Hello gang, sorry if the question seems obvious but I'm an absolute newbie here 8)
I would need some help with imported Alambic… I imported a whole XSI scene with multiple models that contain simple polygon meshes (low poly modeling).

I don't know what's the matter but I can't subdivide them in Houdini. I'm not trying to simply increase the polycount, I want a non destructive subdivision on these meshes just like in XSI.

So here is what I tried:

If I create a cube polygon mesh, I can go to parameters > render > display as = subdivision surface.
But on this imported Alambic geometry, this drop down is not available.
Do you have any idea why?

Thanks guys,
Gz

I have noticed, if you import an animated alembic, you pretty much cant use modeling sops on it, even if you unpack the geo (which actually makes sense, doesnt it?). I suppose your problem has the same cause..

rewrite your alembic file as a bgeo sequence and reload it with a file sop

put a convert node convert it to a regular geo, then you can do whatever you want

Thanks for the answer and sorry for the outrageous delay file sop worked!!!!

Hmmm I'm back because, once again, I'm confused here.
So the XSI scene imports fine and I can subdivide its multiple objects, but… I can't select anything! It's like the “file” node is only refering to an external alambic file that can't be altered…. How can I select things and start working on them?
Thanks :?

Just load as Houdini geometry.

I don't see this option…
Well now I used FBX and it works better. I just get the geometry but at least I can start working on this scene LOL
