I don't know how's the sop part of the file looks like so I could be wrong, but I could think of two things that could be causing problems:

1. The geometry file name attribute didn't pass it to the file node in sop correctly
   
2. Flipbook could have problems working with pdg since it's integrated with the viewport, use Opengl or mantra instead
   

Can I use OpenGL or Mantra do just do a viewport screenshot? Is there any documentation for it in the python docs do you think?

Thanks again lobachevscki for your sage advice.

Alright I figured it out. Here's the very simple solution that I'm posting here in case anyone else googles for the answer and can't quite find it.

Problem:
When exporting fbx from ROP FBX node, the model is named whatever the last node in the chain is.

Solution:
In my case, my model has a 'name' attribute which is the correct name for each primitive, toggling the option in "ROP FBX Output" "Build hierarchy from Path Attribute" and setting the "Path Attribute" to 'name' works great.

Here's my setup





Thanks all,
Colin

Hi!

I consulted the Everything Procedural Discord, that you might want to check out if you dont know about it, it is a good forum for questions and consultation.

Find attached a very barebones example of a workaround for this problem.

Im attaching only the HIP file out of simplicity, but the HDA the TOP network requires is just a simple Cube SOP where you change the scale, nothing else.

This approach shown here can be scaled and adapted to other more complex workflows, which is my case, but in fact if you are just only exporting stuff this might be enough (mind you the attributes name can be a problem).

Without getting into much detail (the HIP is here for that), what you do is to write to a cache using the hdaprocessor or even the very ROP Geometry node (if you instead of using and HDA are directly batch editing from the a geo environment) and then recast that cache with a ropfetch. The ropfetch node will write to disk with whatever options you have in the ROP FBX Output if you correctly set up the parameter references (again, in the HIP).

If this is not enough it probably will help you anyway.

This works splendidly, thank for you taking the time to create the .hip file and everything. The only issue I'm having now and am trying to figure out is how to have the object names transfer as well from my input.

e.g.
in the file `art.fbx` I have a mesh named "art_LOD0", "art_LOD1" when I export from the ROP it names my new objects after the last node in the chain which in my case is "autouv1". I'm still pretty new to houdini so I'm checking if I need a "name" attribute or something like that.



Best,
Colin

Hi!

I consulted the Everything Procedural Discord...

I couldn't find this discord community, I did find this one though, is this the one you were referring to?

https://twitter.com/thinkprocedural [twitter.com]

@lobachevscki, Thanks so much for your replies.

In the future for support, like this, I figured a forum post would be more ideal than contacting via email so it could help future users.

I didn't know about the discord either, so thanks for that reference. I'll try this out later today and see if it works for my pipeline setup.

Best,
Colin

I'm trying to create a screenshot of my model library which I'll pipe into ImageMagick to create a montage. Rather than rendering each model, I'd just like to take a viewport screenshot.

My setup is pretty simple.

* A filepattern node which scans for all .fbx's in a folder.
* A geometryimport node to pull in the geo.
* attribcreate to create a string with the key "image_path" and the value pointing to where I want to save the flipbook image
* lastly a pythonscript node to create the viewport (flipbook) snapshot



When I run it, I get correctly named images saved to the /flip directory, but they're all the same content.



I've tried calling .draw() on the GeometryViewport and a few other things.

Any advice?

Quick question about exporting FBX's using the "Write Outputs" on the HDA processor node in PDG.

When I specify a FBX file as the output from the hda processor node, it saves each fbx in ascii format instead of fbx binary format. 3dsmax isn't able to read the fbx ascii format.

Any way to get this to work?

Thanks,
Colin
