I couldn't find any method's that are exposed to the Python API to grab the viewport texture buffer, is there a built-in way or would I need to create a render hook with the HDK? Thanks for any hints.

Moin,

according to the search function, this thread [www.sidefx.com] discusses a way of saving out a screenshot from your viewport. Admitingly I haven't tried it, my last attempts to do something like this failed, so I used a flipbook render instead.
I hope this helps.

Thanks @malbrecht, even though I've considered viewwrite, I wan't to actually keep the texture object in memory without writing it to disc for some realtime streaming. I'll probably need to go the hdk way, but during my testing, I've found this repo, which is good ressource if someone tries to figure out viewwrite.
