This issue never happend in v4.1.6.
Unfortunatly I cannot send a test scene because I was unable to replicate the problem, but it happend in 3 different projects.
In all projects the issue is EXACTLY like described below.
I use 3ds max built in batch render dialoge to setup my renders.
Cameras 1 and 2 render excellent, but in all projects always camera 3 doesn't render the Forest object properly.
All pojects started in 4.2.2 so it is not a migration issue.
Also, this forest object is visible in cameras 1 and 2 and also, in camera 3 the same object which is a little far away from the camera renders without issues.
This is a crop image of Camera 3:
Blue mark is rendered OK.
Red mark is the ISSUE.
NOTE: both are the same Forest object!!All paths are networks paths and visible to all nodes.If I render the same camera 3 without batch render, everything renders fine.All nodes including WS are:Windows 8.1 Pro Update 1 64bit
