The system cannot find the file specified.

Hi,
we are getting this error with UDIMs. For example we have c:/color.1001.tx,c:/color.1002.tx,c:/color.1003.tx,c:/color.1004.tx,c:/color.1005.tx,c:/color.1006.tx and we always get some random error like this

Bitmap file "c:/color.1368.tx" failed to load: error reading file:2: The system cannot find the file specified.

This file ofcourse doesnt exist so why VRay trying to load it? We have version 5..10.01.
Thanks

Could you send (or attach here) a simple scene where the issue is present (along with the UDIM tex) via the contact form so we can take a look? Address it to me in the subject and mention this thread in the message.

Hi I have just send files you need.

Hi thanks for the scene! The issue is reproducing and we will have to investigate further into it.

Best regards,
Alexander

And does it have impact on performance?

[alexander.kazandzhiev]

I doubt it as no additional files are loaded. It's peculiar that there are two modifiers applied on the geometry one OpenSubdiv and VRayDisplacementMod, actually the combination of them both seems to be producing the wrong coordinates.
At least as a workaround could be that one of them to be disabled. And the VRayDisplacementMod already has an OpenSubdiv mode, so maybe the other is not needed if this suffices.

Best regards,
Alexander

Interesting. But it is happening also with objects without both modifiers. And also I tought that is necessary to add some subdivs modifier before vray displacement to work correctly. Without it it, it looks odd.
