I came across Houdini Engine for Unity's "Pack Geometry Before Merging" feature. I haven't used it, but it looks useful - "If checked, all the different Unity meshes will be packed individually before being merged into the asset's input."

The problem I'm having is that multiple geometries from Maya will always end up merged down to one geometry. For example, I have one 4-face plane and another 1-face plane. Ideally, I want them to appear in Houdini as 2 PackedGeometry prims, with packedfulltransform and such so I can retrieve their transform data. Instead, they merge to 5 Poly prims and I lose all the per-object transform data.

Even though I can separate prims by name using "For-each Named Primitive", I can't get the respective transform information associated with them.

I can't find any similar settings to "Pack Geometry Before Merging" in Houdini Engine for Maya. But in general, the question is Is there something I can do to get per-object transform data from Maya?

I've attached an HDA that displays point/prim/detail attributes in Maya for debugging.

This is now possible in the plugin bundled with 19.0.1153 and 19.5.787

Great. Thanks for the new feature! Is it possible to add this to Houdini 20 too?

It's already present, however it won't be in the initial gold release - the daily build following it will include it.

Will that work for you?

I'll make sure to get the build that has this update. Thanks!

Hi! I've looked for the "Pack Geometry Before Merging" setting in the attribute editor (Maya), but I couldn't find it.

Here are info from the Houdini Engine pref. in Maya.

Houdini version 19.0.561
Houdini Engine version 4.2 (API:11)
Maya 2022

or the above Houdini Engine version doesn't have this feature?
Thank you.
