Hope you can help me. When using houdinis Uv packer(uv layout) all my UVs gets separated at at faces edges when exporting from Houdini to maya. Any Ideas? Thanks.

That's how vertex attributes work in Houdini. It effectively separates every point. If you want the attribute to be fused, then it needs to be a point attribute, where one point can share multiple vertices.

There is a node which can help fix the unshared uv problem when using vertex uvs. The ‘Vertex Split’ SOP will unshare points when the the value differs between the vertices of a point, and optionally move the attribute from vertices to points. When the threshold attribute is set to ‘uv’ and the promote to point option is enabled, this will effectively merge the uvs. Unfortunately this will unshare the point positions where the uv seams are located, potentially affecting smoothing/subdivision. I'm not aware of a proper solution to this issue, unless the alembic exporter itself can take care of it.
