Error: [texturesys] unspecified OIIO error halfway through a render

[Anonymous]

Hi,


When rendering, we will randomly get "Error: [texturesys] unspecified OIIO error" and then remaining buckets thereafter will give texture error color for random shaders.

What could cause this? Is this related to something with networks?

Which version of HtoA is this and which OS? Do you have a simple example scene?

There is usually more information logged. It should give the filename too...

Maya 2022 Update 1 + MtoA 4.2.2

We have the same errors which only reported by AMD ThreadRipper(3970x)  machines.

Random texture files are reported with unspecified OIIO error.

The above errors only happen by rendering in AMD Threadripper 3970x machine.  The same job run smoothly on our other Intel and AMD Ryzen  5950x machines.
