Mental Ray Fatal error

[eddgarpv]

Are you using any geo shader? Maybe something related to framebuffers?
This has only happened here when using ar_GeoInst (Geoshader for instances) and the name of the object to intance is wrong.

Thanks for the respnose eddgarpv. I don't have any geoshaders in the scene. I narrowed the issue to three objects that have transparent lambert shaders applied to them. If I delete them, the scENe renders OK. I've decide to use render layers to solve the problem.
