First of all I cannot create an alembic or obj sequence from my main apps that is a specific chemistry application I've read a bit of the present thread but it doesn't seem to solve my issue which is the following. I create a dae sequence (correctly numbered) when I try to give it as an input to my Houdini it load the first one but not as a sequence (even if it correctly recognize my fy files as a sequence in the file dialogue). It load the first file and when I click play to see the preview of the animation nothing happens. Also it would be nice to load the files without all the nodes but that's another issue. For now it would be a GREAT deal to succeed in importing it Jojo
Animation for FBX and Collada (DAE) is built into the file format and typically not used as a sequence.
What you can try is to import a single frame then dive inside to the File node and unlock it by CTRL-CLICKING on the orange lock flag. Once the File node is unlocked you could try using $F to drive the file name. Then Houdini may read it as a sequence. If your dae sequence has zero padding in the file numbering make sure to adjust the $F accordingly (i.e. my_file_0001.dae needs my_file_$F4.dae).
