Determine if Maya is currently in the middle of updating viewport

[icapathos]

I want to run custom script regularly, but it crashed after referencing a bundle of files,

I suspect the point that after referencing Maya is updating viewport,

At that point, I can check that is Maya in the middle of a file reading with MFileIO.isReadingFile(),

So I just wonder that I can determine if Maya is currently in the middle of updating viewport or not.

Can I do that with API or something else?

Hi,

I think you could try to add a flag inside the callbacks of MRenderer::addNotification. It provides beginRender event and endRender event.

How can I get the "MRenderer" with Python API 2.0?

It seems that OpenMayaRender does not have MRenderer in Python API 2.0

Hi,

I am afraid it these callabacks are not available in Python, please use C++ instead.
