about is a duf import bug in Carrara
it also affects some obj files
in the vertex room U is ticked for UV wrapping and should be unticked
rather hard on sets with many models
the solution most use is to edit the .car file in notepad finding and replacing all instances ABoo 23 with ABoo 3 a hack Kakman discovered but really the Carrara developers should fix its a bug.
however this can also be an issue for me in iClone and Poser and there is no fix.
I'm not clear on the issue. Perhaps a screenshot, if you can within the ToS.

a bit on it here
basically it destroys the UV mapping
I see the issue in your screenshot. I don't currently have any other applciations isntalled to have a look at the mapping, though it does appear that out-of-unit-square values (on u and v) are being used to tile some of the maps. It's odd as I thought Poser could use out-of-range UVs to get tiling long-ago, before actual tiling was an option.
not sure when this phenomenon started.
would really like to fix it in the ds side.
been bringing my poser content to my DS library, dragons, etc
doing the geograft fixes, converting general to blended, saving it all DS library.
saving shader presets in carrara. drag it onto the ball.
saving animation NLA clips in Carrara
puts everything together. as a system is working out well, cept for the u wrap.
defeated the worst of the issues >.<
will try the .5 trick
no wants technical issues breaking the creativity flow.
Does an OBJ export work?
import it back in to ds, like a geometry swap?
possible to do the o.5 tile setting on everything in my scene in 1 go?
I meant OBJ export from DS imported into Poser or Carrara, to see if that loads maps correctly.
You can multi-select surfaces to chnage values on all, but you don't want to do that here since you are wanting to keep the tiling (or at least I would think you are).
the Poser example I posted was an obj import.
As I said it seems to happen with newer duf items more, not all the time just the occasional one.
Sorry for the delay in replying, it took me a while to get enough stuff reinstalled to check this.
What options are you using on the OBJ export? In modo, the one on the left has Collapse UV Tiles unchecked while the one on the right has it checked.
