OBJ UDIM Export Creates Material Per UDIM

Development Asset Creation
1

OBJ UDIM exports correctly except the model has a material for each UDIM. This is counter to the UDIM workflow where the model should be one material. Can this be fixed?

Will have a look at this and discuss with the colleagues. Thank you for mentioning this.

Yes please fix it also for FBX

Are there any news to this UDIM /Maya /Material Problem. I just ran into this in the middle of a production.

I thought this has been fixed long time ago…now I can do my UDIMs manually.

Hi L.Groeger, what version of RealityCapture do you have?

6

I have version1.1.1.15122

7

Is it possible to download newest release if it is also there? Do you have the same problem as in the first question?

8

Great ! this is working now with the latest version.That could  have saved me a whole   day of work .

This does not and has never worked for me, It’s been a nightmare for years…   Can someone please explain to me how to do this?

Hi Steffen, what is your workflow here? Which version of RealityCapture do you use?

Hi Ondrej!

Im using the latest version and I am exporting multiple UDIM textures per model.  So if I export an .obj and open it in Substance Painter I get multiple materials with one texture per material instead of all the udims loaded as a single material.  I can’t find any options to change this on export…

Hi Steffen, I noticed that you created a ticket for this issue. So as you know, this is a bug which we are solving. Sorry for the inconveniences.

Yes, but I have not gotten a reply saying that you are working on this.  I got a link to a youtube video that shows how to fix it after export, but that is taking quite awhile to do for each model, so I hoped this could be adressed so we could finally have the option to export as one material with multiple UDIM textures.

As you can see earlier in this conversation from the user “L.Groeger” he/she says that this works in the latest version, so that’s why I replied on this thread, maybe I had missed something.

Here is a list of community posts about this going back 6 years, (these issues have still not been resolved as far as I can see):

This one has a very good description of the problem (2 years ago)

Anyway, thank you for your reply, I (and probably many others) would be very grateful if this was enabled in the next release.
