I've been experiencing a bug with railclone objects in certain, seemingly random, scenes when using vray distributed render in Max 2014. The render nodes will render the scene, but as if all of the railclone objects have been hidden/deleted. However, the local host, and for some reason one of 5 render nodes, will render the scene correctly (with RC objects). This causes a sort of checkerboard pattern, where any bucket rendered with the local host is correct, while any bucket rendered with a render node will not contain any railclone objects.
I've managed to isolate this to a specific railclone object within a scene. I had a scene with 4-5 different railclone objects, and everything was rendering correctly across all nodes. Then I created the last RC object, which triggered the issue. Once this issue has been triggered, it seems to carry through in the scene forever. Also, copying that particular railclone object into a new scene will bring the issue with it.
I've attached a simple .max scene that experiences the issue. It contains 2 railclone objects. One is from the default library that rendered fine when the scene was new, and then another that I copied into the scene that triggered the bug. There is also a box and a dome light. I also attached a screenshot showing what the checkerboard looks like rendering.
As far as I can tell it seems to be an issue with the railclone object itself, since copying it into an new scene causes the problem. But I can't figure out what it is about this particular object that is causing the issue. If I delete the problematic RC object and run the garbage cleaner script gc() in max script listener, then the first railclone object will start rendering again correctly. Rendering different camera angles, closing and reopening the scene, and resetting the local host as well as the render nodes do not solve the problem. All software is the same version on all machines (version 2.5.0).
Thanks in advance!
