If I understood correctly Vulkan will eventually take OpenGl's place in every viewport related stuff. Does this mean that we will eventually get a Vulkan rop similar to the OpenGl rop for exporting viewport images directly?

Thanks!

Flipbook ROP is the replacement I think.

The OpenGL ROP only renders with OpenGL. For Vulkan, we started fresh with the new Flipbook ROP, which is the Vulkan equivalent of the OpenGL ROP. The clean break allows it to run with fewer requirements on headless machines (no X11, for example).

You are right, just saw this info from this thread: https://www.sidefx.com/forum/topic/97655/?page=2. [www.sidefx.com]
It would be nice having it somewhere in the documentation since it is a new node and even its documentation page only hints about Vulkan.
