Problem display, UDIM and memory with Maya rendering Arnold

[montoirmathieu]

Hi, i have a problem when i try to render a vehicle of my student movie in maya on Arnold, the render happens to end but there is a display problem nearly on the totality of render.

here a video of the render completed : https://youtu.be/kgbp2VHebYw

I used UDIM and i think the problem come from them, because the bug affect only the texture that use UDIM, for example the garbages in the bin, and the pipes doesn’t use UDIM and are not affected.

There is no error message during the render.

Maybe it’s the bucket size ?? and a problem of memory ??

Numbers of UDIM used , size of the map used ?

Here my configuration, maybe the problem comes from here.

Thank you for your time, have a good day.
