Sometimes, when I move models between scenes, (copy and paste or import) or open older scenes, objects will sometimes render invisible until I apply a new material, at which point I can reapply the original material, and it will render normally. (hopefully that made sense).

I haven't been able to consistently reproduce this to find out exactly what the common thread is (not sure yet if it's a specific material type, or caused by materials created in older versions, or what) but it has been a fairly reoccurring issue across multiple scenes

Working in Maya 2019.2 and Octane plugin OctaneRender for Maya 2019.1.4-15.13 [STABLE]

upon further inspection, it also happens with scenes created in this current version. For example, I opened a scene, created in the version which is a bottle on a sweep. The bottle has complex mix materials and the sweep is just a diffuse white with sublte dispalace. The complex bottle showed up fine but the sweep rendered invisible, until I make a new diffuse and applied it to the sweep, after which, I could apply the original material and it would render fine.

So far there has been nothing I can find in common between objects that do or do not have this happen

Works OK on my side.
Could you please give me the scene(s) where it is reproducible and write the exact step-by-step reproduce-sequence?

unfortunately I don't have any scene where it's reproducible every time. Having said that, it's happened on different scenes on different computers so I don't think it's just a random glitch in my one scene. If I find one where its reproducible I'll upload. The only thing I definitely know is it 100% started happening in 2019.2 and none of the . earlier versions.
