Corrupted Physical Camera

[calberto.cart]

Hi there, a couple of months a student sent me a file that had a seriuos problem while rendering with Vray, 3ds max stopped responding in Render process, it stucked on "transforming vertices", altough IPR worked fine, I checked the whole scene and the problem was the cameras, as soon as I created new ones, the problem was solved.

The thing is that Im curious about this, I´ve cleaned the scene with Prune Scene & SiNi Forensic and it showed that there are some animation issues, I hope you could help me to understand how to avoid this, because he says it has happened once more, but now he knows how to solve it.

I have already sent the file to Chaos and they also have test it with Arnold and the error ocurrs there too, also I tested in Corona but theres no issue there.

I share the file on 3ds Max 2020 only with the cameras and a plane with a box, also a video showing the issue.

Best Regards

I only have installed Max 2022 so I can't review your file.

But if the rendering is getting stuck it can be many reasons.

Geometry, Textures. Lights issues.

The preview renders only use Ligh cache to calculate GI, that method is fast but not precise. so it may be able to skip any other issue

What you can do is overwrite all scene material, and do a test render, if that work, then you know it is a material. if it doesn't work then it can be a geometry problem.

Other than that, I would have to look at the file.

Thanks for the tip, but as i explain, the scene didnt have anything, i did exactly what u said, and the problem was with the cameras, once they were replaced, everything rendered perfectly, i cannot not show the original project because im not allowed to do that, the file that im sharing only have those cameras and simple geometry to show the error, i wanted the team or someone else to analize them in order to know, if its possible, what causes the corruption.

My bad, ill reupload the file in Max 2020.
