Distributed render error, with workaround
Hi,
I have encountered an error with V-ray for a number of versions, connected with distributed rendering. I will try to describe the symptoms. Where I talk about a file it is a generic file, but I have examples if required (although there are often large amounts of x-refs and assets connected with the files).
I have a scene with multiple v-ray cameras in with multiple lights, each for a respective camera. When set up, the file will render perfectly fine, using a number of other computers to distribute the rendering by buckets. The cameras in the file will usually render fine for a while, changing which camera and which corresponding light are active, and rendering different sized output from each. Then at some point (not yet identified as connected to any particular event) I'll notice that the distributed computers will fail before starting to render. They will start loading the file, but then crash out, continually until the host has completed the render, or has been cancelled.
I have managed to find a very simple workaround, although it is a bizarre way to solve the problem, and apparently has no logical explanation.
To solve the problem simply duplicate the camera as an instance, no need to change any settings, and render from the new camera. Everything will work fine.
I would like to know if the problem has occurred anywhere else, if there is an explanation as to why the "fix" works, and if there is the possibility of a software fix to solve the problem.
I look forward to hearing your responses.
Kind regards,
Bill Sands
