Hello,

So I have a for each loop to generate LOD level of the same object.

I'd like to know how to combine each iteration of the loop in order to export them to Unreal engine.

I linked the file, any input would be really welcome. Thank you.


My houdini version is 16.5.571, my Unreal Engine version is 4.20.2.



Thank you for your time.

Hey,

So as far as I understood :

The for each node increment every frame.

Objective : Merge the result of every increment on a single object.
Problem : Only one increment is accessible at any given frame.


Very bad solution : Write file every frame then read and merge them before outputting to Unreal. (Doesn't work because when using my hda only one frame is computed, the goal being not to have to do anything in Houdini)


To sum it up : I seek a way to run “lodNumber” frames of simulation and merge the result of every frame into a single output.
