Can't export created animation with DOP

[racdew]

Hi everyone! I have a problem with exporting the assembled animation to Maya in fbx format
The animation of the tower itself was built using this tutorial

The main problem with outputting animations in fbx format:

1. -The animations are in the cache and not cached with the keys exposed as I have done before through the SOP of the network
2. -And for some reason the model is broken into separate pieces that were triangulated 

Maybe someone has encountered a similar problem and can tell you how to solve it

Attached screenshots and source of my project

Do not use .fbx to export back to Maya, either use an .abc or .usd

I need only fbx for the project, alembic is not stored in Maya file only in cache, on the output I want to get from this baked animation on transforms with keys on timeline

There is no keys in simulation and you cant get them with export. If you need keys per each piece you can bake them after simulation and export baked geometry

Can you tell me which nodes are responsible for this? Or at least a similar tutorial if you have one, because I have not found anything similar for my situation(

There is no simple solution to this. First of all where you need keys on obj level or inside geo sop? If on obj level you need to create geo sop per each piece, extract transforms and apply to geo sop and put pies to origin than bake animation with python script. if in geo sop you can just bake with python script.

this is example script for bake camera you need to modify it:

import hou

selectedNode = hou.selectedNodes()[0]

bakingNode = hou.node('/obj').createNode('cam', selectedNode.name() + '_bake')


hou.setFrame(int(hou.playbar.playbackRange()[0]))

for f in range(int(hou.playbar.playbackRange()[0]), int(hou.playbar.playbackRange()[1])+1):
    hou.setFrame(f)
    
    bakingNode.setWorldTransform(selectedNode.worldTransform())
    bakingNode.parm("tx").setKeyframe(hou.Keyframe(bakingNode.parm("tx").eval()))
    bakingNode.parm("ty").setKeyframe(hou.Keyframe(bakingNode.parm("ty").eval()))
    bakingNode.parm("tz").setKeyframe(hou.Keyframe(bakingNode.parm("tz").eval()))
    bakingNode.parm("rx").setKeyframe(hou.Keyframe(bakingNode.parm("rx").eval()))
    bakingNode.parm("ry").setKeyframe(hou.Keyframe(bakingNode.parm("ry").eval()))
    bakingNode.parm("rz").setKeyframe(hou.Keyframe(bakingNode.parm("rz").eval()))
    
    
    bakingNode.parm('focal').setKeyframe(hou.Keyframe(selectedNode.parm('focal').eval()))
    bakingNode.parm('aperture').setKeyframe(hou.Keyframe(selectedNode.parm('aperture').eval()))
    bakingNode.parm('near').setKeyframe(hou.Keyframe(selectedNode.parm('near').eval()))
    bakingNode.parm('far').setKeyframe(hou.Keyframe(selectedNode.parm('far').eval()))
    bakingNode.parm('resx').setKeyframe(hou.Keyframe(selectedNode.parm('resx').eval()))
    bakingNode.parm('resy').setKeyframe(hou.Keyframe(selectedNode.parm('resy').eval()))
    bakingNode.parm('winsizex').setKeyframe(hou.Keyframe(selectedNode.parm('winsizex').eval()))
    bakingNode.parm('winsizey').setKeyframe(hou.Keyframe(selectedNode.parm('winsizey').eval()))
    bakingNode.parm('shutter').setKeyframe(hou.Keyframe(selectedNode.parm('shutter').eval()))
    bakingNode.parm('aspect').setKeyframe(hou.Keyframe(selectedNode.parm('aspect').eval()))
