Uvs are flipped when sent to ZB

[canderled]

Hello guys, is there an option or a way to avoid aving the UVs being flipped when sent to and imported from ZB using the GOB ? this is specially annoying when working with udim.

late, late reply. but this is actually kind of a weird Zbrush issue. Zbrush flips all its UV's, so they're likely having to do some conversion along the way?

Yeah, I agree with Canderled. Please don't flip UVs via GoB. This practice makes working with displacement maps in ZBrush much more complicated. When you have a character with many flipped UDIMs, baking displacement maps in ZBrush causes incorrect UDIM naming, complicating our work in the VFX and game pipeline. I noticed that only Maya GoZ works without flipping UVs, which is crucial. Other GoZ versions, like MODO and Blender, are flipping the UVs. Could you add an option dont flip UV?

Is there any chance to have this option in an upcoming update? This is the most important feature for us here in the VFX and game development industry. Is it possible to support you financially to speed up the development of this feature? Thank you!

uv flipping has been added to the latest release https://github.com/JoseConseco/GoB/releases/tag/v4_1_2

Awesome news! I’m not sure where to find this option. I tested it without changing any settings, but my UVs are still flipped.

[kromar]

in the addon preferences you should find options for the flipping

I didn’t see this option at first because I didn’t restart Blender after removing the previous version. Now the option is available, and it works perfectly! This is probably the most important update for me! Many thanks!
