[C4D] I need help! / Re: Python remove render region in VFB

« on: 2022-10-04, 12:43:56 »

Hi,
setting False into CORONA_SETTINGS_RENDER_REGION_ENABLED parameter of renderer video post should work - and it seems to be working here. I am attaching example that I tested here - running this script for any Corona scene should ensure it will render with render regions disabled.

Code: [Select]

# Get Corona renderer video post
PLUGINID_CORONA4D = 1030480
videoPost = c4d.documents.GetActiveDocument().GetActiveRenderData().GetFirstVideoPost()
while videoPost and not videoPost.IsInstanceOf(PLUGINID_CORONA4D):
    videoPost = videoPost.GetNext()

# Disable regions
if videoPost:
    videoPost[c4d.CORONA_SETTINGS_RENDER_REGION_ENABLED] = False

Note that setting this will either disable it immediately in VFB in case the current document is being rendered in VFB at the time you run this script or disable it for following render in case the render is not in progress.
