hi all. I'm trying to get my rbd simulation into unreal, the RBD to FBX rop works.!
But only if I export my data directly from the dop sim. I'm looking to modify somethings after the simulation, so unpack, some editing, and re packing. After this I'm not able to get the animation back into unreal.
What attributes need to be present on the geometry in order for it to export correctly. I've tried to preserve all of them, but still struggling to get the animation a cross.
I took a look at the script inside the rop, but it wasn't obvious to me.
cheers

Hey!

The RBD>FBX uses Packed Primitive Intrinsic Transforms. If you unpack and repack you will probably lose those. You can however set them yourself using: http://www.sidefx.com/docs/houdini/vex/functions/primintrinsic.html [www.sidefx.com]

This thread also seems to go into the details on how to do so: https://forums.odforce.net/topic/18961-packed-primitives-intrinsics/ [forums.odforce.net]

This could be something our tool can generate from custom attributes though. So if you need it, please submit an RFE to support

sweet, thanks for the reply Paul.
Yeah that'd be useful to generate through the tool. Now I'm aware I can look out for it in the meantime. It just caught me out
