Hello! 

I'm having some issues with keeping the UVs on an object that i'm breaking in Houdini.

I checked and the UVs are in the imported geometry.

In the DopNetwork, after the rest node the UVs are still there, but then they're gone. How can I preserve them until dopimport and further Alembic Export??

Can't post any files but this is a simple setup with a Voronoi breaking geometry with a scatter over itself.

Feel kind of dumb and might be overlooking something either very basic or very important.

Thanks in advance.

Cheers

Hello, have you tried to « unpack » your geo after the DOP ?

By the way, if you break an object that already has UVs, you still need to create UVs for the newly created primitives belonging to the « inside » group.

Let us know if it works.

Hey there! Worked perfect! Thanks. I really had the feeling that I was missing something realy simple. It's been a while since I touched Houdini and today I had to deal with the beast; I'm kinda discovering it again.

Cheers! And thanks again.

Hello! Well, I kinda just ran into another problem. After unpacking the Sim after dopimport I can see the uvs via uvquickshade, but when I export the Alembic file with rop_alembic the Uvs appear missing in C4D.

What's wrong?

Thanks!

Check at which levels were the UVs (vertices, points ?), and look if you have checked the Save Attribute in the Alembic render node, and which attributes are saved for POints, Vertices etc. (you may need to specify Uv).

Or maybe that’s a C4D problem, with packed geometry also in C4D, but then I can’t help U :-)

Hello again! Yup, found it while waiting on someone's response; After the merge of all the sims I needed to promote de uv attribute from points to vertex. Guess C4D can only read Vertex UVs.

Thanks anyway! Cheers!
