Thanks, Raul! Nice Holidays :-)

Thanks, that what i needed (only the way to access to the uv view, every time i have bad shortcut i found on internet that screw all the interface)

Great guide 11:42 its banana ,,,

[@brookslee2227]

hi Thank you so much for your fantastic tutorial ! I'm currently using houdini 19.0.383 and there is a node called uvunwrap. I'm a little curious if I could use that node to unwrap the uv!

[@pixeltrain3d]

Hi, I showed the UVunwrap node in some tutorial. I think, in the coffee cup ...

[@sebastienberruyer4110]

Yes! i was waiting for it, thank you again! Fbx won't work with the free version of houdini...

[@pixeltrain3d]

Have you managed to export it? If the rops or file cache nodes don't work in the free version, you can try the following thing: Make a right mouse button click in the last node in your geometry tree (after the uvlayout). Try in the pop up "Save -> Geometry ... Does this work?

@@pixeltrain3d Don't worry, the .obj extension works!

Hi, when I set up the UV flatten in Houdini, the UV display of my banana is upside down, and I would like to find a solution to this.

[@ud3180]

Please do a udim uv tutorial for Houdini. Thank you

[@pixeltrain3d]

Thanks for your feedback. Which Painting Application for your UDIMs workflow would you like to see together in the Houdini Workflow? Any preferences?

That's good, I was thinking 3D-Coat and in the future Mari

[@jasonjin3518]

Hi, I did the steps but the UV is not showing on the box. (grayed grids with letters) used UV unwrap and UV quick shade node And how to tell if your imported free obj statue in houdini has UV or not? Thanks!

[@pixeltrain3d]

Hi Jason, You can check if you have UVs with the middle Mousebutton the the File-Node. Is there a UV attribute?

[@jasonjin3518]

@@pixeltrain3d I did that now and "UV attribute" didn't show up so UI added the UV unwrap and UV quick shade. How do I make sure that the UVs are also on the inside faces in the statue after voronoi fracture? Is it the use of loop node? thanks!

[@josefh8782]

Great tutorial many thanks. Your English is fantastic but just to help you: sew is actually pronounced like so, and suite is pronounced like sweet. Doesn't make any sense, I know :)
