Get / export actual geometry of instances

Postby mickcullinan » Fri Jun 07, 2019 5:14 am

Hi all,

Is there a way to get the actual geometry of instances and export? I'm using TD to generate a dot pattern using instanced circles in a Geo, and would like to export the resulting pattern as a vector or FBX or similar for use in another program.... is this a runner?

Thanks,

- Mick

Anyone have any ideas on this? It might just not be possible. I was able to use a raster version of the pattern for now, but as the project progresses I think I am going to need the vector information of the same pattern.

Thanks!

you could export the data back from the shader stage (complicated), or redo your instancing with copySop instead, less efficient for real-time but you can save the resulting sop

Currently the easiest way to do this is with the Copy SOP. Use that to create your geometry instead of instancing. It's not fast for rendering, but it'll work for exporting.
