Guest janosch Posted November 5, 2016 Share Posted November 5, 2016 (edited) hey guys, I exported my alembic cache from houdini to maya, but I didn't get uvs from houdini. I still have uvs in Houdini. Anyone had this problem allready? I tried to transfer uvs from another mesh on top of my alembic cache, but then the uvs are moving. Because the order isn't right. I tried to change the order, but it didn't work. thank you! Edited November 5, 2016 by janosch Quote Link to comment Share on other sites More sharing options...
mosssi Posted November 5, 2016 Share Posted November 5, 2016 Hi, If you post a hip file it's easier to answer. But you can check if the uv attribute is on vertex or points. maybe it's different. also you can use additional uv attribute parameter on alembic ROP and add uv there too. And of course check your ROP for what you are transferring in attribute fields. Quote Link to comment Share on other sites More sharing options...
Guest janosch Posted November 5, 2016 Share Posted November 5, 2016 Hi, thank you for your fast response. you can find the file attached. test_alembic.rar Quote Link to comment Share on other sites More sharing options...
mosssi Posted November 5, 2016 Share Posted November 5, 2016 I had a huge cooking time with your file. As I tested so far Maya can open uv when it's an attribute on points, not vertex. but you can't change uv attribute with an "attributePromote" sop so let me check again.

Guest janosch Posted November 5, 2016 Share Posted November 5, 2016 yeah, I read allready and tried to transfer the uv in maya, but it didn't work. I think, I can shift the attributes with attribute promote, but I don't know how. Quote Link to comment Share on other sites More sharing options...
mosssi Posted November 5, 2016 Share Posted November 5, 2016 It's simple, just put an "attribute promote" sop before your "ROP alembic". change "original class" to vertex and choose uv in "Original name" field after that. use and alembic sop + an unpack sop for loading and checking your exported model uv in houdini.

Guest janosch Posted November 5, 2016 Share Posted November 5, 2016 I checked it. I lost the uvs after third scattering process. mh Quote Link to comment Share on other sites More sharing options...
Guest janosch Posted November 5, 2016 Share Posted November 5, 2016 hey, I tried this methode and yes I got uvs, but there are wrong. mh Can you send me your file? Quote Link to comment Share on other sites More sharing options...
mosssi Posted November 5, 2016 Share Posted November 5, 2016 That's what I have too. This is what happens when you convert vertex uv to point uv and it's not simple to fix. Let me work on that tomorrow. Quote Link to comment Share on other sites More sharing options...
